In this article, we’ll learn about how Android developers can effectively use the Room database to improve data storage processes—and specifically, inserting and fetching records. But before jumping in, let’s first take a look at what we’ve previously been using for data storage in Android.

Before Room, and for a long time, Android developers have relied on SQLite as a primary database. SQLite was mostly easy to use and had some distinct advantages—it allowed data storage in a structured manner, performed better than other databases, and was a lightweight option compared to other 3rd party databases.

Many deep learning frameworks have been released over the past few years. Among them, PyTorch from Facebook AI Research is very unique and has gained widespread adoption because of its elegance, flexibility, speed, and simplicity.

Most deep learning frameworks have either been too specific to application development without sufficient support for research, or too specific for research without sufficient support for application development.

Deep learning has seen a lot of progress in recent years. It’s hard to think of an industry that doesn’t use deep learning. The availability of large amounts of data along with increased computation resources have fueled this progress. There have been many well known and novel methods responsible for the growth of deep learning.

One of those is transfer learning, which is the method of using the representations/information learned by one trained model for another model that needs to be trained on different data and for a similar/different task. Transfer learning uses pre-trained models (i.e. models already trained on some larger benchmark datasets like ImageNet).

Text summarization is a well-known task in natural language processing. In general, summarization refers to presenting data in a concise form, focusing on parts that convey facts and information, while preserving the meaning. To understand this better, we can think of summarization as a process to find a subset of data that contains all the information.

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.
