new fast.ai course: A Code-First Introduction to Natural Language Processing

Today we are releasing a new course (taught by me), Deep Learning from the Foundations, which shows how to build a state of the art deep learning model from scratch.

It takes you all the way from the foundations of implementing matrix multiplication and back-propogation, through to high performance mixed-precision training, to the latest neural network architectures and learning techniques, and everything in between.

It covers many of the most important academic papers that form the foundations of modern deep learning, using “code-first” teaching, where each method is implemented from scratch in python and explained in detail (in the process, we’ll discuss many important software engineering techniques too).

The whole course, covering around 15 hours of teaching and dozens of interactive notebooks, is entirely free (and ad-free), provided as a service to the community.

It is the latest in our ongoing commitment to providing free, practical, cutting-edge education for deep learning practitioners and educators—a commitment that has been appreciated by hundreds of thousands of students, led to The Economist saying “Demystifying the subject, to make it accessible to anyone who wants to learn how to build AI software, is the aim of Jeremy Howard… It is working”, and to CogX awarding fast.ai the Outstanding Contribution in AI award.

huge amount of work went into the last two lessons—not only did the team need to create new teaching materials covering both TensorFlow and Swift, but also create a new fastai Swift library from scratch, and add a lot of new functionality (and squash a few bugs!) in Swift for TensorFlow.

It was a very close collaboration between Google Brain’s Swift for TensorFlow group and fast.ai, and wouldn’t have been possible without the passion, commitment, and expertise of the whole team, from both Google and fast.ai.

We’ll then use this to create a basic neural net forward pass, including a first look at how neural networks are initialized (a topic we’ll be going into in great depth in the coming lessons).

Finally, we develop a new kind of normalization layer to overcome these problems, compare it to previously published approaches, and see some very encouraging results.

We’ll look closely at each step: Next up, we build a new StatefulOptimizer class, and show that nearly all optimizers used in modern deep learning training are just special cases of this one class.

We develop a new GPU-based data augmentation approach which we find speeds things up quite dramatically, and allows us to then add more sophisticated warp-based transformations.

We implement some really important training techniques in lesson 12, all using callbacks: We also implement xresnet, which is a tweaked version of the classic resnet architecture that provides substantial improvements.

Finally, we show how to implement ULMFiT from scratch, including building an LSTM RNN, and looking at the various steps necessary to process natural language data to allow it to be passed to a neural network.

He shares insights on its development history, and why he thinks it’s a great fit for deep learning and numeric programming more generally.

Thanks to the compilation and language design, basic code runs very fast indeed - about 8000 times faster than Python in the simple example Chris showed in class.

He shows how to use this to quickly and easily get high performance code by interfacing with existing C libraries, using Sox audio processing, and VIPS and OpenCV image processing as complete working examples.

So be sure to study the notebooks to see lots more Swift tricks… We’ll be releasing even more lessons in the coming months and adding them to an attached course we’ll be calling Applications of Deep Learning.

11 Artificial Intelligence Interview Questions to Prep for Ahead of Time

Once the stuff of science fiction novels and futuristic movies, Artificial Intelligence (AI) is now very real to us.

Almost 60 percent (57.9) of organizations with Big Data solutions are using AI in some way, it’s predicted that AI and machine learning will impact all segments of our daily lives by 2025 with huge implications for industries ranging from transport and logistics to healthcare, home maintenance, and customer service.

Read More: Understanding Artificial Intelligence With that dramatic increase in reliance on AI, heavy investments are being made in both the technology and the skilled professionals needed to enable implementing and benefitting from the technology.

Meaning, the need for professionals skilled in Artificial Intelligence exists in just about every field imaginable which leads to a strong job outlook and high-paying salaries.

According to Indeed.com, the average salary for a professional with an AI certification is $110k a year in the U.S. Growing adoption, increased demand for certified professionals and solid salaries make a move into AI a wise choice for someone interested in this career field.

Whether you’re considering a career move into the AI domain, or you’re already there and want to move up the career ladder, the future looks bright.

