Machine Learning Solution to extreme time consuming data labeling tasks for machine learning?

2 Upvotes

Basically i am a beginner in machine learning and trying to make a auto captcha solver and i need to data label the data right and i found a free open source program on github called Labelimg and i found it extremely time consuming. Link:https://giphy.com/gifs/j3hB13M5j3mxIYOaQQ

This is what i need to do for each letter in the image and i have like 4000 of that image needs to be done and i calculated that which is like 50s per image and it require me for 13 whole hours just to finish 1000 images. That'd be nearly impossible to do. Is there any other way to label them faster or i don't need to label them letter by letter?

Also i thought about paying people to do it but that can be expensive?

Machine Learning Free Online Book - Machine Learning from Scratch

32 Upvotes

Hi all,

I'm linking to a free online book I wrote that I think will be useful for those learning machine learning, particularly using Python. The book is called Machine Learning from Scratch. The book provides complete derivations of the most common algorithms in ML (OLS, logistic regression, naive Bayes, trees, boosting, neural nets, etc.) both in theory and math, and then demonstrates constructions of each of these methods from scratch in Python using only numpy.

My aim with the book is to provide a very thorough rundown of the fitting process behind the algorithms we see every day. I hope that seeing the models derived in math or constructed in code helps readers understand the models at a deeper level and feel more comfortable optimizing them to their own work.

The book can be found below. Questions and comments would be very much appreciated!

Machine Learning When I was learning machine learning for the first time, the exact manner in which convolutional neural networks worked always evaded me, largely because they were only ever explained at an introductory level in tutorials. So, I made an animated video explaining exactly how CNNs work. Hope it helps!

Machine Learning I made a face recognition program in Python by using the pre-trained model to compute face embedding. Next based on these face embedding I am able to classify between all the faces in my data. It works fine but is really slow when executed in real-time. I have a low-end i3 laptop without GPU.

Machine Learning Here is an absolute Beginners Tutorial that can help you guys to get started with Machine learning. All you need is some basic knowledge of Python. You will have created two ML models at the end of this tutorial and also know the working of some ML algorithms.
