Hyperparameter Tuning: The process of adjusting the parameters of a machine learning model to optimize its performance.

Ensemble Learning: A technique where multiple models are combined to make more accurate predictions.

Overfitting: When a machine learning model is too complex and fits too closely to the training data, leading to poor generalization on new data.

Underfitting: When a machine learning model is too simple and fails to capture the complexity of the data, leading to poor performance on both training and new data.

Bias: When a machine learning model systematically produces incorrect predictions due to a lack of diversity in the training data.

Variance: When a machine learning model produces inconsistent predictions due to small variations in the training data.

Regularization: A technique used to prevent overfitting by adding a penalty term to the loss function of a machine learning model.

Gradient Descent: An optimization algorithm used to minimize the loss function of a machine learning model.

Backpropagation: A technique used to compute the gradients of the loss function with respect to the weights of a neural network, in order to update them during training.

Dropout: A regularization technique where randomly selected neurons are ignored during training, to prevent overfitting.

Batch Normalization: A technique used to improve the training of neural networks by normalizing the input to each layer.

Activation Function: A function applied to the output of a neuron in a neural network, to introduce nonlinearity and allow the network to learn complex functions.
