Reinforcement Learning-Driven Adaptive Model Selection and Blending for Supervised Learning

Towards AI

Traditionally, we rely on cross-validation to test multiple models XGBoost, LGBM, Random Forest, etc. and pick the best one based on validation performance. Inspired by its reinforcement learning (RL)-based optimization, I wondered: can we apply a similar RL-driven strategy to supervised learning?

This Only Applies to Supervised Learning Introduction If you’re like me then you probably like a more intuitive way of doing things. When it comes to machine learning, we often have that one (or two or three) “go-to” model(s) that we tend to rely on for most problems. Call-To-Action Enjoyed this blog post?

Training error and generalization error In supervised learning, we assume that training data and test data follow the IID assumption: data is drawn independently from identical distributions. Cross Validation Incorporating a validation set in addition to a test and train set helps us address the above problem and select a better model.
