Machine Learning Concepts

Validation Set: Used to tune model parameters and evaluate performance during training without biasing the test set results.
Reinforcement Learning: A type of machine learning where agents learn to make decisions by interacting with an environment and optimizing rewards.
Challenges in Deep Neural Networks: Common issues include vanishing and exploding gradients, which affect the training and stability of models.
Activation Functions: ReLU (Rectified Linear Unit) is a widely used activation function in neural networks that introduces non-linearity and helps mitigate issues related to vanishing gradients.
Layer Types in Neural Networks: Typical layer functions include activation, architecture definition, and weight initialization. However, quantifying the difference between predicted and actual values is not a layer type.
Backpropagation: Refers to the method of adjusting weights in a neural network based on the calculated error, essential for minimizing loss during training.
Clustering: An application of machine learning that groups similar items based on characteristics or patterns.
Preventing Overfitting: Techniques such as regularization, dropout, and early stopping can be applied to neural networks to avoid overfitting to training data.
Sigmoid Activation Function: Outputs a value between 0 and 1, commonly used in binary classification tasks.
Difference between Regression and Classification: Regression predicts continuous outcomes, while classification predicts discrete class labels.
