Reinforcement Learning and Deep RL Python Theory and Projects - DNN Dropout

The video tutorial explains overfitting in machine learning, where a model learns the training data too well but fails to generalize to unseen data. It discusses how model complexity, defined by the number of parameters, contributes to overfitting. The tutorial introduces dropout as a technique to mitigate overfitting by randomly freezing neurons during training, effectively creating an ensemble of models. This approach reduces the model's effective parameters and enhances generalization. The video also highlights the connection between dropout and ensemble learning, and concludes with a brief mention of implementing dropout in PyTorch.

What are the implications of training on different models in each iteration of stochastic gradient descent?

Explain how dropout can be viewed as a form of ensemble learning.
