Jaccard Index (IoU, degree of overlap)    Jaccard Index (Jaccard coefficient), or Jaccard Overlap (Jaccard Overlap) or intersection over Union (IoU), measures the degree of overlap between the two frames. This index can reflect the proximity between the prediction frame and the real frame, which will be used in calculating loss and N ...

It is very difficult to train deep neural networks, especially in short practice. In this section, we will introduce batch normalization, which is a popular and effective technology to continuously accelerate the convergence speed of deep networks. After the combination, the residual will be introduced quickly, and batch normalization enables r ...

preface The image with low resolution caused by enlargement and reduction is converted into an image with high resolution. More attention is paid to filling new pixels in the process of reconstructing the picture. SRCNN is also the ancestor of applying deep learning to image reconstruction. The network structure is very simple, so I deci ...

1.3.4. Target file system 1.3.4.1. Firmware OpenCL firmware includes pre encapsulated DSP TIDL Library (with hard coded core) and EVE TIDL library following custom accelerator model. OpenCL firmware is downloaded to DSP and M4/EVE immediately after Linux boot: - dra7-ipu1-fw.xem4 -> /lib/firmware/dra7-ipu1-fw.xem4.opencl-monitor - dra7-dsp1 ...

PyTorch Foundation In this book, we widely use PyTorch to implement our deep learning model. PyTorch is an open source, community driven deep learning framework. Unlike Theano, Caffe and TensorFlow, PyTorch implements a "tape based automatic differentiation" method that allows us to dynamically define and execute computational gr ...

During this period, I participated in the Coggle 30 days of ML punch in and signed up for the CV competition. The competition Title address is: https://challenge.xfyun.cn/topic/info?type=key -points-of-human-face&ch=dw-sq-1 Overview of competition questions: Face recognition is a biometric recognition technology based on human facial f ...

Improvement of YOLOv5 - loss function for target detection flyfish Full code download address The improved source code is fully compatible with the original YOLOv5:v5 version. At the same time, the backbone supports mobilenetv3 and shufflenetv2, and the original backbone supports all of them Categories include relationships. For example, a t ...
