Continuous Control: Deep Deterministic Policy Gradient

This project repository contains my work for the Udacity’s Deep Reinforcement Learning Nanodegree Project 2: Continuous Control.

Project’s goal

In this environment, a double-jointed arm can move to target locations. A reward of +0.1 is provided for each step that the agent’s hand is in the goal location. Thus, the goal of the agent is to maintain its position at the target location for as many time steps as possible.

In this Project, I am training an agent to maintain its position at the target location for as many time steps as possible.

About Deep Reinforcement Learning

Reinforcement learning refers to goal-oriented algorithms, which learn how to attain a complex objective (goal) or maximize along a particular dimension over many steps; for example, maximize the points won in a game over many moves. They can start from a blank slate, and under the right conditions they achieve superhuman performance. Like a child incentivized by spankings and candy, these algorithms are penalized when they make the wrong decisions and rewarded when they make the right ones – this is reinforcement.

In this project I have chosen to use a Policy Based method called DDPG (Deep Deterministics Policy Gradient)
