In this post, we’re going to investigate the field of sign language recognition and its applications in the real world.
We are going to discuss the approaches adopted by a research paper on Indian Sign Language Recognition and try to understand the merits and demerits of these methods from a practical point of view.

Feature selection is an important task for any machine learning application. This is especially crucial when the data in question has many features. The optimal number of features also leads to improved model accuracy. Obtaining the most important features and the number of optimal features can be obtained via feature importance or feature ranking. In this piece, we’ll explore feature ranking.

After working on a couple of projects using handwritten text recognition, I’m in total awe of this technology: Send an image to a REST endpoint, wait for the machine learning magic to happen, and then receive a bunch of JSON data with your recognized text as the response /output—wow!
But I already “awed” a lot about this in a blog post a while back. For anyone who’s interested in it and doesn’t know how to get started — check this out:

Whether you are a beginner or a seasoned ML developer, you’ve probably heard about (and most likely implemented) the Naive Bayes classifier. These classifiers are very helpful when you have smaller datasets and lesser computational power.
You might be aware of the world-famous scikit-learn implementation commonly used in Python:
We’ll get our hands dirty with Gaussian Naïve Bayes, its math, and the Android implementation. We’ll use our algorithm on the Iris dataset.
Animations, if done correctly are always a delight to see. Especially when it comes to mobile apps—adding subtle animations here and there can help make your app stand out of the crowd and give it a more polished feel.
Google also gave animations the central stage when it unveiled its newest design language—Material Design—back in 2014!

If you’re familiar with natural language processing or starting to learn about it, you might have come across NLTK (Natural Language Tool Kit), Stanford Core NLP, etc.
Think of it this way. Natural language processing (in Python) is a kingdom, and NLTK is the king. Everyone admires the king and respects what he has done for the kingdom. But there comes a time when every king should step down and make way for the next generation

In this article, we’ll discuss how to increase these accuracy values, how to validate the model using a validation set, and examine overfitting and find a solution to this common machine learning problem.

This is the fifth blog post in my AutoML Vision Edge series. The post will help you run AutoML Edge models on Docker containers. If you haven’t been following this blog post series till now, here’s a quick recap:
We started the series by learning how we can train and run inference on an edge-ready ML model in hours using Google Cloud’s AutoML.

Though I support learning machine learning from scratch, I’m always interested in validating the classic Cost + Effort < Output.
Machine learning is interesting conceptually, but at the same time, it’s hard to understand for a beginner. A lot of effort is needed to master and understand the foundational mathematics and logic. But luckily, there are a number of tools available online to decrease these efforts exponentially. One of them is Google Cloud AutoML.
Synthesizing and editing video portraits—i.e., videos framed to show a person’s head and upper body—is an important problem in computer graphics, with applications in video editing and movie postproduction, visual effects, visual dubbing, virtual reality, and telepresence, among others.
The problem of synthesizing a photo-realistic video portrait of a target actor that mimics the actions of a source actor—and especially where the source and target actors can be different subjects—is still an open problem.
