Automatic Feature Engineering by Deep Reinforcement Learning
2019
We present a framework calledLearning Automatic Feature Engineering Machine (LAFEM), which formalizes theFeature Engineering (FE) problem as an optimization problem over aHeterogeneous Transformation Graph (HTG). We propose a Deep Q-learning on HTG to support efficient learning of fine-grained and generalized FE policies that can transfer knowledge of engineering "good" features from a collection of datasets to other unseen datasets.
