yolo deep learning

that the accuracy rate of YOLO in detecting small targets is about 8~10% than R-CNN, and the accuracy rate is higher than r-cnn in the detection of large targets. The accuracy of Fast-r-cnn+yolo is the highest, and the accuracy rate is 2.3% higher than that of FAST-R-CNN.5.4 SummaryYolo is a convolutional neural network that supports end-to-end training and testing, and can detect and recognize multiple ta

Training 135 rounds, batch size is 64, momentum is 0.9, learning rate delay is 0.0005. Learning schedule for: first round, The learning rate increased slowly from 0.001 to 0.01 (because the model

Recently began to learn YOLO, blog form to record their own learning distance, about installation, background, etc. are not introduced, directly start reading source code: 1. First find the main function in the darknet.c file, see the explanation of the parameters, and if it is YOLO, perform the Run_yolo function: int main (int argc, char **argv) {//test_resize

per second (selective Search+fast r-cnn is 2~3s one). It is important to note that the latest version has combined the RPN network with the Fast R-CNN network-the proposal of RPN acquired directly to the ROI pooling layer, which is really the framework for using a CNN network for end-to-end target detection. Summary: Faster R-CNN has been separating the region proposal and CNN classifications together, using an end-to-end network for target detection, pre-acquisition of region proposal, and the

Around 1995, Bruno Olshause

exploited in most applications of machine learning that involve real numbers. Many artificial intelligence tasks can be solved by designing the right set of features to extract for that task, then pro Viding these features to a simple machine learning algorithm. For example,a useful feature for speaker identification from sound is the pitch. One solution to this problem are to use machine
