Cut 36+7 empty, and Hanako will turn away! 400 million insiders have been blown up. Downs Gaubert, please send them away.

Coming to the playoffs, as the No.1 Nuggets in the West, the team continued its dominance. In the first two playoff games, there was nothing unexpected. The team easily defeated the Timberwolves and took a lead of 2:0, and the team was getting closer and closer to promotion.

The Nuggets lead 2-0, and the situation is very good, but the Timberwolves are behind 0-2, which is really pushed to the edge of the cliff, because if the team loses another game, there is basically no possibility of a comeback in this series, so the team must win its first home game in the third game.

The Timberwolves have no way out, and they also gave the Nuggets a duel with the help of their home court, playing a 7-2 start! However, the Nuggets are not vegetarian. After gradually adapting to the rhythm of the field, Jokic stood up and scored points, directly leading the Nuggets to hit a 14: 2 counterattack wave, which led them to overtake the score in one fell swoop. Fortunately, Edwards later scored Timberwolves to stop bleeding, and the first quarter of the two teams was tied at 28.

Brown and Pope were active, and both ends of the offense and defense made achievements. Prince and Downs led the team to retaliate, and the 2 teams continued to pull on the court, and the Nuggets led slightly! During the stalemate, Jokic began to connect teams in series, sending out wonderful passes continuously, and Pope felt very hot, scoring more than 10 points in a single quarter. The Nuggets, driven by two people, launched a 9-0 offensive, widening the score difference to two digits! At the time of crisis, Downs stood up and scored points continuously, stopping the decline for the Timberwolves and chasing the difference to 6 points at half-time.

After the break, the Nuggets still feel hot. Potter, Gordon and Pope scored 3 points in a row, and the team reopened the 2-digit difference! However, the Nuggets’ defense in this quarter was obviously not good, and they got four fouls early. The Timberwolves also frequently used the killing to score points. Among them, Edwards scored 12 points in a single quarter and chased the difference to 6 points again, keeping the suspense of winning or losing.

Braun became a surprise soldier in the last quarter, and he scored points in succession to help the Nuggets re-open the points difference. However, the Timberwolves were adamant, and Edwards and Downs madly cut points and led the team to pursue, always keeping the points difference within 8 points, keeping the suspense of winning or losing! At the last moment, Jokic and Porter scored many points, but the Timberwolves only had one Edwards to support them, but he was unable to make the difference less than 5 points, so the game lost its suspense. In the end, the Nuggets defeated the Timberwolves at 120:111, leading by a big score of 3:0.

At 3:0, the Nuggets easily got the match point of the series, just like the ranking between the two teams. There is no suspense in this series, and the Nuggets lead too much in all aspects, which is simply crushing.

Throughout the performance of the Timberwolves, Edwards did his best! In the 44-minute playing time, I scored 36+7 data and led the team all the time. No one can stop me in the backcourt! However, other Timberwolves players performed badly, especially the inside, which was completely exploded!

Timberwolves are luxurious insiders with Downs+Gaubert, which can be said to be 400 million insiders! And the result? Facing Jokic, the two men were not only at a disadvantage in rebounding, but also in inside attack. The team’s 400 million inside line was useless on the court, which was the main reason for the team’s loss.

After the game, George Karl, a senior coach of NBA, said: The Nuggets will complete the sweep, and the Timberwolves, a rotten team, must be torn down.

The timberwolves must be torn down, which is true! In recent seasons, the Timberwolves have won the first place and the second place, and the team has gathered stars such as Wiggins, Downs and Butler, but what happened? The team has been rebuilt, but it has never been effective. Last season, the 8-for-1 exchange for Gaubert became a complete joke. The players of this team have problems, and the team culture also has great problems.

For the Timberwolves, the core that the team can rely on, and the core that is worth cultivating, is only Edwards. Cultivate Edwards well and build a lineup around him. The team still has a chance to rise.

The 2023 Guizhou Tongren Fanjingshan Marathon was successfully completed, and more than 5,000 people ran passionately.

From: People’s Network-Guizhou Channel

People’s Daily Online, Tongren, April 23 (Chen Jiequan) On April 22, 2023, Guizhou Tongren Fanjingshan Marathon started. More than 5,000 runners from home and abroad gathered at Fanjingshan Smart Track to run "Fanshan Water Purification" and experience national fitness.

