Learning Deep Features for Discriminative Localization
cnnlocalization.csail.mit.eduweights of the output layer on to the convolutional feature maps, a technique we call class activation mapping. As illustrated in Fig. 2, global average pooling outputs the spatial average of the feature map of each unit at the last convolutional layer. A weighted sum of these values is used to generate the final output. Similarly, we compute a

Parametric Rectifiers We show that replacing the parameter-free ReLU by a learned activation unit improves classification accuracy2. Definition. Formally, we define an activation function: f(yi)= yi, if yi > 0 aiyi, if yi ≤ 0. (1) Here yi is the input of the nonlinear activation f on ...

Our SuperPoint architecture is inspired by recent ad-vances in applying deep learning to interest point detection and descriptor learning. At the ability to match image sub-
Siamese Neural Networks for One-shot Image Recognition

Thus a cross-entropy objective is a natural choice for train-ing the network. Note that in LeCun et al., they directly learned the similarity metric, which was implictly defined by the energy loss, whereas we fix the metric as ...

arxiv.orgcoder consists of convolutional layers, spatial downsam-pling via pooling and non-linear activation functions. Our encoder uses three max-pooling layers, letting us define H c = H=8 and W c = W=8 for an image sized H W. We refer to the pixels in the lower dimensional output as “cells,” where three 2 2 non-overlapping max pooling op-
