Supervised learning in PyTorch involves training a model on a labeled dataset. The process involves defining a model architecture, selecting a loss function and optimizer, splitting the dataset into training and validation sets, and finally training the model using the training data. During training, the model uses backpropagation to update its parameters and minimize the loss function. The validation set is used to evaluate the model's performance and prevent overfitting.

8. Build projects: Building projects is the best way to learn deep learning. Start with simple projects and gradually move on to more complex ones.
Remember, deep learning is a vast field, and it takes time and effort to master it. Keep practicing, and you will get there.
supervised learning
Supervised learning is a type of machine learning where the algorithm is trained on a labeled dataset, meaning that the input data is paired with the correct output or target variable. The goal of supervised learning is to learn a mapping between the input and output variables so that the algorithm can make accurate predictions on new, unseen data.
Supervised learning algorithms can be used for a variety of tasks, such as classification, where the output variable is a categorical label, or regression, where the output variable is a continuous value.
Examples of supervised learning include predicting the price of a house based on its features (regression), classifying emails as spam or not (classification), or recognizing handwritten digits (classification).
