What is the difference between BIO, NIO and AIO?

BIO, NIO, and AIO are all I/O models in Java. Their main differences and simple demos are described below. BIO (Blocking I/O) BIO is Java’s earliest I/O model, also known as synchronous blocking I/O. In BIO, each I/O operation blocks the current thread and does not continue executing the next statement until the operation is […]

Target detection algorithm improvement series adds EIOU, SIOU, AlphaIOU, FocalEIOU, etc.

YOLOv8 adds EIoU, SIoU, AlphaIoU, FocalEIoU, Wise-IoU, etc. Box_iou in yolov8 uses CIoU by default, and the code also contains GIoU and DIoU. The file path is: ultralytics/yolo/utils/metrics.py, and the function name is: bbox_iou Original code def bbox_iou(box1, box2, x1y1x2y2=True, GIoU=False, DIoU=False, CIoU=False, eps=1e-7): # Returns the IoU of box1 to box2. box1 is 4, […]

python thread pool/AIO (asynchronous non-blocking) example of sending http request

Tested multi-threading, thread pool, aio and other modes respectively Threads are limited by CPU scheduling, and AIO is most efficient under large request volumes. See the code for details. There are detailed instructions in the comments. The main method is the program entry point. “”” Comparison of various ways to initiate http requests in python […]

A must-have for YOLOv5 to gain points! Improved loss functions EIoU, SIoU, AlphaIoU, FocalEIoU, Wise-IoU

Table of Contents 1. The role of improving the loss function Second, specific implementation 1. Improving the role of loss function The role of the YOLOv5 loss function is to measure the difference between the predicted box and the real box, and update the parameters of the model based on these differences. It helps the […]

Explain in simple terms: Asynchronous programming and coroutines in Python, combined with examples to analyze the efficient use of `asyncio` and `aiohttp`

1. Introduction In the field of software development in recent years, asynchronous programming has become a hot topic. It opens new doors for us, allowing us to handle I/O-intensive tasks more efficiently, such as network requests, file reading and writing, etc. As a versatile programming language, Python will certainly not miss this trend. Starting from […]

Fastapi framework–aioredis asynchronous cache article

In an application, the need for caching is an essential part. For caching, we usually mainly use reids. However, there are relatively few libraries for client-side asynchronous support: 1 redis asynchronous client support library: Probably the main support libraries for asynchronous clients are: aioredis asyncio_redis aredis (seems to feel good too! Friendly and easier to […]
