How AI Knows Things No One Told It

Posted by in categories: internet, robotics/AI

At a conference at New York University in March, philosopher Raphaël Millière of Columbia University offered yet another jaw-dropping example of what LLMs can do. The models had already demonstrated the ability to write computer code, which is impressive but not too surprising because there is so much code out there on the Internet to mimic. Millière went a step further and showed that GPT can execute code, too, however. The philosopher typed in a program to calculate the 83rd number in the Fibonacci sequence. “It’s multistep reasoning of a very high degree,” he says. And the bot nailed it. When Millière asked directly for the 83rd Fibonacci number, however, GPT got it wrong: this suggests the system wasn’t just parroting the Internet. Rather it was performing its own calculations to reach the correct answer.

Although an LLM runs on a computer, it is not itself a computer. It lacks essential computational elements, such as working memory. In a tacit acknowledgement that GPT on its own should not be able to run code, its inventor, the tech company OpenAI, has since introduced a specialized plug-in—a tool ChatGPT can use when answering a query—that allows it to do so. But that plug-in was not used in Millière’s demonstration. Instead he hypothesizes that the machine improvised a memory by harnessing its mechanisms for interpreting words according to their context—a situation similar to how nature repurposes existing capacities for new functions.

This impromptu ability demonstrates that LLMs develop an internal complexity that goes well beyond a shallow statistical analysis. Researchers are finding that these systems seem to achieve genuine understanding of what they have learned. In one study presented last week at the International Conference on Learning Representations (ICLR), doctoral student Kenneth Li of Harvard University and his AI researcher colleagues—Aspen K. Hopkins of the Massachusetts Institute of Technology, David Bau of Northeastern University, and Fernanda Viégas, Hanspeter Pfister and Martin Wattenberg, all at Harvard—spun up their own smaller copy of the GPT neural network so they could study its inner workings. They trained it on millions of matches of the board game Othello by feeding in long sequences of moves in text form. Their model became a nearly perfect player.

SpeechGPT? LeMUR AI can turn 10 Hrs SPEECH into LLM Context

Posted by in category: robotics/AI

This is awesome and more than a little scary. You can actually try it on a youtube video and then ask questions about the content…


Introducing LeMUR, AssemblyAI’s new framework for applying powerful LLMs to transcribed speech.
With a single line of code, LeMUR can quickly process audio transcripts for up to 10 hours worth of audio content, which effectively translates into ~150k tokens, for tasks likes summarization and question answer.

High-Resolution Image of the Human Retina Reveals Stunning Details

Posted by in category: genetics

High spatial and temporal resolution

The scientists performed all these analyses on organoids that were of different ages and thus at different stages of development. In this way, they were able to create a time series of images and genetic information that describes the entire 39-week development of retinal organoids.

Intro

In February 2022, Microsoft disabled VBA macros on documents due to their frequent use as a malware distribution method. This move prompted malware authors to seek out new ways to distribute their payloads, resulting in an increase in the use of other infection vectors, such as password-encrypted zip files and ISO files.

Revolutionary Sensor Mimics Human Eye for Vivid Imagery

Posted by in categories: information science, robotics/AI

Summary: Researchers have created a device that emulates the human eye’s ability to see color by using narrowband perovskite photodetectors and a neuromorphic algorithm.

The photodetectors, sensitive to red, green, and blue light, mimic our cone cells, while the neuromorphic algorithm simulates our neural network to process information into high-quality images. Unlike modern cameras that require external filters, this technology could improve resolution and reduce manufacturing costs.

The device also generates electricity as it absorbs light, potentially leading to battery-free camera technology.

SpaceX and Vast Team Up to Create First Private Space Station

Posted by in category: space travel

Haven-1 is scheduled to reach low-Earth orbit aboard a Falcon 9 rocket no earlier than August 2025, and will initially act as an independent crewed station, before connecting to a larger Vast base, currently in development. If all goes well, the Vast-1 mission will then send a four-person crew via SpaceX Dragon to dock with Haven-1 for up to 30 days.

While the International Space Station has at least another seven years of life, plans for Haven-1 represent “the first steps in Vast’s long-term vision of launching much larger, artificial gravity space stations in Earth orbit and beyond,” says Vast CEO Jed McCaleb.

Eventually, Vast plans to develop a 328-foot-long multi-module spinning artificial gravity space station, delivered by SpaceX’s Starship transportation system.
