Further, we show that this approach can be combined with existing model-free algorithms to yield a state-of-the-art planner in sparse-reward, long-horizon tasks. 1 Introduction The standard treatment of reinforcement learning relies on decomposing a long-horizon problem into smaller, more local ...

Hands-On Machine Learning with Scikit-Learn and TensorFlow

In 2006, Geoffrey Hinton et al. published a paper1 showing how to train a deep neural network capable of recognizing handwritten digits with state-of-the-art precision (>98%). They branded this technique “Deep Learning.” Training a deep neural net was widely considered impossible at the time,2 and most researchers had abandoned