According to reports, the theme of this event is "Fanshan Water Purification and Wisdom Leading", and two projects, full marathon and half marathon, have been set up. After fierce competition, Ethiopia’s AmanKadiBulli and HiretJemberuGirma won the men’s and women’s half marathon respectively, while domestic athletes Yin Shunjin and Zhang Ting won the men’s and women’s full marathon respectively.

It is worth mentioning that the full marathon men’s and women’s champions and the half marathon men’s and women’s champions all broke the track record of Fanjingshan Marathon.

It is understood that Fanjingshan Smart Track is the first fully enclosed track in China that can host the A2 marathon of China IAAF. It has been selected into six typical smart fitness trail projects in China, and has the timing system certified by IAAF, which can realize the track data, visualization and intelligence. In addition, the track is also equipped with intelligent facilities such as running light belt, automatic induction bathing system, intelligent AED rescue station and intelligent heart rate column, which can hold bicycle, marathon, roller skating and iron third-class competitions and national fitness events.

The starting point of the track is located in Baguanxi, Bijiang District, and the ending point is located in Lianghekou, jiangkou county. One end is connected with Fanjing Mountain, a world natural heritage, and the other end is connected with Zhongnanmen, a national night cultural tourism consumption gathering area. The total length of the track is 43.742 kilometers, passing through 24 villages and 39 bridges, stringing together the "most beautiful scenery" of Baili Jinjiang.

In recent years, relying on the unique ecological advantages and tourism resources, tongren city has vigorously developed mass sports, competitive sports and sports industry with marathon and other sports events as the carrier, and built a number of influential brand events such as Fanjing Mountain Marathon, Fanjing Mountain Mountaineering Competition, Road Cycling Race around Fanjing Mountain and China Dragon Boat Open.

At present, tongren city is making great efforts to create a fitness environment that people are satisfied with, and making Fanjingshan Track a "sports destination" integrating rural revitalization, outdoor sports, sports events and sightseeing.

Sun Minghui superstar ball, Hu Jinqiu’s second attack king, Yi Jianlian scored 3 points, Guangdong did not cry.

In the 2022-2023 season, all the top four players in the CBA League playoffs were produced. In the 8-to-4 game, Zhejiang Dongyang (Guangsha) men’s basketball team lost the first series, but returned to the home game G2 to win the battle of Tianwangshan, the deciding game G3 was a life-and-death battle, and Ma Shang nemesis and Zhu Junlong, an important offensive line at both ends of Guangsha, successfully returned.

Throughout the life-and-death battle, Sun Minghui grabbed Jeff and was dragged in the fast break, which was an obvious violation of the fast break. The referee did not blow any penalty, and Sun Minghui’s injured arm was injured again; This led to a serious impact on Sun Minghui’s hand feeling, shooting 9 out of 27 and 3 out of 14, but the leader was the leader. Sun Minghui threw a superstar three-pointer at the last moment to kill the game and got 23 points, 5 rebounds and 8 assists.

Hu Jinqiu: How to evaluate this tough guy in CBA? When fighting for rebounds, I suffered a knee injury, but after a simple treatment, I returned to the stadium with an injury. You know, when Hu Jinqiu came off the court, Guangdong played a wave of 10-0; Hu Jinqiu became the anchor of Guangsha men’s basketball team, scoring 16 points and 22 rebounds, and Hu Jinqiu was the first and second offensive player in the league.

Zhao Jiaren: 4 out of 5 scored 3 points, and the audience scored 18 points. It was his rise and play that made Guangsha’s front line thicker and became a surprise soldier of Guangsha men’s basketball team.

Zhu Junlong: Sending opponents hot pot continuously, aiming at Ma Shang’s rhythm breakthrough, can effectively protect the frame and reduce Ma Shang’s offensive efficiency. Although he scored 11 points and 8 rebounds, Zhu Junlong is the key gentleman in Guangsha’s life-and-death battle;

Yi Jianlian: Is this his swan song? 3 points and 7 rebounds, 25% shooting percentage and 0% shooting percentage.

Jeff: The short board is serious. Although he has the defense of nanny searching, bathing and nursing, he lets his opponent shoot unscrupulously on his head, getting 5 points in 30 minutes, shooting 2 out of 10, 9 out of 3, and such a guard league catches a lot;

Zhao Rui: Forget it. He scored 7 points, 6 rebounds and 10 assists in 31 points, and made 3 of 14 shots and 1 of 4 of 3 points. It is predicted that the trade will come soon.

