In the current version (known as “Faster R-CNN”), a “sliding window” based technique (described in the previous section) is used to generate a set of dense candidate regions and then a neural network driven region proposal network is used to rank region proposals according to the probabi...
Fig. 4: Inception-v1 architecture. This CNN has two auxiliary networks (which are discarded at inference time). Architecture is based on Figure 3 in the paper. This 22-layer architecture with 5M parameters is called the Inception-v1. Here, the Network In Network (see Appendix) approach is...
ConvNets are used primarily to look for patterns in an image. You did that by convoluting over an image and looking for patterns. In the first few layers of CNNs the network can identify lines and corners, but we can then pass these patterns down through our neural net and start recogni...
AlexNet’s architecture was extremely similar to LeNet’s. It was the first convolutional network to employ the graphics processing unit (GPU) to improve performance. Convolutional filters and a non-linear activation function termed ReLU are used in each convolutional layer (Rectified Linear Unit). ...
Overall architecture 这部分讲了AlexNet的整体结构,如前图所示。全连接的最后一层是softmax层,共有1000个输出。计算的过程分成两部分是因为这两部分是在两块GTX580上计算的。 ReLU在每个卷积层和全连接层后。LRN层在第一个和第二个卷积层之后。Max-pooling层在两个LRN层与第四个卷积层之后。
Figure 8. Model Architecture.We use the binary cross entropy loss which is given by the formula below:Here x1 and x2 are the consumer and shop image features respectively and t is the target which is 1 for similar pairs and 0 for dissimilar pairs. Using t...
Schematic diagram of the FCN architecture as proposed by Long et al. (2015). Predictions (also referred to as ’scores’) within the network are forwarded to deeper layers to relate respective activations to the original spatial resolution. ...

This feature increases the number of L network connections, for a traditional L CNN layers with a connection between each layer, to [L(L-1)]/2 Credits: original paper Although the DenseNet architecture has a similar approach to the ResNet architecture, with the addition of short ...
