Practical AI Practical AI #166

Exploring deep reinforcement learning

In addition to being a Developer Advocate at Hugging Face, Thomas Simonini is building next-gen AI in games that can talk and have smart interactions with the player using Deep Reinforcement Learning (DRL) and Natural Language Processing (NLP). He also created a Deep Reinforcement Learning course that takes a DRL beginner to from zero to hero. Natalie and Chris explore what’s involved, and what the implications are, with a focus on the development path of the new AI data scientist.

New Mac day!

We upgraded to the new MacBook Pro M1 Max and decided to share our first impressions of the new hardware, how we migrate data and settings from our old machines (or don’t), which apps were “instant installs” for each of us, which apps we’re trying to live without, and how we get our new machines set up for work and play. Nerd out with us!

The mathematics of machine learning

Tivadar Danka is an educator and content creator in the machine learning space, and he is writing a book to help practitioners go from high school mathematics to mathematics of neural networks. His explanations are lucid and easy to understand. You have never had such a fun and interesting conversation about calculus, linear algebra, and probability theory before!

The $1 trillion dollar ML model 💵

American Express is running what is perhaps the largest commercial ML model in the world; a model that automates over 8 billion decisions, ingests data from over $1T in transactions, and generates decisions in mere milliseconds or less globally. Madhurima Khandelwal, head of AMEX AI Labs, joins us for a fascinating discussion about scaling research and building robust and ethical AI-driven financial applications.

It's OK to self-care

Most of us have heard how important “self-care” is and how important it can be for healthy living. But what exactly IS self-care? In this episode, not only do we define what self-care is, but we talk through the physical, emotional, and spiritual aspects of what’s involved in self-care and why this can so often be misunderstood and challenging. While we might be familiar with this term, many may not consider how they can be deliberate around managing themselves by both reflecting on and engaging in activities that help support their brains and bodies. It isn’t enough to simply know that self-care is important, rather discovering practical actions you can take to improve both how you feel and how you engage with the world.

Brain Science Brain Science #28

Dealing with conflict

Conflict is a part of everyday life. If you are connected to other humans, conflict will eventually occur. But what exactly is conflict? Where does it begin? How can it be resolved? In this episode, Mireille and Adam dive deep into those details to examine the framework of conflict end-to-end, to hopefully equip us with the tactics and skills we need to better navigate and resolve the conflict we encounter in our lives.

Getting Waymo into autonomous driving

Waymo’s mission is to make it safe and easy for people and things to get where they’re going.
After describing the state of the industry, Drago Anguelov - Principal Scientist and Head of Research at Waymo - takes us on a deep dive into the world of AI-powered autonomous driving. Starting with Waymo’s approach to autonomous driving, Drago then delights Daniel and Chris with a tour of the algorithmic tools in the autonomy toolbox.

Hidden Door and so much more

Hilary Mason is building a new way for kids and families to create stories with AI. It’s called Hidden Door, and in her first interview since founding it, Hilary reveals to Chris and Daniel what the experience will be like for kids. It’s the first Practical AI episode in which some of the questions came from Chris’s 8yo daughter Athena.

Hilary also shares her insights into various topics, like how to build data science communities during the COVID-19 Pandemic, reasons why data science goes wrong, and how to build great data-based products. Don’t miss this episode packed with hard-won wisdom!

Brain Science Brain Science #25

The science behind caffeine

Today’s episode features our very first guest. We’re joined by Danielle Rath, a notable expert and product developer in the caffeine and energy drink industry. Danielle is the founder of GreenEyedGuide Research and Consulting where she shares science-based information about energy drinks and caffeine, and helps people and companies where fatigue and caffeine use are prevalent. In this lengthly episode, we talk through all aspects of the science behind caffeine — its chemical structure and half-life, where and how it’s being used, the good, bad, and the ugly, as well as practical advice for everyday consumption. If you consume caffeine of any sort, this is a must listen episode.

Achieving provably beneficial, human-compatible AI

AI legend Stuart Russell, the Berkeley professor who leads the Center for Human-Compatible AI, joins Chris to share his insights into the future of artificial intelligence. Stuart is the author of Human Compatible, and the upcoming 4th edition of his perennial classic Artificial Intelligence: A Modern Approach, which is widely regarded as the standard text on AI. After exposing the shortcomings inherent in deep learning, Stuart goes on to propose a new practitioner approach to creating AI that avoids harmful unintended consequences, and offers a path forward towards a future in which humans can safely rely of provably beneficial AI.

Working from home

Given all of the recent changes and adjustments many individuals have made to working remotely, Mireille and Adam discuss some of the relevant aspects of working from home. How do you develop habits that work for you to be the most productive? Which factors make a difference to be successful in navigating challenges that emerge and how can you develop ways of staying socially connected while being physically distant?

Brain Science Brain Science #14

Memory and learning

Mireille and Adam discuss the process of forming memories, the various types of memory, anxieties, phobias, panic attacks, and how our attention and our memory relates to learning. Where you place your attention influences what you might remember. What you are able to remember influences how you feel, the choices you make, and your future outcomes.

Brain Science Brain Science #11

Competing for attention

Mireille and Adam discuss the mechanism of attention as an allocation of one’s resources. If we can think of attention as that of a lens, we can practice choosing what we give our attention to recognizing that multiple things, both externally and internally, routinely compete for our attention. Distraction can also be useful when we utilize it intentionally to manage the focus of our attention.

Brain Science Brain Science #3

Humans and habits

Mireille and Adam explore the habit loop, the role of environment as a cue, behavior change, the role of dopamine, willpower as a finite resource, and the impact of social influences on habits.

As with any change, we need to collect data. Instead of trying to change a habit right away, treat yourself like a scientist in a data gathering stage and experiment with different rewards to better understand your habit loops. Making and breaking a habit is different for everyone.

Exposing the deception of DeepFakes

This week we bend reality to expose the deceptions of deepfake videos. We talk about what they are, why they are so dangerous, and what you can do to detect and resist their insidious influence. In a political environment rife with distrust, disinformation, and conspiracy theories, deepfakes are being weaponized and proliferated as the latest form of state-sponsored information warfare. Join us for an episode scarier than your favorite horror movie, because this AI bogeyman is real!

OpenAI's new "dangerous" GPT-2 language model

This week we discuss GPT-2, a new transformer-based language model from OpenAI that has everyone talking. It’s capable of generating incredibly realistic text, and the AI community has lots of concerns about potential malicious applications. We help you understand GPT-2 and we discuss ethical concerns, responsible release of AI research, and resources that we have found useful in learning about language models.

Suz Hinton says find your allies

Almost eight years ago, Suz Hinton made one of the biggest decisions of her life: move away from her home in Melbourne, Australia and move to the United States. After amicably breaking up with her boyfriend, another decision lied ahead: would she stay?

Suz talks to me about culture shock, the hoops she had to jump through to get her visa, her parents, and dealing with burnout.