Post-game interview

Wang Bo: After winning the last game, the team’s fighting spirit was high, and it began to fight from the first minute.

Du Feng: I don’t want to end the league in this way. Everyone worked very hard. Many young players made mistakes that they shouldn’t have made, and they started badly. I hope everyone knows the pain of failure after growing up!

Millions of black powder can’t be black! To save Rome by himself, Mourinho is still a world-class player and is expected to return to Real Madrid.

At the end of 2019, Ancelotti left Naples and was soon re-employed in Everton, Premier League. A generation of famous coaches can only bow to small clubs. At that time, many people thought that his coaching career was basically like this.

To the surprise of many people, in the summer of 2021, Real Madrid took out the termination money and poached Ancelotti from Everton. A year later, An Shuai, wearing sunglasses and holding a cigar, led the whole team of Real Madrid to tour Madrid by an open-top bus to celebrate winning the 14th Champions League trophy in the team’s history.

Earlier this year, some media broke the news that the Brazilian Football Association intended to invite Ancelotti to take charge. A handsome man is a handsome man. Whenever you think he is dying, he can always give you a little surprise.

Mourinho’s trajectory in the past two years is actually a bit like that of Ancelotti. Some people think that coaching Tottenham Hotspur and Rome is the low point of his coaching career, but his achievements in Eternal City have hit many skeptics’ faces.

In Italy, there are far fewer media reports on Mourinho than in England. He is not impeccable, but the outside world usually regards him as a problem solver, not a problem maker. Italy respects Jose Mourinho, and his position is unparalleled among today’s Serie A coaches.

In 2010, Mourinho led Inter Milan to win the Triple Crown and left Serie A.. From then on until his return, the Italian club never won the European championship.

Last season, Mu Shuai broke the championship drought. Some people-especially Lazio executives-may say: What kind of honor is the Europa League?

But there is an Italian proverb that says words are light and will be blown away by the wind. The trophy is real. It’s the first championship trophy in Rome in 14 years. This trophy is very important for Roman fans who are eager to celebrate.

Mourinho helped Roman fans regain their pride and confidence. They returned to the Olympic Stadium in droves, and tickets for every game in Rome were sold out. Today, Mourinho has a supreme position in the hearts of Roman fans, which fills the gap left by Totti’s retirement to some extent.

Mu Shuai is in high spirits, but the club is crushed to death by FFP and can’t afford to meet his requirements for strengthening the lineup. If Mourinho finally leaves Rome because of this, it will be hard for fans to accept.

The hole dug by Meng Qi was too big, and Rome was absent from the Champions League all the year round, so the financial situation was extremely difficult. This season, several reinforcements they brought in-Dibala, wijnaldum, Ma Diqi and Belloti-were either visa-free or rented.

"(This season) only Sampdoria and Lecce spend less than us." Mourinho said. Winter window, Rome sold Zaniolo; Summer window, they have to continue to sell people to cash out.

However, Rome’s record has not declined. Last season, they were the sixth in Serie A; At present, they rank fourth in Serie A standings, three points ahead of Milan, which ranks fifth. Yesterday, in the second round of the Europa League quarter-final, they played with great excitement and made a strong reversal of Feyenoord and advanced.

In the last round of Serie A, Juve and Inter both lost, and Milan was tied by Bologna. Mu Shuai led the team to win Udinese 3-0, and grabbed the precious 3 points. Young Bolai started the game and Abraham came off the bench to end the scoring drought. Mourinho is really a master in balancing the league and the European war.

This year, Rome has completed 13 clean sheets in various competitions, and Mourinho has put his own brand on this team. They won’t lose easily, but they can also fight hard, beat Juventus and Inter Milan, and chase after two goals in the San Siro to draw Milan.

Last week, Cassano, an old Roman general, criticized Mourinho’s football as ugly, saying that he won the championship because of his platform and luck.

After that, Mu Shuai personally demonstrated to the old department how to fight: "Cassano played in the three clubs I coached, at different times." In Madrid, everyone only remembers his jacket. In Rome, he only won the Super Cup once, and he didn’t even play in that game. You all know what I have achieved at Real Madrid, Rome and Inter Milan. "

Mu Shuai’s team is very similar to him and very aggressive. Players question every decision of the referee and often fly with a yellow card. The whole coaching staff is not easy to mess with. Mu Shuai and other coaches have got 11 red cards this season! Recently, he recreated the classic handcuff gesture of Inter Milan, suggesting that someone was targeting himself.

