In this tutorial, we’re going to talk about a type of unsupervised learning model known as Boltzmann machines. We assume the reader is well-versed in machine learning and deep learning. We’ll use PyTorch to build a simple model using restricted Boltzmann machines. This model will predict whether or not a user will like a movie.

A Boltzmann machine defines a probability distribution over binary-valued patterns. What makes Boltzmann machine models different from other deep learning models is that they’re undirected and don’t have an output layer. The other key difference is that all the hidden and visible nodes are all connected with each other. Due to this interconnection, Boltzmann machines can generate data on their own. As such, it can be classified as a generative deep learning model.

But there was one major issue with Prisma. It had to be run through JVM and had memory issues. The Prisma Framework is rewritten in Rust, and it addresses the issues from Prisma 1.

Prisma 1 also required a server in front of your backend server, while with the Prisma Framework, the query engine is now a bundled executable that’s run alongside the backend on the same server.

In my previous article, we had a detailed discussion on the one-shot learning problem and how various algorithms tackled it in order to determine which approach was the most effective, and we settled on siamese networks. I’d encourage you to check it out:

But is this enough?Not quite! We need some hands-on-experience to actually learn how implement it. And what could be more relatable these days than facial recognition, which just happens to be a perfect use case for one-shot learning?

This post is a part of a series about feature engineering techniques for machine learning with python.

You can check out the rest of the articles below — links will be added as posts go live:

Welcome back! Part two in our series intends to give you an overview of the type variable, which you can find in a given dataset. It’s essential to know the different variables’ types to better to engineer them.

This article is a part of a series about feature selection techniques. You can check out the rest of the articles as they are/become available:

Welcome back! This post will give you an overview of wrapper methods for feature selection.

In the last post in the series, we explored the filter methods that tend to select features independently and work with (essentially) any machine learning algorithm. Consequently, one of the disadvantages of these methods is that they tend to ignore the effect of the selected feature subset on the performance of the algorithm.

Waymo has driven more than 20 million miles on public roads in over 25 cities. They also drove tens of billions of miles in simulations (as we’ll see later in the article). Additionally, Waymo is operating a taxi service in the United States, transporting passengers—for real—without a driver.

Given their growing presence in the real world, I want to dive deep into Waymo’s technology so you can understand what’s actually behind this giant.

In this tutorial, we’ll continue learning the various use-cases of the TensorFlow.js library. Our previous tutorial used this library for real-time human pose estimation. Here, we’re going to detect hand gestures using the library.

In this tutorial, we’re going to focus our pose algorithm on a smaller area—human hands. We are going to detect the hand poses and gestures using the TensorFlow.js library. Like in the previous tutorial, we are going to make use of a webcam for gesture detection and canvas for drawing or displaying the result of the detection.

Machine learning is a buzzword nowadays. There are plenty of theories going around, but it’s hard to see real applications that can be built by an indie developer.

Developing an end-to-end machine learning system requires a wide range of expertise in areas like linear algebra, vector calculus, statistics, and optimization.

Therefore, from a developer’s perspective, there’s a high learning curve that stands in the way, but the latest tools take care of most of the work for developers, leaving them free to code.

The power of React Native as a framework continues to increase over time. For those who are unfamiliar, React Native is a cross-platform framework developed by Facebook. It’s open source and lets you build mobile applications using JavaScript as its core.

Thanks to Nicolas Gallagher’s open source project React Native for Web, now you can use React Native API components to build a web application that uses React DOM as its core. React Native already makes it convenient to write mobile apps for two platforms: iOS and Android. And now the web is slowly entering the picture. 🤩
