Python Advanced- GroupBy uses

Another post starts with you beautiful people!
Today we will learn about how to use GroupBy in datasets.
For more details please visit here what is groupby?

We will apply groupby in the drinks data set which you can download from here- download drinks dataset

Let's starts some hand on the drinks dataset-

The result will look like below -

Now let's find out some info from this dataset-

Try out above examples in your notebook and you will come to know in which situation we can use groupby,mean,median.
Comment if you face any issue.

YOLObile- a new state of the art Real-Time Object Detection model for Mobile Devices

Another post starts with you beautiful people! Thanks for giving so many views on my previous post 👍. I am glad to see my previous posts are helping people to use state of the art object detection and recognition deep learning model in their projects. If you are new to my blog, I recommend seeing once my previous posts, and you will not be disappointed if your goal is to learn applied computer vision free of cost. Continuing my journey of sharing knowledge in this post I am going to share with you a new state of the art framework for object detection on mobile devices- YOLObile 📱 There has been a trade-off between speed and the accuracy of object detections. For example, the state of the art, YOLOv4 model gives us a very accurate detection but its speed is slow if we want to use it on a mobile device. On the other hand, its lighter version YOLOv4-tiny works very fast on a mobile device but its accuracy reduces. For a detailed comparison of FPS vs mAP you can ...

How to CORRECTLY convert Darknet/Yolov4 weights to TFLite format?

Greetings, computer vision practitioners👮! I hope you're all doing well in your projects. Recently, I received a new requirement from a client regarding an object detection solution that had been successfully deployed as a REST API. The solution was seamlessly integrated into both web and mobile applications. However, the client encountered network reliability issues, particularly in rural areas where poor connectivity occasionally caused the solution to fail on mobile devices💔. As we know, network disruptions are a common challenge, but they become critical when they impact business operations. My client sought a robust solution to address this issue, ensuring uninterrupted functionality regardless of network conditions. In this blog post, we will explore how I tackled this challenge and implemented an effective solution💓. The Solution: Enabling Offline Object Detection for Mobile Devices Given that network connectivity issues are beyond our control, the most effective soluti...

How to use opencv-python with Darknet's YOLOv4?

Another post starts with you beautiful people 😊 Thank you all for messaging me your doubts about Darknet's YOLOv4. I am very happy to see in a very short amount of time my lovely aspiring data scientists have learned a state of the art object detection and recognition technique. If you are new to my blog and to computer vision then please check my following blog posts one by one- Setup Darknet's YOLOv4 Train custom dataset with YOLOv4 Create production-ready API of YOLOv4 model Create a web app for your YOLOv4 model Since now we have learned to use YOLOv4 built on Darknet's framework. In this post, I am going to share with you how can you use your trained YOLOv4 model with another awesome computer vision and machine learning software library- OpenCV and of course with Python 🐍. Yes, the Python wrapper of OpenCV library has just released it's latest version with support of YOLOv4 which you can install in your system using below command- pip install opencv-pyt...
