YOLOv4- Speed & Accuracy

Last few years object detection has starts maturing in ever since R-CNN was released, the competition remains cut-throat. YOLOv4 has again claim to have state-of-the-art(SOTA) accuracy while maintains a high processing frame rate. It achieves an accuracy of 43.5% AP (65.7% AP₅₀) for the MS COCO with an approximately 65 FPS inference speed on Tesla V100 as per the graph below. In object detection, higher accuracy & precision is few of many things we definitely want . We want the model to run smoothly in the edge devices like Rasberry Pi, Jetson Nano, Intel boards. How to process streaming real time video with these low power and low cost hardware becomes important and challenging pushing the need to get for robotics ,business and much more.(Code is Shared in the end with Video walk-through)

YOLOv4 is twice as fast as EfficientDet with comparable performance.

The YOLO v4 release lists three authors: Alexey Bochkovskiy, the Russian developer who built the YOLO Windows version, Chien-Yao Wang, and Hong-Yuan Mark Liao.(Unfortunately, the Creator of YOLO Joseph Redmon announced he was not pursuing computer vision due negative impact of his work )

As per the authors

Compared with the previous YOLOv3, YOLOv4 has the following advantages:

It is an efficient and powerful object detection model that enables anyone with a 1080 Ti or 2080 Ti GPU to train a super fast and accurate object detector.

The influence of state-of-the-art “Bag-of-Freebies” and “Bag-of-Specials” object detection methods during detector training has been verified.

The modified state-of-the-art methods, including CBN (Cross-iteration batch normalization), PAN (Path aggregation network), etc., are now more efficient and suitable for single GPU training.

How to Speed Up Your Day-To-Day Work in Python

Use all the computing power available to you

In my day-to-day data work, I routinely find myself running a lot of for loops. These can take minutes to complete, which isn’t necessarily a long time, but looping is embarrassingly parallelizable. We can do better.

In this article, I will discuss how to make more efficient use of your time when working in Python. Whether you work on a laptop or a high-performance computer (HPC), you can speed up your workflow by taking full advantage of all the computing power available to you. This can be achieved with the Dask and Dask-jobqueue libraries. This post will discuss how to create and use a dask cluster on your local computer and an HPC.

Dask is a Python library for parallel computing and dask-jobqueue lets you interact with job schedulers, such as Slurm, from a Jupyter Notebook. Dask makes simple things are easier and complex things are possible and itsnumpy and pandas-like API makes writing code familiar to Pythonic data practitioners.
