Estimation of Gradients and Coordinate Covariation in Classification

NettetThese are actually coordinates with respect to the standard basis. If you imagine, let's see, the standard basis in R2 looks like this. We could have e1, which is 1, 0, and we have e2, which is 0, 1. This is just the convention for the standard basis in R2. And so we could say s is equal to the set of e1 and e2. NettetWe introduce an algorithm that learns gradients from samples in the supervised learning framework. An error analysis is given for the convergence of the gradient estimated by the algorithm to the true gradient. scroller blood
