Data Structures tutorial, covering all the basic and advanced topics of Data Structures with great concepts and shortest lessons. The function torch. In addition, below you’ll find a few links to tutorials and tools for classification and representation learning tasks. After all proposals get reshaped to a fix size, send to a fully connected layer to continue the classification How it works Basically the RPN slides a small window (3x3) on the feature map, that classify what is under the window as object or not object, and also gives some bounding box location. Visualize the training result and make a prediction.
