Discuss trade-offs between these approaches for demand forecasting.
How to Approach This
- Understand the bias-variance trade-off. High training accuracy but low test accuracy signals overfitting.
- Choose evaluation metrics carefully based on the problem. Accuracy alone is often insufficient.
- Feature engineering is often more impactful than model selection.
- Know when to use tree-based models (tabular data) vs neural networks (unstructured data).
- Handle class imbalance with SMOTE, class weights, or appropriate loss functions.

Core Concept: Dropout vs Regularization
Dropout and regularization are techniques used to prevent overfitting in machine learning models, particularly in deep learning. Dropout is a stochastic regularization method that randomly sets a ...
How It Works: Mathematical Mechanism
In dropout, during each training iteration, a dropout rate (e.g., 0.2) is applied, randomly setting 20% of the neurons in a layer to zero. The forward pass for each neuron is represented as:
[ z = ...
