What is a Model Parameter?

Definition

Model Parameter refers to the components within a machine learning model that are learned from the training data. These parameters are adjusted during the training process to minimize the error between the predicted outputs and the actual data. Model parameters play a crucial role in determining the dynamics and outcomes of the learning process, and they vary depending on the complexity of the model. For example, in a linear regression model, the parameters are the coefficients that are multiplied by the input features to produce output predictions.
