In tennis tournaments, momentum, a critical yet elusive phenomenon, reflects the dynamic shifts in performance of athletes that can decisively influence match outcomes. Despite its significance, momentum in terms of effective modeling and multi-granularity analysis across points, games, sets, and matches in tennis tournaments remains underexplored. In this study, we define a novel Momentum Score (MS) metric to quantify a player's momentum level in multi-granularity tennis tournaments, and design HydraNet, a momentum-driven state-space duality-based framework, to model MS by integrating thirty-two heterogeneous dimensions of athletes performance in serve, return, psychology and fatigue. HydraNet integrates a Hydra module, which builds upon a state-space duality (SSD) framework, capturing explicit momentum with a sliding-window mechanism and implicit momentum through cross-game state propagation. It also introduces a novel Versus Learning method to better enhance the adversarial nature of momentum between the two athletes at a macro level, along with a Collaborative-Adversarial Attention Mechanism (CAAM) for capturing and integrating intra-player and inter-player dynamic momentum at a micro level. Additionally, we construct a million-level tennis cross-tournament dataset spanning from 2012-2023 Wimbledon and 2013-2023 US Open, and validate the multi-granularity modeling capability of HydraNet for the MS metric on this dataset. Extensive experimental evaluations demonstrate that the MS metric constructed by the HydraNet framework provides actionable insights into how momentum impacts outcomes at different granularities, establishing a new foundation for momentum modeling and sports analysis. To the best of our knowledge, this is the first work to explore and effectively model momentum across multiple granularities in professional tennis tournaments.

The US Open tennis tournament is using IBM's Watson artificial intelligence (AI) software to provide fans with automated video match highlights. IBM has developed a tool, known as Cognitive Highlights, as part of its new Watson Media applications. The system can analyse various aspects of the match video footage, such as the reaction of the players and the crowd, to identify which parts of the match are the most important. The aim is to help the video production team, which otherwise has to manage camera shots from multiple courts and manually select highlights. You forgot to provide an Email Address.

If you didn't think game day could get any better, get ready for robots. Two tech giants in the field of cognitive technology have recently announced plans to bring artificial intelligence to major international sports events. International Business Machines Corp. will partner with the Wimbledon tennis tournament, which starts July 3, while Intel Corp. will introduce a host of new technologies at the 2018 Olympic Games in South Korea. IBM will exercise a range of its AI abilities throughout the London-based tennis tournament. The company's signature AI platform, Watson, will help visitors track the most nail-biting matches and automatically tape video highlights of the event, IBM said in a statement.

Wimbledon's famous All England Lawn Tennis and Croquet Club, bedecked in the iconic purple and green and overflowing with Ivy, flowers and generations of tradition might, at first look, seem like a strange place to be contemplating how technology and sport have become such familiar bedfellows. And yet this most traditional of sporting environs is embracing technology on a whole host of levels, whilst maintaining the dignity and history as the home of tennis. Mick Desmond, the AELTC's commercial and media director explained that there was an "alchemy" in the balance of seeking what's new and innovative whilst understanding and enhancing what makes this most famous of tennis tournaments great. "We look at what's true in our brand in terms of the all-white dress code, the grass courts and the strawberries and cream, and as an event we do transcend the sport. We look at the things that make us special and we amplify them. "But in the digital realm particularly we can be very innovative and push the boundaries… whilst still enveloped in a Wimbledon way." This intent, according to former England cricketer and academic, Ed Smith, is not as new as many might think - insisting that embracing the latest technology has actually been at the heart of sport's development. "If you think about sport as we now play it, it's rested on a series of technological evolutions," he insists, taking us on a whirlwind tour of innovation, from lawnmowers to the iPhone via vulcanized rubber and, of course the impact of sport in the media. "The year 1923 brought the moment that changed sport forever - a radio station in New York saying we're going to put every second of the World Series on air.
