This AI Model Can Intuit How the Physical World Works

WIRED

As the engineers who build self-driving cars know, it can be hard to get an AI system to reliably make sense of what it sees. Most systems designed to "understand" videos in order to either classify their content ("a person playing tennis," for example) or identify the contours of an object--say, a car up ahead--work in what's called "pixel space." The model essentially treats every pixel in a video as equal in importance. But these pixel-space models come with limitations. Imagine trying to make sense of a suburban street. If the scene has cars, traffic lights and trees, the model might focus too much on irrelevant details such as the motion of the leaves. It might miss the color of the traffic light, or the positions of nearby cars. "When you go to images or video, you don't want to work in [pixel] space because there are too many details you don't want to model," said Randall Balestriero, a computer scientist at Brown University. Yann LeCun, a computer scientist at New York University and the director of AI research at Meta, created JEPA, a predecessor to V-JEPA that works on still images, in 2022.


Vampire: The Masquerade Bloodlines 2 review – an interestingly toothless piece of noir fiction

The Guardian

'A 25-hour story that just about makes sense' Vampire: The Masquerade Bloodlines 2. 'A 25-hour story that just about makes sense' Vampire: The Masquerade Bloodlines 2. Y ou are an ancient and powerful vampire, and you wake up in the basement of some decrepit Seattle building, with no recent memories and a strange sigil on your hand. The first thing you do is feed on the cop who finds you, before smacking his partner into a wall so hard that his blood spatters the brick. A violent fanged rampage ensues, where you beat up and tear apart rival undead and their ghouls while currying the favour of the local court of vampires, and trying to keep your existence hidden from the mortal populace of this sultry city. But this is also a detective story: there's a younger night-stalker sharing your brain, a voice in your head named Fabian, who talks like a 1920s gumshoe (presumably because he once was one). Fabian isn't violent at all; he evidently works with the human police and the vampire underworld, snacking on consenting volunteers' blood and using his mind-delving powers to solve murders.


Multiview Aggregation for Learning Category-Specific Shape Reconstruction

Neural Information Processing Systems

We thank the reviewers for their valuable comments, and are happy to see feedback such as "concepts presented The reviewers agree that NOX maps are "definitely novel We answer questions, address factual errors, and present more details to improve our manuscript. The differences in chairs between Table 4 and 5 are due to different experimental setting. "Fixed Multi" models were trained with 2, 3, or 5 views respectively. We will add this detail in the paper. "Dated" methods are still valid prior art to compare against especially when We choose to only use the first and last intersections due to computational efficiency.

Using Generative AI for therapy might feel like a lifeline – but there's danger in seeking certainty in a chatbot

The Guardian

Tran* sat across from me, phone in hand, scrolling. "I just wanted to make sure I didn't say the wrong thing," he explained, referring to a disagreement with his partner. "So I asked ChatGPT what I should say." He read the chatbot-generated message aloud. It was articulate, logical and composed – too composed.


The AI Mirage

The Atlantic - Technology

"I'm not going to respond to that," Siri responded. I had just cursed at it, and this was my passive-aggressive chastisement. The cursing was, in my view, warranted. I was in my car, running errands, and had found myself in an unfamiliar part of town. I requested "directions to Lowe's," hoping to get routed to the big-box hardware store without taking my eyes off the road.


Reviews: Scalable Structure Learning of Continuous-Time Bayesian Networks from Incomplete Data

Neural Information Processing Systems

Summary: Within the manuscript, the authors extend the continuous time Bayesian Networks by incorporating a mixture prior over the conditional intensity matrices, thereby allowing for a larger class compared to a gamma prior usually employed over these. My main concerns are with clarity / quality as the manuscript is quite densely written with quite some material has either been omitted or shifted to the appendix. For a non-expert in continuous time bayesian networks, it is quite hard to read. Additionally, there are quite a few minor mistakes (see below) that make understanding of the manuscript harder. As it stands, Originality: The authors combine variational inference method from Linzner et al [11], with the new prior over the dependency structure (mixture).


How AI is interacting with our creative human processes

MIT Technology Review

The rapid proliferation of AI in our lives introduces new challenges around authorship, authenticity, and ethics in work and art. But it also offers a particularly human problem in narrative: How can we make sense of these machines, not just use them? And how do the words we choose and stories we tell about technology affect the role we allow it to take on (or even take over) in our creative lives? Both Vara's book and The Uncanny Muse, a collection of essays on the history of art and automation by the music critic David Hajdu, explore how humans have historically and personally wrestled with the ways in which machines relate to our own bodies, brains, and creativity. At the same time, The Mind Electric, a new book by a neurologist, Pria Anand, reminds us that our own inner workings may not be so easy to replicate.
