One thing I’ve observed in many data science tutorials when it comes to modeling, is that once a certain performance threshold is achieved on test data, rarely is the model deployed/pushed to production—and it’s a common case in the industry more broadly.

This tutorial aims to take modeling a step further by building a REST API and deploying the model into production. In addition to the REST API, we’re building a simple web application that predicts whether a piece of text belongs to any of these classes: atheism, computer graphics, medical science, Christianity, or politics.

You must’ve heard about “Vin Rouge” by @Nikhilodeon12 by now. The newly-verified Snap Star Nikhil created this lens, sparking the viral “Silhouette” challenge on TikTok. That’s right, TikTok.

The platform filled with its own filters, special effects, and AR tools. How did a Snapchat Lens end up over there?

In my article on lessons from my first deep learning hackathon, I introduced heatmaps. I mentioned that they highlight the regions in an image that the CNN focuses on while trying to make a prediction, and that it would be interesting to learn how they’re generated. Well, I finally know how. Let’s first go back and see what they look like.

In this post, we’re going to investigate the field of image compression and it’s applications in real world. We’ll explore various machine and deep learning techniques for image compression and inspect their pros and cons, and their practical feasibility in real-world scenarios.

So let’s get started!

Image compression refer to reducing the dimensions, pixels, or color components of an image so as to reduce the cost of storing or performing operations on them. Some image compression techniques also identify the most significant components of an image and discard the rest, resulting in data compression as well.

Google Colab is a cloud-based service that allows the execution of Python code and includes the ability to use and install new libraries. Put simply, you can leverage Google Colab to create a Jupyter Notebook and execute Python code using either a CPU or a free GPU.

Recently, there has been a huge rise in the implementation of artificial intelligence solutions, with new deep learning architectures being built and deployed across various industries. This rise could be attributed to two important factors:

Deep learning works primarily because of the vast amount of input data on which the deep neural net is trained. Hence, having a good labeled training dataset marks the first step in developing a highly accurate AI solution.

There are over 5 billion mobile device users all over the world. Such users generate massive amounts of data—via cameras, microphones, and other sensors like accelerometers—which can, in turn, be used for building intelligent applications. Such data is then collected in data centers for training machine/deep learning models in order to build intelligent applications.

However, due to data privacy concerns and bandwidth limitations, common centralized learning techniques aren’t appropriate—users are much less likely to share data, and thus the data will be only available on the devices.

Performance is the most important parameter in a mobile application—if it’s slow and/or buggy, then on the whole, it’s likely to be rejected by users. Then there’s a competitive factor. The better your app performs, the better the chances are for your app in the market.

Personally, I’d spend a couple of extra dollars for significantly better performance. Someone wise once said time is money, so let’s cut to the chase and look at how developers can optimize performance on Android.

Object detection is a technology related to computer vision and image processing that deals with detecting and locating instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos.

In this post, we’ll briefly discuss feature descriptors, and specifically Histogram of Oriented Gradients (HOG). We’ll also provide an overview of deep learning approaches to about object detection, including Region-based Convolutional Neural Networks (RCNN) and YOLO(you only look once).
