Count-Based Exploration with Neural Density Models
WebThe count-based exploration uses a static hashing to map continuous states into discrete state, and then count the number of times a given state has been visited. Then, the classic RL algorithms are trained with a bonus reward that takes into account the number of times we have visited the state. WebJan 1, 2014 · with y i as the count response, λ i as the predicted count or rate parameter, and t i the area or time in which counts enter the model. When λ i is understood as applying to individual counts without consideration of size or time, t i = 1. When t i > 1, it is commonly referred to as an exposure, and is modeled as an offset.. Estimation of the Poisson … WebMar 3, 2024 · Bellemare et al. (2016) introduced the notion of a pseudo-count, derived from a density model, to generalize count-based exploration to non-tabular reinforcement learning. This pseudo-count was used to generate an exploration bonus for a DQN agent and combined with a mixed Monte Carlo update was sufficient to achieve state of the art … fall themes for preschoolers