Rome has hardened, and most Roman fans are satisfied with it. Mourinho also caught the "mole" in Rome, but it was different from that in the Premier League-afterwards, the players still served him and respected him, and the team continued to make progress.

Mourinho also had dark moments in Rome-for example, he was killed by Lazio this season and put on any other coach, which was a disastrous result. However, the fans and the team still support Mu Shuai.

Will he stay in Rome in the future? Mu Shuai himself has never expressed his position. Recently, berardi, former CEO of Rome, said he believed Mourinho would stay with the team.

"That’s what he said," Mourinho responded. "According to the contract, I still have one year. That’s the case. Football is football. Sometimes the contract is not the most important thing. "

Whether Mourinho can stay in the team depends on how Rome’s final results are this season and what plans the club has for the new season. But now Mu Shuai’s "market" is bullish again, and his wait-and-see attitude is understandable.

Both Real Madrid and PSG may have to change coaches, and florentino likes to "go back to the grass" when choosing coaches. Like Ancelotti the year before last, Mourinho also has a chance to return to the giants. Don’t talk about a comeback, Mu Shuai has always been Mu Shuai.

Cruel, goodbye Guardiola! It’s hard to keep a salary increase of 3 million even if it’s true and it’s a dream.

As the true core of Manchester City, the B-seat has a great position and role in the midfield. Guashuai has been forbearing not to let B go, and he also understands his role in the team. However, the Manchester City true nuclear continued to make trouble this season, which made Guashuai feel that the twisted melon is not sweet. In the interview, he also said: "If a player wants to play in another club, he won’t really keep on letting go, and he will respect the player’s ideas." Therefore, if Barcelona send an offer that is in line with the psychological price of Manchester City, the B seat can basically leave Manchester City to realize his dream of playing for Barcelona.

The Asian Cup is crazy again: Vietnam scored 11-0, the national football team broke the 9-year dilemma, and the sword refers to the World Youth Championship.

The Asian Cup is crazy again: Vietnam scored 11-0, the national football team broke the 9-year dilemma, and the sword refers to the World Youth Championship.

Text/Bin Shaokan Autumn (beginning) March, just as the Asian Football Championship started. The men’s soccer team participated in Uzbekistan U20 Asian Cup; It also brought many football festivals to Asian fans; A few days ago, the Asian Cup was crazy. First of all, Vietnam won two consecutive victories in the men’s soccer group match, beating Australia and Qatar. Unfortunately, they finally did it. Unfortunately, he was out again. Although he scored 6 points, he still couldn’t advance to the group stage.

In the first Asian Cup qualifiers of women’s football, the Australian women’s football team played crazy, beating Guam 13-0 and the China women’s football team beating the Filipino women’s football team 6-0; Another 11-0 victory hit the Singapore women’s football team hard. Although in the past, Vietnamese women’s football team was recognized as a weak team, with the development of Vietnamese football, their men’s and women’s football teams have risen a lot. In the future, they are bound to become the China team. Another new patient.

In terms of men’s soccer in China, in the group stage, 3 matches, 1 win, 1 draw, 1 loss and 4 points were accumulated. In the last round, thanks to the Japanese team’s victory over Saudi Arabia, the China men’s soccer team finally qualified in the group stage and reached the Asian Games. The top 8 in the youth competition, and that record also broke the dilemma of the youth national team for many years and returned to the top 8 seats after 9 years.

Judging from the overall process of the group stage, although the performance of China Men’s Football Team is remarkable, it does not have much advantage in the scene. Even against Kyrgyzstan, the weakest team in the group, the passport control organization of national youth players is completely at a disadvantage, and beating Saudi Arabia 2-0 is also a complete upset. In this game, the possession rate is as low as less than 30%. However, the game focuses on results. And then winning the bus is also commendable.

After the China men’s soccer team qualified, they also fell into an extreme situation. In other words, the South Korean team was the first to be criticized in the knockout. There are too many opportunities for men’s soccer in China. For China men’s soccer team, there is no way out. They can only fight hard to reach the top four, reach the top four of the Asian Youth Championship and win the World Cup. Tickets for the tournament, so the goal of China Men’s Football Team in this Asian Youth Championship is to beat the World Youth Championship with all one’s strength.

