Two consecutive defeats sent Manchester City to defend the title, and Arsenal ran for 11 months without success.

Nottingham Forest 1-0 Arsenal (war communiqué)

Titan sports’s all-media correspondent in Britain, Liu Chuan.

In the last round, Arsenal lost 3-0 to Brighton at home. The prediction given by the English media is that Manchester City will lock the league title after this round of game against Chelsea. However, at that time, the outside world obviously overestimated the current state of the arsenal. As a result, Arsenal, who took the lead on Saturday, lost to Nottingham Forest 0-1 away, not only "assisted" the latter to avoid relegation, but also completely sent Manchester City to the throne.

Arsenal have only won two games in the last eight rounds. The media bluntly said that as a champion team, the performance in the final stage was not even above the passing line. Arteta tried to change the formation in this game. Ben Wright, Kiviol and Gabriel partnered with three central defenders, while Zaka, Thomas and jorginho started in midfield. When the team was in a state of non-high oppression, Thomas retreated to the right defense line to participate in the defense. This strange change of formation has caused many English media to adjust their coverage of Arsenal’s starting formation several times after the opening. Pat neven, a famous Scottish player, said that he couldn’t understand this trial array at all. "You will find that quite a few players are in unfamiliar positions, especially when you find that neither side of Arsenal’s defense is a full-back, and the real left-back Thirny is sitting on the bench. You don’t know how he feels when he looks at Ki viol in his good position."

Arsenal quickly conceded the goal in the 19th minute, and Awoniyi, with Ramsdale attacking before and Gabriel chasing after, sent the ball into an empty net before the two men finished the attack, 1-0! The subsequent multi-angle slow motion shows that Gabriel actually put the shovel before Avonii’s foot and touched the ball, but this tackle made the ball refract to the arch of the Nigerian striker impartially, helping the opponent to push the ball comfortably into the empty goal.

The defeat in Nottingham was Arsenal’s first consecutive defeat in the league this season. Unlike losing to Brighton in the last round, they had nearly 90 minutes to change the situation when injury time was included in this game, but in the end, the gunman held 82% possession of the ball, but the audience only shot three shots. The actual injury time in the second half was as long as 8 minutes, and Nottingham Forest was almost torn by the pressure of relegation. Many home fans in the stands were afraid to look straight at the stadium after 80 minutes and chose to bury their heads and pray for the team.

Even in this case, Arsenal’s performance was criticized by the media for lack of urgency, as if they were the leading side. BBC reporter gary ross is puzzled by Arsenal’s slow pace. "Those who don’t know the score may think that Arsenal are leading 1-0 now and are patiently seeking the second goal to seal the victory. But the fact is that even the fans with good temper probably can’t accept the team’s withdrawal from the league title competition in this way. I’m afraid even Manchester City didn’t think of it, because after they beat Everton last Saturday, they were tied with Arsenal for the first time in quite some time, and the gunners actually collapsed immediately."

Even so, Arsenal fans who went out with the team still sang Super mikel arteta in the stands when the game was about to enter the injury time stage. Although the game is still not over, everyone seems to have accepted the reality that the championship will fall short in advance. Simon Stone, a famous BBC reporter, believes that Arsenal’s performance is still good throughout the season, but this time it is a monster-like terrible team that competes with them for the championship trophy. "You can hear the songs of Arsenal fans, and they still firmly support Artta, because in any case, they will all win the second place in the league with league points that were unimaginable at the beginning of the season. They have not been able to compete with Manchester City, but Arsenal is still the club closest to Guardiola’s terrorist team in the league."

