The advent of machine learning on mobile has opened doors for a bunch of new opportunities. While it has allowed ML experts to tap into the mobile space, the other end of that equation is actually the show-stealer. Letting mobile application developers dabble in machine learning has actually made its with mobile application development so exciting.

The best thing is, that you needn’t be a machine learning expert in order to train or run models. Core ML, Apple’s machine learning framework, provides an easy-to-use API that lets you run inference (model predictions), fine-tune models, or re-train on the device.

The sports world is an entertainment business at its core, and technology is starting to play a more important role in the expansion of this business. From the NHL to the NFL, MLB, NBA and NASCAR, virtually every major U.S. sports league is now incorporating AI to expand its bottom line.

The North American sports industry is expected to rake in $73.5 billion in revenue by 2019 in the form of gate revenues, merchandising, sponsorships, and media rights.

XGBoost…why we talk about it so much

Because it’s really GOOD.

Indeed, XGBoost, a gradient boosting algorithm, has been consistently employed in the winning solutions in Kaggle competitions involving structured data. XGBoost has excellent precision and adapts well to all types of data and problems, making it the ideal algorithm when performance and speed take precedence.

From training to experimenting with different parameters, the process of designing neural networks is labor-intensive, challenging, and often cumbersome. But imagine if it was possible to automate this process. That imaginative leap-turned-reality forms the basis of this guide.

We’ll explore a range of research papers that have sought to solve the challenging task of automating neural network design.

In this guide, we assume that the reader has been involved in the process of designing neural networks from scratch using one of the frameworks such as Keras or TensorFlow.

Depression is among the most prominent mental illnesses, affecting more than 300 million people globally, according to the World Health Organization (WHO).

Beyond the potentially devastating personal and social effects of depression, the economic costs related to this mental health issue have substantially increased in recent years. In fact, it’s currently estimated to cost the global economy over $1 trillion USD each year.

Since we founded Fritz AI in late 2017, we’ve seen tremendous growth in the Boston-area tech scene. What was once a city whose tech economy centered on academia, biotech, and robotics, Boston has flourished into one of the most attractive locations for all kinds of tech start-ups, early- and late-stage alike.

Image Classification and Convolutional Neural Networks

Over the past few years, deep learning techniques have dominated computer vision. One of the computer vision application areas where deep learning excels is image classification with Convolutional Neural Networks (CNNs).

Transfer learning, an approach where a model developed for a task is reused as the starting point for a model on a second task, is an important approach in machine learning. Prior knowledge from one domain and task is leveraged into a different domain and task.

Transfer learning, therefore, draws inspiration from human beings, who are capable of transferring and leveraging knowledge from what they have learned in the past for tackling a wide variety of tasks.