To position yourself for success as a job candidate who stands out from the crowd, you should be pursuing certifications in AI, as well as, preparing ahead of time for crucial job AI interview questions.

Your answer here should show that you recognize the far-reaching and practical applications of AI, but your answer is up to you because your personal understanding of the AI field is what the interviewer is trying to ascertain.

Possibilities include contract analysis, object detection, and classification for avoidance and/or navigation, image recognition, content distribution, predictive maintenance, data processing, automation of manual tasks or data-driven reporting.

It refers to using multi-layered neural networks to process data in increasingly complex ways, enabling the software to train itself to perform tasks like speech and image recognition through exposure to these vast amounts of data, for continual improvement in the ability to recognize and process information.

Image recognition also helps machines to learn (as in machine learning) because the more images that are processed, the better the software gets at recognizing and processing those images.

Supervised learning is a machine learning process in which outputs are fed back into a computer for the software to learn from, for more accurate results the next time.

Artificial intelligence learns, in part, using “if-then” rules, so if you’re not sure your AI education is at the level it should be before you start job hunting, then consider pursuing certification in AI or even a masters program that can prepare you for a career as an Artificial Intelligence Engineer.

OpenAI

Nevertheless, Sutskever stated that he was willing to leave Google for OpenAI “partly of because of the very strong group of people and, to a very large extent, because of its mission.” Brockman stated that “the best thing that I could imagine doing was moving humanity closer to building real AI in a safe way.” OpenAI researcher Wojciech Zaremba stated that he turned down “borderline crazy” offers of two to three times his market value to join OpenAI instead.&#91;7&#93;

and which sentiment has been expressed elsewhere in reference to a potentially enormous class of AI-enabled products: 'Are we really willing to let our society be infiltrated by autonomous software and hardware agents whose details of operation are known only to a select few?

Vishal Sikka, former CEO of Infosys, stated that an “openness” where the endeavor would “produce results generally in the greater interest of humanity” was a fundamental requirement for his support, and that OpenAI “aligns very nicely with our long-held values” and their “endeavor to do purposeful work”.&#91;25&#93;

We could sit on the sidelines or we can encourage regulatory oversight, or we could participate with the right structure with people who care deeply about developing AI in a way that is safe and is beneficial to humanity.” Musk acknowledged that “there is always some risk that in actually trying to advance (friendly) AI we may create the thing we are concerned about”;

During a 2016 conversation about the technological singularity, Altman said that “we don’t plan to release all of our source code” and mentioned a plan to “allow wide swaths of the world to elect representatives to a new governance board”.

Gym aims to provide an easy-to-setup general-intelligence benchmark with a wide variety of different environments—somewhat akin to, but broader than, the ImageNet Large Scale Visual Recognition Challenge used in supervised learning research—and that hopes to standardize the way in which environments are defined in AI research publications, so that published research becomes more easily reproducible.&#91;8&#93;&#91;29&#93;

when an agent is then removed from this virtual environment and placed in a new virtual environment with high winds, the agent braces to remain upright, suggesting it had learned how to balance in a generalized way.&#91;32&#93;&#91;33&#93;

OpenAI Five is the name of a team of five OpenAI-curated bots that are used in the competitive five-on-five video game Dota 2, who learn to play against human players at a high skill level entirely through trial-and-error algorithms.

Before becoming a team of five, the first public demonstration occurred at The International 2017, the annual premiere championship tournament for the game, where Dendi, a professional Ukrainian player of the game, lost against a bot in a live 1v1 matchup.&#91;36&#93;&#91;37&#93;

After the match, CTO Greg Brockman explained that the bot had learned by playing against itself for two weeks of real time, and that the learning software was a step in the direction of creating software that can handle complex tasks like a surgeon.&#91;38&#93;&#91;39&#93;

The system uses a form of reinforcement learning, as the bots learn over time by playing against themselves hundreds of times a day for months, and are rewarded for actions such as killing an enemy and taking map objectives.&#91;40&#93;&#91;41&#93;&#91;42&#93;
