Variables

In data science and artificial intelligence, a variable is a named memory location that stores a value. Variables are used to store data that can be manipulated and analyzed. In programming, variables can be assigned different data types such as integers, floats, strings, and booleans. In machine learning, variables are used to represent features and labels in a dataset. The values of these variables can be modified during the training process to optimize the model's performance. Variables can also be used to store the parameters of a model, such as weights and biases, which are updated during the training process to improve the model's accuracy.