Bold! Ma Jing’s celebrity burst into controversy, VAR broke the double arrogant marketing, and C Ronaldo missed the grand prize from then on.

Since the VAR technology has been widely used in football, the voices of doubt have been one after another. Some people think that VAR makes the football game fragmented, which makes football lose a primitive aesthetic feeling, and even puts the manipulation of the game on the table. After all, when to watch or not to watch it is decided by the referee team, and things that are misjudged after watching it are sometimes staged in the Premier League. There is also a view that in most of the time, VAR still ensures the fairness and justice of the game, with less misjudgments and safeguards the interests of small and medium-sized teams. At least for Futre, a famous Atletico Madrid, VAR brings more positive aspects.

Indeed, considering the identity of Atletico Madrid, Futre is naturally a staunch supporter of VAR. At the peak of Atletico Madrid, they had at least one chance to win the Champions League, and this time the most likely opportunity was destroyed by Ramos’ offside goal. If there was VAR technology at that time, the first Champions League champion of Real Madrid in the three consecutive years would have ceased to exist. Of course, during the period of Real Madrid’s hegemony, because there was no VAR, there were many profits. In the game against Bayern, Luo Kaiyue, a notorious football stalk, was even born.

When he was a guest in the football column of O JOGO recently, Futre complained about the performance of the referee in Real Madrid’s two Champions League finals. He also talked about the recent referee incident in Barcelona. He said: "On the issue of referees, Real Madrid is the club with the least right to make irresponsible remarks about other teams. If Real Madrid asks La Liga officials to investigate the consulting fees paid by Barcelona to referees, then I suggest that all clubs in Europe should ask UEFA to judge the referees who have hosted Real Madrid’s Champions League matches.

In addition to this provocative speech, Futre also talked about some opinions on VAR. He believes that this technology is undoubtedly making football more fair, and it can provide some protection for the interests of small and medium-sized teams and reduce human errors caused by referees. Although the misjudgment still exists in the presence of VAR, the penalty made through VAR is correct most of the time, and these techniques significantly reduce the situation of benefiting from offside goals. Futre also said that if the VAR technology can be used as soon as possible, then the offside goals of Ramos and Cristiano Ronaldo in the Champions League should be cancelled.

Speaking of the performance of Messi and Cristiano Ronaldo in this World Cup, he is not optimistic that Cristiano Ronaldo will continue to play for the national team. He said: "Cristiano Ronaldo is a very good player, but the retrogression brought by age is inevitable. His mistakes are increasing every year, such as offside. Frequent offside is not the expression of goal desire, but the degradation of body and consciousness. With the capture of millimeter accuracy VAR, C Ronaldo’s offside times will only increase, but he is always at the forefront. He needs more offside to get a single shot. "

"Messi is not the same type of player. Messi has become more comprehensive. He is very smart. Messi is not a comparable object in terms of position or ability. However, Cristiano Ronaldo became a complete opportunist. The appearance of VAR and the decline of his body made his previous scoring ability unsustainable. After leaving La Liga, Cristiano Ronaldo won less honor. He was also replaced by players such as Mbappé in the competition for the highest honor in football, but Messi was still himself, and he was always compared by others. "

It is worth mentioning that Futre is not a rat. He is one of the legendary Portuguese superstars, the legendary winger of the national team, once the idol of Figo, and won the European Silver Ball Award in personal honor. He is a supporter of Messi. In this season’s Champions League match between Benfica and Paris Saint-Germain, Futre personally visited Messi through Campos’ relationship. He not only made a gesture of worship, but also hugged and took a photo with Messi, and finally asked for his autograph.

0-9 to 1-0, revenge! The penultimate madness of the Premier League: finally beating Liverpool and ending the seven-year wait.

At 20:30 on March 11th, Beijing time, in the 27th round of the Premier League, Salah missed a penalty and Billing scored the only goal in the game. In the end, Liverpool lost to Bournemouth 0-1 away and swallowed the first defeat in nearly 6 rounds.

