Prediction of Football Match Results Based on Edge Computing and Machine Learning Technology

With the rapid development of artificial intelligence, various machine learning algorithms have been widely used in the task of football match result prediction and have achieved certain results. However, traditional machine learning methods usually upload the results of previous competitions to the cloud server in a centralized manner, which brings problems such as network congestion, server computing pressure and computing delay. This paper proposes a football match result prediction method based on edge computing and machine learning technology. Specifically, we first extract some game data from the results of the previous games to construct the common features and characteristic features, respectively. Then, the feature extraction and classification task are deployed to multiple edge nodes.Finally, the results in all the edge nodes are uploaded to the cloud server and fused to make a decision. Experimental results have demonstrated the effectiveness of the proposed method.

Small-sided games do not replicate all external and internal loads of a football match-play during pre-season: A case study

This study investigated the differences in external and internal load during pre-season training sessions carried out with different SSGs and a friendly match in top-class professional football players. The study was conducted over a full pre-season. Participants were 9 male top-class professional football players (25 ± 5 years; 74 ± 8 kg; 177 ± 8 cm). The following variables were measured: training session duration (min), average heart rate (bpm), total distance (m), distance covered per minute (m/min), the total number of accelerations > 2.5 m/s2, number of accelerations > 2.5 m/s2 per minute, average distance of accelerations (m), the average value of acceleration (m/s2). One-way ANOVA was performed to analyze the variance of all evaluated variables. No differences were found in the average accelerations (m/s2) (0.128) among all the training formats. Moderate differences were found in number of accelerations > 2.5 m/s2 per minute (η2 = 0.396, moderate effect) and average distance of accelerations (η2 = 0.545). Strong differences were found in HR (η2 = 0.788, large effect), total distance (η2 = 0.797, strong effect), distance per minute (η2 = 0.775 strong effect), total number of accelerations > 2.5 m/s2 (η2 = 0.699 strong effect). Significant correlations were found just for the number of accelerations > 2.5 m/s2 and the number of accelerations > 2.5 m/s2 per minute with the 4v4, 8v8 and the FM (r = 0.828–0.890, r2 = 69% – 79%; p < 0.01). External and internal loads differ across different SSGs and a FM during the pre-season training sessions.

A big data analysis of Twitter data during premier league matches: do tweets contain information valuable for in-play forecasting of goals in football?

Data-related analysis in football increasingly benefits from Big Data approaches and machine learning methods. One relevant application of data analysis in football is forecasting, which relies on understanding and accurately modelling the process of a match. The present paper tackles two neglected facets of forecasting in football: Forecasts on the total number of goals and in-play forecasting (forecasts based on within-match information). Sentiment analysis techniques were used to extract the information reflected in almost two million tweets from more than 400 Premier League matches. By means of wordclouds and timely analysis of several tweet-based features, the Twitter communication over the full course of matches and shortly before and after goals was visualized and systematically analysed. Moreover, several forecasting models including a random forest model have been used to obtain in-play forecasts. Results suggest that in-play forecasting of goals is highly challenging, and in-play information does not improve forecasting accuracy. An additional analysis of goals from more than 30,000 matches from the main European football leagues supports the notion that the predictive value of in-play information is highly limited compared to pre-game information. This is a relevant result for coaches, match analysts and broadcasters who should not overestimate the value of in-play information. The present study also sheds light on how the perception and behaviour of Twitter users change over the course of a football match. A main result is that the sentiment of Twitter users decreases when the match progresses, which might be caused by an unjustified high expectation of football fans before the match.

COVID-19 Diffusion Before Awareness: The Role of Football Match Attendance in Italy

Anecdotal evidence suggests that football matches may have played a role in the spread of COVID-19 all over Europe. Nevertheless, from a scientific point of view, the impact of football matches on the spread of COVID-19 remains unclear. In this paper we study, via a quantitative analysis, the case of Italy, a country badly affected by COVID, and one where attending football matches is very popular. We consider the impact of matches played in January and February 2020 on the dynamic of the pandemic in March and April the same year. Our results, which consider all levels of Italian professional football, and the highest level of amateur football, show that matches played in January and February had an impact on the evolution of the pandemic in March and April. These results suggest that great care must be taken before considering re-opening stadia.

The Level Of Anxiety’s Referees Of Langsa (Football Association Of Indonesia) When Enforcing The Laws Of The Game During A Match

Football is a popular sport that is loved by all levels of society and throughout the world. A football match always engages a referee who enforces the game to oversee the course of the game consisting of the head referee and assistant referee. This article discusses the level of anxiety of the C-3 soccer referee at the PSSI Askot Langsa City, which amounted to 26 people. The research method used is descriptive quantitative with a survey approach. This study was to figure out information on the anxiety level of the C-3 referee while leading the match; the results showed 17 referees with a percentage of 65% in the high anxiety category and nine referees with a portion of 35% in the very high category. Factors that affect the referee's anxiety are the audience pressure factor. The high atmosphere of the match when the home team is competing and the human error factor from the referee itself is appeared because the referee hesitates in making decisions so that the same mistakes are repeated by head referee and assistant referee during a match underway.

