From Kaggle to classrooms, one of the first lessons in machine learning involves decision trees. The reason for the focus on decision trees is that they aren’t very mathematics heavy compared to other ML approaches, and at the same time, they provide reasonable accuracy on classification problems.

In this post, we’ll learn to use basic React Native animations while creating a RN project that has an animated search bar. To do this, we’ll use the react-native-animatable package.

In most applications, animations are repetitive swipes, slides, bounces, and so on; react-native-animatable provides preconfigured animated components that you can use without rewriting commonly-used animations yourself. The package provides a standard set of easy-to-use animations and declarative transitions for React Native.

Natural Language Processing (NLP) helps computers (machines) “read and understand” text or speech by simulating human language abilities.

However, in recent years, NLP has grown rapidly because of an abundance of data. Given that more and more unstructured data is available, NLP has gained immense popularity.

The purpose of this article series NLP Chronicles is to introduce you to the NLP field while offering practical knowledge on how to tackle various NLP-related tasks. There is no final destination of this series. It’s best to think of this as wandering into the wilderness of NLP.

Lenses aren’t just for making your selfies better — they can also be used as an effective tool for marketing and promotion. This has been primarily noticed by musicians, who are making use of this immersive medium to bring their songs digital and worldwide.

You may be wondering, are the musicians themselves making these Lenses? It may come as a surprise to know that many Official Lens Creators are actually the masterminds behind these AR experiences, merging the Lens market with big names like Megan Thee Stallion, Green Day, and Dua Lipa — an artist from any genre can have a Lens (The Bee Gees even have one!)

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.
