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 … WebMaximization of L(θ) is equivalent to minimization of − L(θ). And using the average cost over all data points, our cost function for logistic regresion comes out to be, J(θ) = − 1 mL(θ) = − 1 m( m ∑ i = 1yilog(hθ(xi)) + (1 − yi)log(1 − hθ(xi))) Now we can also understand why the cost for single data point comes as follows:
