Where the training of machine learning models is concerned, there's always a risk of overfitting -- or corresponding to closely -- to a particular set of data. In point of fact, it's not infeasible that popular machine learning benchmarks like the Arcade Learning Environment encourage overfitting, in that they have a low emphasis on generalization. That's why OpenAI -- the San Francisco-based research firm cofounded by CTO Greg Brockman, chief scientist Ilya Sutskever, and others -- today released the Procgen Benchmark, a set of 16 procedurally-generated environments (CoinRun, StarPilot, CaveFlyer, Dodgeball, FruitBot, Chaser, Miner, Jumper, Leaper, Maze, BigFish, Heist, Climber, Plunder, Ninja, and BossFight) that measure how quickly a model learns generalizable skills. It builds atop the startup's CoinRun toolset, which used procedural generation to construct sets of training and test levels. "We want the best of both worlds: a benchmark comprised of many diverse environments, each of which fundamentally requires generalization," wrote OpenAI in a blog post.

Two of the most popular machine learning models used today are BERT, for natural language processing (NLP), and Mask R-CNN, for image recognition. Over the past several months, AWS has significantly improved the underlying infrastructure, network, machine learning (ML) framework, and model code to achieve the best training time for these two popular state-of-the-art models. Today, we are excited to share the world's fastest model training times to date on the cloud on TensorFlow, MXNet, and PyTorch. You can now use these hardware and software optimizations to train your TensorFlow, MXNet, and PyTorch models with the same speed and efficiency. Model training time directly impacts your ability to iterate and improve on the accuracy of your models quickly.

With algorithms driving purchases and clicks all over the internet, nationwide facial recognition systems starting to come online in foreign nations, and autonomous vehicles on the horizon, there seems to be shroud of fear surrounding anything having to do with AI. Some of these fears are very legitimate, but many of these fears may simply show a lack of understanding of the subject at hand. This article will explain some concepts and terminology of Machine Learning, Deep Learning, and Artificial Intelligence on a surface level, as well as recommending additional reading for a more in-depth look at this subject. Any computer system that mimics the way humans make decisions can be considered Artificial Intelligence, no matter how primitive its systems are. If a programmer created a massive decision tree of if/else statements to try and diagnose patients that were sick, it probably wouldn't do a very good job, but it would still be considered artificial intelligence.

Natural Language Processing or NLP is an area of Data Science, Machine Learning and Linguistics which focuses on processing the language that people speak. NLP used to be one of the slowest developing areas. When Computer Vision has been using fancy neural networks since the dawn of AlexNet, NLP was lagging behind. In recent years the area is starting to get closer and closer to the development speed of CV. You might have heard about the Transformer, BERT, XLnet, and Ernie. What is NLP overall, how do machines understand our speech, and do they?

Today, I'll try to give some insights about TDA (for Topological Data Analysis), a mathematical field quickly evolving, that will certainly soon be completely integrated into machine-/deep- learning frameworks. Some use-cases will be presented in the wake of this article, in order to illustrate the power of that theory! Topological Data Analysis, also abbreviated TDA, is a recent field that emerged from various works in applied topology and computational geometry. It aims at providing well-founded mathematical, statistical and algorithmic methods to exploit the topological and underlying geometric structures in data. You will generally find it suitable for three-dimensional data, but experience shows that TDA reveals also to be useful in other cases, such as time-series.

WHAT: Computers are gradually thinking like humans thanks to the development of artificial intelligence networks capable of learning on their own, called "deep learning." These networks can already recognize images and play chess, for example. But in comparison to the human brain, deep learning can require up to 1,000 times more energy to perform the same functions. This means that if smart glasses used deep learning to recognize objects, the battery would last only 25 minutes, studies have shown. In a perspective paper published in Nature, Purdue University researchers recommend that deep-learning networks mimic electrical signals in the brain, called "spikes," to be more energy efficient.

The only reason many are speaking about AGI with some credulity is due to deep learning. Other approaches: decision trees, graph models, kernel models and symbols have not moved the needle in the past decade.

One of the most important factors driving Python's popularity as a statistical modeling language is its widespread use as the language of choice in data science and machine learning. Today, there's a huge demand for data science expertise as more and more businesses apply it within their operations. Python offers the right mix of power, versatility, and support from its community to lead the way. It's worth noting, however, that sound statistical modeling occupies a central role in a data science stack, but some statistical modeling fundamentals often get overlooked, leading to poor analysis and bad decisions. This article covers some of the essential statistical modeling frameworks and methods for Python, which can help us do statistical modeling and probabilistic computation.
