Tennis is one of the most popular sports played in the world. Many researchers have worked in the fields of forecasting the outcome of tennis matches using past statistical data records. This paper mainly investigates the comparison between three different classifiers namely decision tree, multilayer perceptron and support vector machine. The research study aims to predict the result of tennis matches using eight UCI databases of grand slam tennis tournaments and evaluate the classification performance using various measures such as the root-mean-square error, accuracy, false positive rate, true positive rate, kappa statistic, recall, precision, and f-measure. All these performance measures confirm the supremacy of the decision tree classification …show more content…
The tennis prediction model is developed to evaluate the chance of winning match that the players will face. When a game is played, the result depends on many factors including the playing environment, player’s skill and past match results. Many approaches such as statistical data evaluation have been used so far. But predicting the theoretical outcome of tennis matches is a challenging task and has been a keen interest for many researchers. Indeed, enough scope is there for making significant improvement in the quality of prediction and the interpretation of results. The present research study basically aims to predict the outcome of a tennis singles match using past match records of the grand slam …show more content…
The artificial neural network [7] [8] [9] is a computational model inspired by human central nervous systems used to estimate or approximate functions that depends on a large number of unknown input data. In this model, we use multilayer perceptron (MLP) [10] [11] which is a feed-forward artificial neural network model that maps sets of input data elements considered as individual nodes on to a set of appropriate output data elements. An MLP contains multiple layers of nodes in a directed graph in which each of the different layers fully connected to the next layer. Also, each node is a neuron (or individual processing element) with a nonlinear activation function except for the input nodes. It uses a supervised learning method called backpropagation for training the neural network. Support vector machine (SVM) [12] is a supervised learning model that can analyze data and recognize patterns used for classification and regression analysis. The decision tree [13] [14] learning approach considers decision tree as a prediction model that is a tree with internal nodes as each decision and leaf nodes as the result of the decisions made. This approach can be used to analyze our result as each path from the root to leaf node represents a solution for our
In “Is the NBA Draft Looking at a Talent Drought in 2019? The Early Returns Aren’t Good” by Jeremy Woo, the author describes predictions made about the 2019 NBA draft class. The group does not contain much spectacular talent, which is causing draft scouts to think the class is inauspicious. Woo outlines the class’s talent problem by describing the skill of the players, the competition at big events, and the opinion of NBA scouts. The 2019 draft class does not have many stars that separate themselves from the others.
This book also consists the formulas of Pythagorean expectations, which is used on past seasons to predict the players and
In Matched the author, Ally Condie, uses mystery and character development to build intense drama between characters. When a member in the society turns 17 all the girls and boys in my society get their match, it is a match form outside their community, but Cassia got matched with her best friend Xander (he is from her community). When she looks at his profile another face pops up, and it was Ky. The author focuses on building a love interest between Cassia and Ky leaving drama between all three characters: Xander, Cassia, and Ky.
As well as to calculate who the better player is. This project is to help determine who the better basketball player is which is adhered through their career stats or opinion by people. The type of data that is going to be collected are the overall career stats from both players. Also, a survey consisting of 40 random kids. Hypothesis: The best player out of the two will be determined by a person’s opinion rather than career stats based off different types of data
Fantasy football fans will be scouring all the usual suspects for football facts, predictions, myths, legends and lies during the preseason. Not just because football fans are info junkies, but because they plan on trouncing their coworkers, neighbors, and in-laws in the next season of fantasy football leagues. Crazy fools that they are will probably find nothing but reams and reams of statistics. So unless they all received a PHD in statistical analysis during their drunken college years, they really wont be any further ahead then you my dear reader. Becuase, we are not going to be taking statistics here, instead we 're unveiling the deepest darkest secrets of winning football fantasy leagues.
The many things I have doubted have actually come true and I fear for the worst. Yes, it has been a while since I’ve last composed a note in this diary, but it is because I haven’t been sleeping well and trying to get a grasp on what has been happening. Additionally, it has gone around that there is a meeting being planned at the tennis court by the unruly third estate. Moreover, it does not sound good, and I think they are planning to do something harmful or deadly and I just hope my husband doesn’t interfere with the situation, for I care about him dearly and want nothing to happen to him.
Tennis is something that Haydn. Koushik, and Tyke all have in common. All 3 boys started playing at different times and discovered this sport in different ways, but they all are now a part of the Elkhorn High School Tennis team. Haydn started in 4th grade and he learned from his aunt and dad. Koushik started playing his freshman year because he used to play with his dad and decided to try it out.
The author did a good job at explain the four basic racquetball serves. He started by generally describing the primarily serving goal, pointing out that in order to win a 15 point game, at least 5 points should come from serves that were not returned by the opponent. After the brief introduction, the author provided clear and detailed information about each serve. He started by describing the serve Z and The Drive, which are attacking serves. I liked how he mentioned that these 2 serves should be tried at the first serving attempt because they are more complicated and therefore more likely to be a fault.

Great clinicians are not born they are created, they start from somewhere and they’ve made mistakes on their journey to success. During my time volunteering at the Maggie Coffey Memorial Tennis Tournament, I encountered many tennis players with a variety of complaints, such as: Achilles’ tendon pain, ulnar collateral ligament dysfunction, pinched nerve syndrome “Sciatica, etc. One of the challenges that I faced while observing the tennis players was discerning the appropriate clinical questions to ask in order to get to the possible root of the problem While interviewing the patient, I found myself stuttering and asking each of the patients the same general question although they each presented with different signs and symptoms. I feel that the area that came the easiest to me was conducting the basic active/passive range of motion and manual muscle testing on the patient, by conducting these tests, I could ensure that range of motion and muscle strength were not affected by the pain and symptoms reported.
As fans of the NBA, we 're always looking for more NBA knowledge. For the rhetorical analysis and insightful observations, the NBA website was critiqued and analyzed. The reason the NBA website exist is due to the fact it provides entertainment and information about the league. Using pathos, logos, and ethos; the website reaches out to everyone from athletes to loyal basketball fans.
