WebJul 17, 2024 · A Machine Learning model devoid of the Cost function is futile. Cost Function helps to analyze how well a Machine Learning model performs. A Cost function basically compares the predicted values with the actual values. Appropriate choice of the Cost function contributes to the credibility and reliability of the model. Loss function vs. … WebWe present a novel method for reliable robot navigation in uneven outdoor terrains. Our approach employs a novel fully-trained Deep Reinforcement Learning (DRL) network that uses elevation maps of the environment, robot pose, and goal as inputs to compute an attention mask of the environment. The attention mask is used to identify reduced …