Research and application of constructing football training linear programming based on multiple linear regression equation

Based on the factors affecting sports performance, from a more comprehensive and broad perspective, after consulting the literature, 52 factors that affect the outcome of football matches are selected, including technology, tactics, physical fitness and referees’ penalties. By watching the video of the game, 52 influencing factors of 200 games and 400 teams were counted. The original data was statistically processed with correlation analysis and multiple linear regression analysis, and the statistics of the 26 European Cup games were substituted into the winning formula. To verify the scientific nature and objectivity of the formula, we aim to ascertain the core factors in the winning factors of a football game and the quantitative relationship between these factors and the result of the game, so as to provide a certain reference for football training, game analysis and scientific research. The technical and tactical ability of individuals and teams is the core competitive ability factor that affects the result of the game; from a single factor, 15 factor indicators have a significant impact on the result of a football match; on the whole, 10 factor indicators have a significant effect on the result of a football match. In addition, there is a certain quantitative relationship between these influencing factors and the results of the game; empirical evidence shows that the football game winning formula has a certain degree of science and objectivity.

Influence of Football Match-Play on Isometric Knee Flexion Strength and Passive Hip Flexion Range of Motion in Football Referees and Assistant Referees

The aim of this study was to examine the acute effect of officiating a football (soccer) match on isometric knee flexion strength and passive hip flexion range-of-motion (ROM) in referees and assistant football referees. Twelve referees (25.3 ± 3.3 years) and twenty-three assistant referees (25.1 ± 4.8 years) underwent measurements on isometric knee flexion strength and passive hip flexion ROM before and after officiating an official football match. Referees’ and assistant referees’ running patterns were monitored during the match using GPS technology. In comparison to pre-match values, referees reduced their isometric knee flexion strength (−12.36%, p = 0.046, Effect size [ES] = −0.36) in the non-dominant limb, while no significant differences were reported in the dominant limb (−0.75%, p = 0.833, ES = −0.02). No effect of the match was found in hip flexion ROM values in dominant (−4.78%, p = 0.102, ES = −0.15) and non-dominant limb (5.54%, p = 0.544, ES = 0.19). In assistant referees, the pre-to-post-match changes in isometric knee flexion strength (dominant limb −3.10%, p = 0.323, ES = −0.13; non-dominant limb −2.18%, p = 0.980, ES= 0.00) and hip flexion ROM (dominant limb 1.90% p = −0.816, ES = 0.13; non-dominant limb 3.22% p = 0.051, ES = 0.23) did not reach statistical significance. Officiating a match provoked a reduction in isometric knee flexion strength in the non-dominant limb of football referees, while no differences were reported in assistant referees.

Stadi Derby and the Securitization of Urban Public Space

Stadi Derby is a local football match played in Helsinki, Finland appreciated for its atmosphere and excitement. Simultaneously, the negative characteristics connected to the international football fan culture have become familiar also to those living in the capital area and especially in the surroundings of the stadium. The threat of violence is visible e.g. in the media coverage reporting about the derby. All this has also effect on the way the city dwellers experience the urban public space. In our article, we ask what kind of discourses can be found concerning the relationship between Stadi Derby and the right to public space and what kind of consequences i.e. reactions these discourses create among those city dwellers not involved in the football culture. In order to understand the ways these events and the media coverage over them have effect on urban dwellers we apply securitization theory. We look for speech acts from the media coverage and analyse the ways people respond to these speech acts through material produced via Facebook and a focus group interview. The division between insiders and outsiders to the football culture is clear: The outsiders feel distress, even fear, in consequence of media materials.

A Case Study of Sandplay Therapy for a Boy with Tic

Objectives: This study examined sandplay therapy in an elementary school boy with tic problems. The goal of the therapy was to reduce his tic problems by offering a free and protected space of sandplay therapy.Methods: The sandboxes were analyzed focusing on analytical psychology and theories of sandplay therapy using Turner (2005)’s content themes, which were the most comprehensive themes.Results: Seventy-seven therapy sessions were performed. The client showed a race car that was stuck in the sand and then rescued by forklifts in the initial phase of therapy (1-2, a race car stuck in the sand). In the intermediate phase of the therapy (3-70, struggle), he showed regression, meeting the opposites, victory of small animals, construction, and death. In the final phase of therapy (71-77, race, death II, adaptation to reality), he showed race, death, and adaptation to reality.Conclusion: The client who was entering adolescence saw life as a race. However, the race car that was moving toward masculinity was stuck in the sand. Therefore, the car was sent for repairs. In the middle of the therapy, the boy showed various fights, accidents, and construction. Lastly, there were deaths of an alligator and a bear. By showing a football match, the long journey of developing ego ended. During the therapy, archetypal patterns, such as regression to the primitive psyche, the journey of masculinity as a boy, and confrontation between good and bad, appeared. Sandplay therapy, in a free and protected space, relieved the client’s tic problems with improvement of his daily life. Thus, this study demonstrates the effectiveness of sandplay therapy.