Before this campaign, Liverpool scored 13 points in 5 rounds, 4 wins and 1 draw, and rushed to the fifth place in the league, only 3 points behind Tottenham Hotspur. They just washed Manchester United 7-0 at home in the last round. If they can score all three points from Bournemouth in this round, they will temporarily overtake Tottenham on goal difference and rise to the fourth place in the Premier League. Bournemouth lost 11 games in the last 15 rounds, only won twice, ranking the bottom of the Premier League with 21 points in 25 rounds.

In the first leg, Liverpool beat Bournemouth 9-0 at home, setting a record for winning the biggest score in the Premier League. Moreover, Liverpool have won seven consecutive victories against Bournemouth, during which they kept six clean sheets. The total score of these seven games reached a disparity of 28-1.

Who would have thought that all kinds of data predicted that Liverpool should take Bournemouth lightly, but in the end this round broke out with a 0-1 upset. For Liverpool, after losing these three points, it was doomed to not return to the top four after this round, but Burnley, who got the key three points, instantly overtook West Ham United, Leeds United, Everton and Southampton, not only got rid of the bottom of the league, but also escaped from the relegation zone and rose to 16th place. This is the first time that Liverpool lost to Bournemouth in the past seven years. The last time they lost to Bournemouth, they lost 3-4 away in December 2016.

Game review-

In the 29th minute, Ouattara made an inverted triangle cross from the bottom of 1V2 on the right, and scored a goal from Bilin Middle Road, with Bournemouth leading 1-0.

In the 69th minute, jota made a point, Salah took a penalty kick and flew wide, but Liverpool missed the equaliser and lost 0-1.

How to improve the navigation accuracy of autonomous robots? Artificial intelligence: strengthen machine learning!

Robot navigation has become more and more advanced in recent years, but in very crowded environments, such as public areas or roads in urban environments, most robots still cannot navigate accurately. In order to be widely used in smart cities in the future, robots need to be able to navigate reliably and safely in these environments without colliding with humans or nearby objects.

Image source: Martinez-Baselga, Riazuelo & Montano

The collision trajectory of the robot trained by standard exploration strategy (left) and the successful trajectory of the robot trained by intrinsic reward in the same scene.

Researchers from university of zaragoza and Aragon Institute of Engineering recently proposed a new method based on machine learning, which can improve robot navigation in indoor and outdoor crowded environments. This method is used inarXivAccording to a paper published in advance on the server, it is necessary to use intrinsic rewards, which are essentially "rewards" that AI agents get when they perform behaviors that are not strictly related to the tasks they try to complete.

Autonomous robot navigation is an unresolved problem, especially in unstructured and dynamic environments, robots must avoid colliding with dynamic obstacles and achieve their goals.

Facts have proved that the deep reinforcement learning algorithm has high performance in success rate and time to reach the goal, but there are still many places to be improved.

The method introduced by Martinez Baselga and his colleagues uses intrinsic rewards, aiming at increasing the motivation of agents to explore new "states" (i.e. interactions with their environment) or reducing the level of uncertainty in a given scenario, so that agents can better predict the consequences of their actions.

In their research background, researchers specially use these rewards to encourage robots to visit unknown areas in their environment and explore their environment in different ways so that they can learn to navigate more effectively over time.

Compared with the same algorithm with ICM (intrinsic reward), the training index of the most advanced algorithm.

Most deep reinforcement learning for crowd navigation focuses on improving the processing of network and robot perception.

My method studies how to explore the environment during training to improve the learning process. In training, the robot does not try random movements or optimal movements, but tries to do what it thinks it can learn more from them.

The researchers evaluated the potential of using intrinsic rewards to solve robot navigation in crowded spaces in two different ways. The first one integrates the so-called Intrinsic Curiosity Module (ICM), while the second one is based on a series of algorithms called Efficient Exploratory Random Encoder (RE3).

The researchers evaluated these models in a series of simulations, which were run on the CrowdNav simulator. They found that their two methods of integrating intrinsic rewards are superior to the most advanced navigation methods of crowded space robots developed before.

In the future, this research can encourage other robotics experts to use intrinsic rewards when training robots to improve their ability to cope with unforeseen situations and move safely in a highly dynamic environment.

In addition, the two models tested based on intrinsic rewards will soon be integrated and tested in real robots to further verify their potential.

The results show that by applying these intelligent exploration strategies, the robot can learn faster and the final learning strategy is better. And they can be applied to existing algorithms to improve them.

In the next research, it is planned to improve the deep reinforcement learning in robot navigation to make it safer and more reliable, which is very important for using it in the real world.
