In contrast, neural network models utilize interconnected layers of artificial neurons to capture complex patterns and nonlinear relationships within the data.

Linear Regression Model

The linear regression model serves as an example of an explanatory model, employing statistical analysis and model assumptions to perform inferential statistics that aid in understanding the relationships between variables and making predictions based on these relationships.

This model is widely used in various fields such as economics, finance, and social sciences to analyze the impact of independent variables on a dependent variable. It assumes a linear relationship between the variables and relies on the least squares method to estimate the parameters. It is crucial to assess the model’s assumptions, including linearity, independence, homoscedasticity, and normality of residuals, to ensure the validity of the statistical inferences drawn from the model. By understanding these aspects, researchers can effectively interpret the results and draw meaningful conclusions from their analyses.

Decision Tree Model

The decision tree model represents an explanatory model that prioritizes interpretability and model simplicity, providing clear and concise model explanations that aid in understanding complex decision-making processes based on the input features.

This model is constructed as a tree structure, where each internal node represents a decision based on a specific feature, and each leaf node represents the outcome or decision. The simplicity of the decision tree makes it easy to understand and interpret, even for individuals without extensive technical knowledge. The transparency of the decision-making process allows stakeholders to grasp the reasoning behind the model’s predictions, enhancing trust and acceptance. The decision tree’s capacity to handle both numerical and categorical data further adds to its versatility and practical application in various domains.
