The equation "model = architecture + parameters," is a simplified way of expressing the components of a machine learning model:

1. Model: The overall system that makes predictions or decisions based on input data. It could be a regression model, a classification model, or another type of model depending on the task.

2. Architecture: Refers to the structure or design of the model. It includes the choice of algorithms, layers (in the case of neural networks), and how the information flows through the model. For example, if you're using a neural network, the architecture would include the number and type of layers, the activation functions, etc.

3. Parameters: These are the internal variables that the model learns from the training data. In the context of neural networks, parameters include weights and biases. During the training process, the model adjusts these parameters to minimize the difference between its predictions and the actual outcomes in the training data.
