Living in a “big” city like Casablanca, you tend to forget how the air is polluted — and somehow get used to it.
But don’t get fooled—in addition to emissions from vehicles, the air breathed by citizens in most big cities is contaminated by significant atmospheric emissions from factories and other sources of pollution.

On-device machine learning is gaining more and more traction among developers around the world. It’s now considered the best way to bring machine-learning powered tools and applications to the masses. The reason behind this is the ever-increasing on-device computational power that can be harnessed by developers, as well as the increased data privacy that on-device machine learning offers.

There has been tremendous development and progress over the past few years in how some technologies have impacted and blended into our human lives.
Deep learning has been at the forefront of such technologies and has found applications in many industries — retail, health, automobiles, finance, and transportation to name a few.
Neural Network (NN) Pruning is a task of reducing the size of a Neural Network by removing some of its parameters/weights.
Pruning is often performed with the objective of reducing the memory, computational, and energy bandwidths required for training and deploying NN models which are notorious for their large model size, computational expense, and energy consumption.

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
