The third step of JPG coding is quantization. For the 8 * 8 block data after DCT change, we need to quantify the 8 * 8 data. In JPEG, quantization is to divide the data V by a certain number Q to get round (V / Q) instead of the original data. Then, when JPG […]

Abstract:Knowledge distillation is a common method of model compression 1、 Introduction to knowledge distillation 1.1 concept introduction Knowledge distillation is a common method of model compression, which is different from pruning and quantization in model compression. Knowledge distillation is to build a small lightweight model and train the small model by using the supervision information […]

Experience of experiment effect verification When to add an audience, when to add a multi-scale, and how to set the learning rate? Data enhancement My personal experience is that after the verification stage, when you start to run the absorption study, you must pay attention to the rationality of the data, and do not blindly […]

stayPrevious articleIn this article, I will introduce how to improve the accuracy of the model and how to support video recognition. In the past articles, I basically only introduced the implementation principle and application examples of the model, without excessive pursuit of accuracy. This is to let readers get rid of the details, but in […]

JS processing background returns large numbers The background is like this. If the background returns more than 16 digits, the front-end will automatically convert the excess mantissa to 0 1188726131910512635 => 1188726131910512000 The basic data class number in JavaScript is a double precision floating-point number. The maximum security range it can represent is plus or […]
