2.2. One-hot Encoding

One-hot encoding is a method to represent categorical data numerically [5]. It converts categories into binary vectors, where each category corresponds to a unique column with '1' or '0' values indicating the presence or absence of the category. This technique is valuable in machine learning. For instance, in a movie dataset where genres are encoded using one-hot encoding:

Original Data:

Movie A: Action, Adventure

Movie B: Romance, Drama

One-Hot Encoded:

Movie A: Action[1], Adventure[1], Romance[0], Drama[0]

Movie B: Action[0], Adventure[0], Romance[1], Drama[1]

This transformation allows for efficient analysis, such as personalized recommendations based on genres a user prefers, studying the impact of genres on ratings, and grouping similar movies using clustering algorithms.

The one-hot encoding provides us with a more comprehensive numerical representation of data, enabling the feasibility of various machine-learning methods and analyses. Here are three potential innovative analytical points utilizing such encoded data:

Prediction Models based on Developers, Platforms, and Genres:

Through one-hot encoding, we can employ developers, platforms, and genres as features to train machine learning models, predicting aspects like game ratings, user counts, etc. For instance, we can explore which specific developers, platforms, or genres correlate most with high-rated games. This aids in understanding the factors that might influence a game's success in the market.

Association Rule Mining:

Post one-hot encoding, association rule mining techniques can be employed to uncover patterns within the data. For example, we could discover certain platforms and genres that frequently co-occur, or that specific developers tend to produce popular games of particular styles. This provides insights into market trends and consumer preferences.

3. Data Analysis

3.2. Clustering

3.2.1. Introduction of K-Means

Given a dataset \( x=\lbrace {x_{1}}, {x_{2}}, ..., {x_{m}}\rbrace \) , where each \( {x_{i}} \) is an n-dimensional data point. Let \( C=\lbrace {C_{1}}, {C_{2}}, ..., {C_{K}}\rbrace \) be the K cluster centers. The goal of K-means is to minimize the sum of the distances between every data point and its assigned cluster center. Mathematically, this can be expressed as:

\( J(C, X)=\sum _{i=1}^{m}\underset{j=1,..., K}{min}{{‖{x_{i}}-{c_{j}}‖^{2}}} \)

where \( ‖ ‖ \) represents the Euclidean distance and C is the assigned cluster center to be updated. In each iteration, K-means performs two main steps. For each data point \( {x_{i}} \) , find the nearest cluster center \( {c_{j}} \) and assign \( {x_{i}} \) to that center. Then for each cluster center \( {c_{j}} \) , recompute it as the mean of all data points assigned to it.

3.2.2. Clustering Analysis

We conducted K-means clustering on the data using different quantities. Data clustering helps to divide a large dataset into meaningful groups, making it easier to understand the structure and characteristics of the data. Through clustering, we can identify patterns, trends, and correlations within the data, which aids in revealing the inherent properties of the data.

3.3. Linear Regression

Based on our dataset, we have determined that predicting the rating through Developers, Platforms, and Genres, or predicting the rating based on player-related information, holds the most significant potential value. After conducting extensive experimentation with various methodologies, we ultimately concluded that employing Platforms and Genres for multiple linear regression analysis is the most suitable approach.

After experimenting with various regression approaches, we observed that due to the diversity and randomness inherent in gaming market data, numerous lesser-known games could introduce significant uncontrollable variability into overall trend predictions. This rendered comprehensive forecasting nearly unattainable. Therefore, we made the decision to mitigate the impact of these random factors within our dataset. We employed an innovative approach called "top-labels".

“Top-labels” is the method we use to extract the key features of the data. After arranging the data in descending order of rating, we only allow one label to appear in the top 100 data that contain it. This method offers distinct advantages in gaming market analysis, as it effectively encapsulates the characteristics of various Platforms and Genres, while also providing insights into the current industry status based on label distribution density. Following the preprocessing using this approach, we achieved highly accurate prediction results through conventional linear regression techniques.

The model's performance can be gauged using several statistical metrics, among which the R-squared (R2) index and the mean squared error (MSE) stand out for their significance. In our analysis, the R2 value achieved was 0.6500. In layman's terms, this suggests that the model can explain approximately 65% of the variance in the dependent variable based on the independent variables provided. This is a noteworthy achievement, especially in the complex realm of gaming market dynamics, where numerous factors interplay. Further delving into the model's metrics, the reported MSE is 0.0784. This metric offers insights into the prediction accuracy of the model. An MSE of 0.0784 indicates that, on average, the model's predictions deviate from the actual values by a margin of approximately 0.28. While no model is infallible, such a low MSE in a domain rife with uncertainties underscores the reliability of the model's predictions. In essence, these statistical values highlight the robustness of our model in deciphering the intricacies of the gaming market. The substantial R2 index, coupled with a relatively low MSE, positions our model as a valuable tool for stakeholders looking to understand and predict trends within the gaming industry. This success can be attributed to the "top-label" approach's ability to filter out random influences, allowing the model to focus on the most influential and representative data points, leading to improved accuracy and robustness in its predictions.
