Sports Illustrated
''Sports Illustrated'' (''SI'') is an American sports magazine first published in August 1954. Founded by Stuart Scheftel, it was the first magazine with a circulation of over one million to win the National Magazine Award for General Excellence twice. It is also known for its annual Sports Illustrated Swimsuit Issue, swimsuit issue, which has been published since 1964, and has spawned other complementary media works and products. Owned until 2018 by Time Inc., it was sold to Authentic Brands Group (ABG) following the sale of Time Inc. to Meredith Corporation. The Arena Group (formerly theMaven, Inc.) was subsequently awarded a 10-year license to operate the ''Sports Illustrated''–branded editorial operations, while ABG Brand licensing, licenses the brand for other non-editorial ventures and products. In January 2024, The Arena Group missed a quarterly licensing payment, leading ABG to terminate the company's license. Arena, in turn, laid off the publication's editorial staff ...

Gambler
Gambling (also known as betting or gaming) is the wagering of something of value ("the stakes") on a random event with the intent of winning something else of value, where instances of strategy are discounted. Gambling thus requires three elements to be present: consideration (an amount wagered), risk (chance), and a prize. The outcome of the wager is often immediate, such as a single roll of dice, a spin of a roulette wheel, or a horse crossing the finish line, but longer time frames are also common, allowing wagers on the outcome of a future sports contest or even an entire sports season. The term "gaming" in this context typically refers to instances in which the activity has been specifically permitted by law. The two words are not mutually exclusive; ''i.e.'', a "gaming" company offers (legal) "gambling" activities to the public and may be regulated by one of many gaming control boards, for example, the Nevada Gaming Control Board. However, this distinction is not univers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NCAA Division I
NCAA Division I (D-I) is the highest division of intercollegiate athletics sanctioned by the National Collegiate Athletic Association (NCAA) in the United States, which accepts players globally. D-I schools include the major collegiate athletic powers, with large budgets, more elaborate facilities and more athletic scholarships than Division II and Division III as well as many smaller schools committed to the highest level of intercollegiate competition. This level was previously called the University Division of the NCAA, in contrast to the lower-level College Division; these terms were replaced with numeric divisions in 1973. The University Division was renamed Division I, while the College Division was split in two; the College Division members that offered scholarships or wanted to compete against those who did became Division II, while those who did not want to offer scholarships became Division III. For college football only, D-I schools are further divided into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basketball
Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular Basketball court, court, compete with the primary objective of #Shooting, shooting a basketball (ball), basketball (approximately in diameter) through the defender's Basket (basketball), hoop (a basket in diameter mounted high to a Backboard (basketball), backboard at each end of the court), while preventing the opposing team from shooting through their own hoop. A Field goal (basketball), field goal is worth two points, unless made from behind the 3 point line, three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (Overtime (sports), overtime) is mandated. Players advance the ball by boun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graph (discrete Mathematics)
In discrete mathematics, particularly in graph theory, a graph is a structure consisting of a Set (mathematics), set of objects where some pairs of the objects are in some sense "related". The objects are represented by abstractions called ''Vertex (graph theory), vertices'' (also called ''nodes'' or ''points'') and each of the related pairs of vertices is called an ''edge'' (also called ''link'' or ''line''). Typically, a graph is depicted in diagrammatic form as a set of dots or circles for the vertices, joined by lines or curves for the edges. The edges may be directed or undirected. For example, if the vertices represent people at a party, and there is an edge between two people if they shake hands, then this graph is undirected because any person ''A'' can shake hands with a person ''B'' only if ''B'' also shakes hands with ''A''. In contrast, if an edge from a person ''A'' to a person ''B'' means that ''A'' owes money to ''B'', then this graph is directed, because owing mon ...

Bayesian Network
A Bayesian network (also known as a Bayes network, Bayes net, belief network, or decision network) is a probabilistic graphical model that represents a set of variables and their conditional dependencies via a directed acyclic graph (DAG). While it is one of several forms of causal notation, causal networks are special cases of Bayesian networks. Bayesian networks are ideal for taking an event that occurred and predicting the likelihood that any one of several possible known causes was the contributing factor. For example, a Bayesian network could represent the probabilistic relationships between diseases and symptoms. Given symptoms, the network can be used to compute the probabilities of the presence of various diseases. Efficient algorithms can perform inference and learning in Bayesian networks. Bayesian networks that model sequences of variables (''e.g.'' speech signals or protein sequences) are called dynamic Bayesian networks. Generalizations of Bayesian networks tha ...

Diminishing Returns
In economics, diminishing returns means the decrease in marginal (incremental) output of a production process as the amount of a single factor of production is incrementally increased, holding all other factors of production equal ('' ceteris paribus''). The law of diminishing returns (also known as the law of diminishing marginal productivity) states that in a productive process, if a factor of production continues to increase, while holding all other production factors constant, at some point a further incremental unit of input will return a lower amount of output. The law of diminishing returns does not imply a decrease in overall production capabilities; rather, it defines a point on a production curve at which producing an additional unit of output will result in a lower profit. Under diminishing returns, output remains positive, but productivity and efficiency decrease. The modern understanding of the law adds the dimension of holding other outputs equal, since a giv ...

Elo Rating System
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess or esports. It is named after its creator Arpad Elo, a Hungarian-American chess master and physics professor. The Elo system was invented as an improved Chess rating system, chess-rating system over the previously used Harkness rating system, Harkness system, but is also used as a rating system in association football, association football (soccer), American football, baseball, basketball, pool (cue sports), pool, various board games and esports, and, more recently, Large language model, large language models. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for th ...
