Yolo series is a very classic structure in the field of target detection. Although there are many higher quality and more complex networks, the structure of Yolo can still bring a lot of inspiration to Algorithm Engineers. These three papers look like a parameter adjustment manual. They teach you how to use various tricks to […]

This article will introduce convolutional neural network (CNN). CNN model is very suitable for image-related learning, such as image classification and captcha recognition, and can also cooperate with other models to realize OCR. Using Python to process images Before we go into CNN, let’s take a look at how to use Python to process images. […]

Usage scenarios: In the multi-dimensional summary of data, it is necessary to merge the data of different data types and different data precision into a table, and the accuracy of relevant calculation will be lost. Troubleshooting: After segmented investigation, the cause of the loss was found, and the sum function caused the precision loss […]

Since the emergence of Bert, great progress has been made in NLP field. With the increase of model capacity, the progress of Bert model has been improved in each dataset. However, although the size of the upgrade model can improve the effect of downstream tasks to a certain extent, if the scale of the model […]

Default time type in MySQL（datetimeandtimestamp）If the precision of the time value set in is less than seconds, it will be rounded off, which may cause the value in the database to be one more second than the original value. In other words, the records that belong to today may be recorded to tomorrow. Here is […]

Environment: Django 1.9.7 Background When Django migrate generates the table structure, it adds 6-bit precision to the datetimefield type processing. There is no problem with only Django processing, but how to read this field by other frameworks will not read the field value. Reference link The DATE, DATETIME, and TIMESTAMP Types Support microsecond precision in […]

As a contemporaneous paper of nasnet, blockqnn also shifts its focus from the overall network to block wise. The overall idea is probably the block version of metaqnn with some minor modifications added. With early stop strategy, the computing resources are very small, but the performance is worse than that of nasnet in the same […]
