Optimal Playing Position Prediction in Football Matches: A Machine Learning Approach

By Kevin Sander Utomo Trianggoro Wiradinata

DOI: https://doi.org/10.5815/ijieeb.2023.06.03, Pub. Date: 8 Dec. 2023

Deciding optimal playing position can sometimes a challenging task for anyone working in sport management industry, particularly football. This study will present a solution by implementing Machine Learning approach to find and help football managers determine and predict where to place individual existing football players/potential players into different positions such as Attacking Midfielder (AM), Defending Midfielder (DMC), All-Around Midfielder (M), Defender (D), Forward Winger (FW), and Goalkeeper (GK) in a specific team formation based on their attributes. To aid in this identification process, it may be beneficial to understand how a player’s playstyle can affect where a player will be positioned in a team formation. The attributes used in facilitating the identification of the player position will be based on Passing Capabilities (AveragePasses), Offensive Capabilities (Possession, etc), Defensive Capabilities (Blocks, Through Balls, Tackles, etc), and Summary (Playtime, Goals, Assists, Passing Percentage, etc). The data that will be analysed upon will be scrapped manually from a popular football site that present football players statistics in a structured and ordered manner using a scrapping tool called Octoparse 8.0. Afterwards, the data that has been processed will be used to create a machine learning predictor modelled using various classification algorithms, which are KNN, Naive Bayes, Support Vector Machine, Decision Tree, and Random Forest ,coded using the Python programming language with the help of various machine learning and data science libraries, further enriched with copious graphs and charts which provides insight regarding the task at hand. The result of this study outputted in the form of the model predictor’s evaluation metric proves the Decision Tree algorithm have both the highest accuracy and f1-score of 76% and 75% respectively, while Naïve Bayes sits the lowest at both 69% accuracy and f1-score. The evaluation has prioritized validating and filtering algorithms that have overfitting in copious amounts which are evident in both the KNN and Support Vector Machine algorithms. As a result, the model formed in this study can be used as a tool for prediction in facilitating and aiding football managers, team coaches, and individual football players in recognizing the performance of a player relative to their position, which in turn would help teams in acquiring a specific type of player to fill a systematic frailty in their existing team roster.

Folding Bicycle Prospective Buyer Prediction Model

By Trianggoro Wiradinata

DOI: https://doi.org/10.5815/ijieeb.2021.05.01, Pub. Date: 8 Oct. 2021

The trend of bicycle exercise during the pandemic has resulted in increased sales and even scarcity of bicycle stock in some shops. The phenomenon has raised attention from both the bicycle industry and government to provide necessary responses toward the trends. Even though it is a trend, many prospective buyers are still confused about their choices. The types of bicycles that sell the most on the market are folding bikes, mountain bikes, and racing bikes. The research data were collected from 242 bicycle users who came from various bicycle communities in major cities of Java Island, Indonesia. Some of the predictors used were age, gender, height, weight, and cycling speed. The target variable is the type of bicycle whose data is categorical. Predictor variables consist of nominal and ordinal variables, so preprocessing needs to be done using Python's Sklearn library. To test the accuracy of the model, the data was broken down into training data and test data with a test size of 20%. Several methods are used to form a classification model, including K-NN, Naive Bayes, Support Vector Machine, Decision Tree, and Random Forest. The results of the classification model evaluation show that the Support Vector Machine and Decision Tree have the highest accuracy of 90%, while Naive Bayes has the lowest accuracy of 73%. The model formed can be a predictive tool for potential bicycle buyers in order to be able to choose the right type of bicycle.

The Role of Curriculum and Incubator towards New Venture Creation in Information Technology

By Trianggoro Wiradinata Tony Antonio

DOI: https://doi.org/10.5815/ijeme.2019.05.05, Pub. Date: 8 Sep. 2019

The number of entrepreneurs in Indonesia in 2017 has increased to 3.1%, which is a good development, compared to the previous years. Some of the factors that are suspected to contribute in this improvement are education and mentoring through various programs, including curriculum and incubator. Although it has increased, but this figure is still behind compared to neighbouring Indonesia's countries such as Singapore, Malaysia, and Thailand. Therefore, it is important to conduct an explorative study of the role of curriculum and incubator. This article will review the curriculum and incubator strategies that help increase the number of entrepreneurs, especially in the field of information technology in Indonesia. A qualitative comparison among several incubators, including Ciputra University approach discussed. This study found that the role of curriculum is to create a formal knowledge about ideation and process of start-up, incubator role is to provide physical co-working space while widen network resources. Another finding shows that there are some similarities and differences between industrial-based and university-based incubator. There are similarities in the resources, networking and guidance. The significance difference is in the curriculum since university has more time to guide but the student has lesser capacity compare to the industrial-based incubator start up, hence both experiences are strongly suggested to increase the success rate of Information Technology based Venture Creation.
