Here are some key concepts in machine learning Course in Pune:

Algorithms: Sets of rules or instructions for solving problems. Common algorithms include decision trees, support vector machines, and neural networks.

Training Data: The dataset used to train models, containing input features and corresponding labels (in supervised learning).

Features: Individual measurable properties or characteristics of the data. Selecting relevant features is crucial for effective modeling.

Labels: The output variable in supervised learning. Labels indicate the expected outcome for given input features.

Overfitting and Underfitting: Overfitting occurs when a model learns noise from the training data too well, while underfitting happens when it fails to capture the underlying trend.

Validation and Testing: Processes to evaluate model performance. Validation helps tune parameters, while testing assesses how well the model generalizes to new data.

Cross-Validation: A technique to ensure that the model performs well across different subsets of data, improving its reliability.

Hyperparameters: Settings that govern the training process (e.g., learning rate, number of layers in a neural network). Tuning them can significantly impact model performance.

Gradient Descent: An optimization algorithm used to minimize the loss function by iteratively adjusting model parameters.

Ensemble Learning: Combines multiple models to improve accuracy and robustness, with methods like bagging and boosting.
