    • Use techniques like cross-validation to assess model performance.
    • Regularization methods (like L1 and L2) can help prevent overfitting by penalizing overly complex models.
    • Adjust model complexity based on the size and nature of the dataset, utilizing machine learning optimization techniques.

    8.4. Bias-Variance Tradeoff

    The bias-variance tradeoff is a fundamental concept in machine learning that describes the balance between two types of errors that affect model performance.

    • Bias refers to the error due to overly simplistic assumptions in the learning algorithm. High bias can lead to:  
      • Underfitting, where the model fails to capture the underlying trends in the data.
      • A model that is too rigid, resulting in poor predictions.
    • Variance refers to the error due to excessive sensitivity to fluctuations in the training data. High variance can lead to:  
      • Overfitting, where the model captures noise along with the underlying patterns.
      • A model that performs well on training data but poorly on new, unseen data.

    To achieve a good model:

    • Aim for a balance where both bias and variance are minimized.
    • Use techniques such as:  
      • Ensemble methods (like bagging and boosting) to reduce variance.
      • Cross-validation to ensure that the model generalizes well to unseen data.
      • Regularization can also help in managing the tradeoff by controlling model complexity.

    9. Optimization Techniques

    Optimization techniques are crucial in training machine learning models, as they help minimize the loss function and improve model performance.

    • Gradient Descent is the most common optimization algorithm, which works by:  
      • Iteratively adjusting model parameters in the direction of the steepest descent of the loss function.
