Example: Tuning the learning rate, batch size, and number of layers in a neural network to improve its accuracy on tax prediction tasks.

8. Cross-Validation: Cross-validation is a technique used to assess the performance of a machine learning model by splitting the data into multiple subsets or folds. The model is trained and evaluated on each fold to estimate its generalization performance.

Example: Using k-fold cross-validation to evaluate the performance of a tax prediction model on different subsets of tax return data.

9. Bias-Variance Tradeoff: The bias-variance tradeoff is a fundamental concept in machine learning that describes the balance between the bias of a model (its assumptions) and its variance (sensitivity to fluctuations in the training data). A model with high bias may underfit the data, while a model with high variance may overfit the data.

Example: Adjusting the complexity of a decision tree model to find the optimal balance between bias and variance for tax prediction tasks.

10. Ensemble Learning: Ensemble learning is a machine learning technique that combines multiple models to improve the overall performance and generalization of the system. It leverages the diversity of individual models to make more accurate predictions.