With the final whistle of referee Anthony Taylor, Nottingham Forest successfully relegated, while Manchester City completed the great cause of three consecutive league titles and won five Premier League titles in the last six seasons. Some fans ridiculed that even Manchester City players probably didn’t expect the suspense of the league title to be announced so soon. "Considering the schedule of the last two weeks, after defeating Everton last week, Guardiola probably thought that Arsenal would beat Brighton first, narrow the gap at the top of the list to 1 point again, and then beat Nottingham Forest today, and rushed back to the top of the list briefly with the advantage of many games. Therefore, Gua Shuai’s schedule of winning the league within Manchester City is mostly around next Wednesday, that is, after the make-up match against Brighton. He may think that only then can they establish enough advantages in the standings to lock the league title. No one expected that Arsenal would lose two games in a row and take the initiative to go out. "

For Arsenal, this means that they have occupied the top spot for 248 days this season, but in the end they lost the title. This also set an embarrassing record for the top leagues in England: the non-champion team that stayed at the top for the longest time. Coach Artta first congratulated Manchester City for successfully defending the title, and then took the initiative to take the responsibility of losing. "We must first congratulate Manchester City for defending the title again, but for us, this is a sad day. The team should face the reality now. Today, we lost the ball first, and then we didn’t show enough excellent performance to turn the situation around. According to today’s game situation, even if we are given another three hours, we may get nothing. This is my responsibility and I will take the initiative to bear it. We have worked hard together for this (championship) for 11 months, but we haven’t done enough. This is football. The pain is very intense, but we must find a solution to improve the performance of the team as soon as possible. This season is not over yet, and there is still a harsh week ahead. "

As a famous player in Arsenal, Adams, the old captain of Arsenal, frowned after the game. He believed that the team eventually lost to the lineup gap with Manchester City. "Arsenal can only base itself on its own resources. When some (main) players decline, they obviously can’t come up with effective emergency alternatives. Of course, their overall performance this season has been excellent. Saka is likely to win the best young player award of the season, but by the end of the season, this feeling of falling apart is really embarrassing. "

Infrastructure for training AI to solve common problems

In order to train artificial intelligence models that can solve common problems, infrastructure is needed to provide support. These infrastructures are usually composed of hardware, software and tools to improve the efficiency and accuracy of model training. This article will introduce the infrastructure for training AI to solve common problems.

I. Hardware infrastructure

When training artificial intelligence models, it is usually necessary to use high-performance computing hardware to provide support. The following are several common hardware infrastructures:

  1. CPU: The central processing unit (CPU) is a general-purpose computing hardware, which can be used to run various types of software, including artificial intelligence models. Although the performance of CPU is relatively low, it is still useful in training small models or debugging.

  2. GPU: A graphics processor is a special computing hardware, which is usually used to process images and videos. Because of its highly parallel structure, GPU can provide higher computing performance than CPU when training artificial intelligence models, so it is widely used.

  3. TPU: Tensor processor is a kind of hardware specially used for artificial intelligence computing, developed by Google. The performance of TPU is higher than that of GPU, and it is suitable for large-scale artificial intelligence model training and reasoning.

Second, the software infrastructure

In addition to hardware infrastructure, some software tools are needed to support the training of artificial intelligence model. The following are some common software infrastructures:

  1. Operating system: Artificial intelligence models usually need to run on an operating system, such as Linux, Windows or macOS.

  2. Development environment: Development environment usually includes programming language, editor and integrated development environment (IDE) for writing and testing artificial intelligence models. Common development environments include Python, TensorFlow, PyTorch and Jupyter Notebook.

  3. Frames and libraries: Frames and libraries provide some common artificial intelligence model algorithms and data processing tools, making model development and training more convenient. Common frameworks and libraries include TensorFlow, PyTorch, Keras and Scikit-Learn.

Third, the tool infrastructure

In addition to the hardware and software infrastructure, some tools are needed to support the training of artificial intelligence models. The following are several common tool infrastructures:

Dataset tool: Dataset tool is used to process and prepare training datasets, such as data cleaning, preprocessing, format conversion, etc. Common data set tools include Pandas, NumPy and SciPy.

2 Visualization tools: Visualization tools are used to visualize the training process and results to help users better understand the performance and behavior of the model. Common visualization tools include Matplotlib, Seaborn and Plotly.

Automatic parameter tuning tool: The automatic parameter tuning tool is used to optimize the parameters of the model to improve the performance and accuracy of the model. Common automatic parameter tuning tools include Optuna, Hyperopt and GridSearchCV.
