Production data labeling workflows

It’s one thing to gather some labels for your data. It’s another thing to integrate data labeling into your workflows and infrastructure in a scalable, secure, and useful way. Mark from Xelex joins us to talk through some of what he has learned after helping companies scale their data annotation efforts. We get into workflow management, labeling instructions, team dynamics, and quality assessment. This is a super practical episode!

OpenAI introduces Whisper (open source speech recognition)

They’re really putting the Open in OpenAI with this one…

Whisper is an automatic speech recognition (ASR) system trained on 680,000 hours of multilingual and multitask supervised data collected from the web. We show that the use of such a large and diverse dataset leads to improved robustness to accents, background noise and technical language. Moreover, it enables transcription in multiple languages, as well as translation from those languages into English. We are open-sourcing models and inference code to serve as a foundation for building useful applications and for further research on robust speech processing.

We might need to give this a spin on our transcripts. Who knows, maybe our next big innovation could be The Changelog in German, French, Spanish, etc!

Stable Diffusion breaks the internet

This week on The Changelog we’re talking about Stable Diffusion, DALL-E, and the impact of AI generated art. We invited our good friend Simon Willison on the show today because he wrote a very thorough blog post titled, “Stable Diffusion is a really big deal.”

You may know Simon from his extensive contributions to open source software. Simon is a co-creator of the Django Web framework (which we don’t talk about at all on this show), he’s the creator of Datasette, a multi-tool for exploring and publishing data (which we do talk about on this show)…most of all Simon is a very insightful thinker, which he puts on display here on this episode. We talk from all the angles of this topic, the technical, the innovation, the future and possibilities, the ethical and the moral – we get into it all. The question is, will this era be known as the initial push back to the machine?

Stable Diffusion

The new stable diffusion model is everywhere! Of course you can use this model to quickly and easily create amazing, dream-like images to post on twitter, reddit, discord, etc., but this technology is also poised to be used in very pragmatic ways across industry. In this episode, Chris and Daniel take a deep dive into all things stable diffusion. They discuss the motivations for the work, the model architecture, and the differences between this model and other related releases (e.g., DALL·E 2).

Licensing & automating creativity

AI is increasingly being applied in creative and artistic ways, especially with recent tools integrating models like Stable Diffusion. This is making some artists mad. How should we be thinking about these trends more generally, and how can we as practitioners release and license models anticipating human impacts? We explore this along with other topics (like AI models detecting swimming pools 😊) in this fully connected episode.

Responding to recruiter emails with GPT-3

Like many software engineers, Matt Bilyeu receives multiple emails from recruiters weekly. And, because he’s polite (and for other reasons) he tries to respond (politely) to all of them. But…

It would be ideal if I could automate sending these responses. Assuming I get four such emails per week and that it takes two minutes to read and respond to each one, automating this would save me about seven hours of administrative work per year.

Enter the GPT-3 API and some code that gets run by a future cron job (now that he’s tested this on a handful of emails) and Matt auto-responds to al the emails, continues to be polite, while also saving (his) time. It’s AI Matt responding the way real Matt would.

Stable Diffusion is a really big deal

Simon Willison explains what it is:

Stable Diffusion is a new “text-to-image diffusion model” that was released to the public by Stability.ai six days ago, on August 22nd.

It’s similar to models like Open AI’s DALL-E, but with one crucial difference: they released the whole thing.

And why it’s a really big deal:

In just a few days, there has been an explosion of innovation around it. The things people are building are absolutely astonishing.

He then details some of the innovation and it is staggering, to say the least. Open FTW!

Privacy in the age of AI

In this Fully-Connected episode, Daniel and Chris discuss concerns of privacy in the face of ever-improving AI / ML technologies. Evaluating AI’s impact on privacy from various angles, they note that ethical AI practitioners and data scientists have an enormous burden, given that much of the general population may not understand the implications of the data privacy decisions of everyday life.

This intentionally thought-provoking conversation advocates consideration and action from each listener when it comes to evaluating how their own activities either protect or violate the privacy of those whom they impact.

Practical, positive uses for deep fakes

Differentiating between what is real versus what is fake on the internet can be challenging. Historically, AI deepfakes have only added to the confusion and chaos, but when labeled and intended for good, deepfakes can be extremely helpful. But with all of the misinformation surrounding deepfakes, it can be hard to see the benefits they bring. Lior Hakim, CTO at Hour One, joins Chris and Daniel to shed some light on the practical uses of deepfakes. He addresses the AI technology behind deepfakes, how to make positive use of deep fakes such as breaking down communications barriers, and shares how Hour One specializes in the development of virtual humans for use in professional video communications.

The AI art apocalypse

Alexander Wales:

This image was created by an AI, MidJourney. All I had to do was type in a prompt (“wildfire”) and aspect ratio. This AI is pretty good, but nowhere near the state of the art, and AI like it are, over the next few years, going to make art like this available within seconds at a cost of pennies. This applies not just to “art” like the above, which is going to accompany my prose and worldbuilding projects, but to almost every area of life where you see pictures of any kind. I think it’s hard to understate how big of a deal this will end up being, and this blog post is largely my attempt to collate a lot of the arguments under one roof, in part because some of the arguments aren’t actually arguments at all.

AI's role in reprogramming immunity

Drausin Wulsin, Director of ML at Immunai, joins Daniel & Chris to talk about the role of AI in immunotherapy, and why it is proving to be the foremost approach in fighting cancer, autoimmune disease, and infectious diseases.

The large amount of high dimensional biological data that is available today, combined with advanced machine learning techniques, creates unique opportunities to push the boundaries of what is possible in biology.

To that end, Immunai has built the largest immune database called AMICA that contains tens of millions of cells. The company uses cutting-edge transfer learning techniques to transfer knowledge across different cell types, studies, and even species.

A human-in-the-loop workflow for creating HD images from text

DALL-E can generate some amazing results, but we’re still in a phase of AI’s progress where having humans involved in the process is just better. Here’s how the authors of this workflow explain it:

Generative art is a creative process. While recent advances of DALL·E unleash people’s creativity, having a single-prompt-single-output UX/UI locks the imagination to a single possibility, which is bad no matter how fine this single result is. DALL·E Flow is an alternative to the one-liner, by formalizing the generative art as an iterative procedure.
