We collect a large set of data using The Open Racing Car Simulator (TORCS) and classify the image features into three categories (sky-related, roadside-related, and road-related features).We then design two experimental frameworks to investigate the importance of each single feature for training a CNN controller.The first framework uses the training data with all three features included to train a controller, which is then tested with data that has one feature removed to evaluate the feature's effects. update process for Actor-Critic off-policy DPG: DDPG algorithm mainly follow the DPG algorithm except the function approximation for both actor. Note the Boolean sign must be in upper-case. The most common approaches that are used to address this problem are based on optimal control methods, which make assumptions about the model of the environment and the system dynamics. 1 INTRODUCTION Deep reinforcement learning (DRL) [13] has seen some success IEEE Sig. ECML 2005. The main benefit of this However, these success is not easy to be copied to autonomous driving because the state spaces in real world are extreme complex and action spaces are continuous and fine control is required. In particular, we select appropriate sensor information from TORCS as our, inputs and define our action spaces in continuous domain. Reinforcement learning as a machine learning paradigm has become well known for its successful applications in robotics, gaming (AlphaGo is one of the best-known examples), and self-driving cars. our model did not learn how to avoid collision with competitors. We adapted a popular model-free deep reinforcement learning algorithm (deep deterministic policy gradients, DDPG) to solve the lane following task. We start by implementing the approach of DDPG, and then experimenting with various possible alterations to improve performance. Springer, Cham (2016). : Onactor-critic algorithms. After training, we found our model do learned to release, the accelerator to slow down before the corner to av. How to control vehicle speed is a core problem in autonomous driving.

This is motivated by making a connection between the fixed points of the regularized policy gradient algorithm and the Q-values. ii. In recent years there have been many successes of using deep representations So we determine to use Deep Deterministic Policy Gradient (DDPG) algorithm, which uses a deterministic instead of stochastic action function. However, end-to-end methods can suffer from a lack of This translates to: In Deep Reinforcement Learning you do not train an intelligent agent with data, instead you teach it good behaviour by providing it with sensory information and objectives. The weights of these target networks are then updated in a fixed frequency. We de- Autonomous driving is a challenging domain that entails multiple aspects: a vehicle should be able to drive to its destination as fast as possible while avoiding collision, obeying trac rules and ensuring the comfort of passengers. The second framework is trained with the data that has one feature excluded, while all three features are included in the test data. In the modern era, the vehicles are focused to be automated to give human driver relaxed driving. Second, the Markov Decision Process model often used in robotics is problematic in our case because of unpredictable behavior of other agents in this multi-agent scenario. Meanwhile, we select a set of appropriate sensor information from TORCS and design our own rewarder. the same value, this proves for many cases, the "stuck" happened at the same location in the map. easier. The driving scenario is a complicated challenge when it comes to incorporate Artificial Intelligence in automatic driving schemes. in such difficult scenarios to avoid hitting objects and keep safe. It reveals, ob.track is the vector of 19 range finder sensors: each sensor returns the distance between, the track edge and the car within a range of 200 meters. We then train deep convolutional networks to predict these road layout attributes given a single monocular RGB image. SIAM J. Instead Deep Reinforcement Learning is goal-driven. denotes the speed along the track, which should be encouraged. In order to achieve autonomous driving in th wild, Y. achieve virtual to real image translation and then learn the control policy on realistic images. Learning to drive using inverse reinforcement. Notice that the formula does not have importance sampling factor. |trackPos| measures the distance between the car and the track line. While this approach works well when these maps are completely up-to-date, safe autonomous vehicles must be able to corroborate the map's information via a real time sensor-based system. mode, the model is shaky at beginning, and bump into wall frequently (Figure 3b), and gradually, stabilize as training goes on. Since taking intelligent decisions in the traffic is also an issue for the automated vehicle so this aspect has been also under consideration in this paper. Autonomous driving is a multi-agent setting where the host vehicle must apply sophisticated negotiation skills with other road users when overtaking, giving way, merging, taking left and right turns and while pushing ahead in unstructured urban roadways. In this paper, we present the state of the art in deep reinforcement learning paradigm highlighting the current achievements for autonomous driving vehicles.

Abstract: Autonomous driving is concerned to be one of the key issues of the Internet of Things (IoT). : Mastering the game of go with deep neural networks and tree search. The experiment results show that (1) the road-related features are indispensable for training the controller, (2) the roadside-related features are useful to improve the generalizability of the controller to scenarios with complicated roadside information, and (3) the sky-related features have limited contribution to train an end-to-end autonomous vehicle controller. Even stationary environment is hard to understand, let alone the environment is changing as the, because the action spaces is continuous and different action can be executed at the same time. and acceleration can vary from 0 to 300km. In this paper, we proposed a novel framework of reinforcement learning with image semantic segmentation network to make the whole model adaptable to reality. We show that our trained agent often dri, beginning, and gradually drives better in the later phases.
