Data pre-processing is a necessary step before any neural network can successfully ingest and analyze that data. The methods used to do this pre-processing are critical to the network’s performance.
Traditional data pre-processing methods include mean subtraction, normalization, and whitening, which have been around a long time—well before batch normalization came into the picture, which is what we’ll focus on in this post. To start, let’s define these pre-processing methods.
In this post, we’ll have explore the fundamentals of ensemble learning. Specifically, we’ll discuss techniques like bagging, boosting, and stacking in detail and take a brief look at various foundational algorithms that adopt these techniques.
Without further ado, let’s get started!
This article presents techniques for improving classification accuracy by aggregating various classifiers in different ways. These techniques are known as the ensemble methods.
Revamp that old security camera you have in your backyard — the one that doesn’t even record images! Security systems too costly? Get working on build your own with Twilio and OpenCV !
One of the largest boons of technology has been how, with time, advanced camera and surveillance systems have become so widely accessible. Twilio today has democratized communications channels like voice, text, chat, video, and email by virtualizing the world’s comms infrastructure through APIs that are simple enough for any developer to use, yet robust enough to power the world’s most demanding applications.

Today, we’re going to be building a RESTFUL API that takes in an image and make predictions using a TensorFlow MobileNet pre-trained model.
TensorFlow.js has many pre-trained models that can be used in projects out of the box. This saves developers the task of training a model from scratch. Here we’re going to explore the MobileNet pre-trained architecture
Genetic Algorithms (GAs) are a subset of Evolutionary Algorithms, which use mechanisms inspired by nature such as mutation, evolution, reproduction, etc. In spite of using advanced math, these algorithms work on principles which are derived from nature. Growth of an organism in its environment and its interaction with other beings in that environment can be modeled with simple mathematical expressions.

Machine learning tech is being integrated into mobile applications more and more today. Its integration helps optimize overall performance and can add significant functionality to an app’s experience. And over time, ML models can learn and improve from user interactions, making these experiences super intuitive and intelligent.
Here, we’re going to continue working with this technology in the Flutter ecosystem. Check out my previous post on ML in Flutter for more:

Camera effects have become a very normal part of daily social media or really any camera experience on the internet nowadays. With the whole pandemic situation, video calls have become way more popular, and to add a bit of artistic fun to the plain camera outputs, a lot of apps have integrated AR filters that overlay the face or change your background to hide that messy room.

Some things never change and a loading screen is one of them. If you own a smartphone, there is a chance you might come across 100s of them in a single day of usage. In fact, you may have seen one just before opening this story.

What is a behavior script? While initially this term looks complicated, it’s actually a surprisingly simple Lens Studio feature that allows you to turn your static projects into dynamic, interactive experiences.
You can find them in pretty much any Lens; from the most complex 3D experience, to a simple blush face paint Lens; Behavior scripts serve many functions and cover a wide range of commands in Lens Studio.
