Neuromorphic computing with memristors: from device to system — Professor Huaqiang Wu

Posted by in categories: information science, robotics/AI

Recently, computation in memory becomes very hot due to the urgent needs of high computing efficiency in artificial intelligence applications. In contrast to von-neumann architecture, computation in memory technology avoids the data movement between CPU/GPU and memory which could greatly reduce the power consumption. Memristor is one ideal device which could not only store information with multi-bits, but also conduct computing using ohm’s law. To make the best use of the memristor in neuromorphic systems, a memristor-friendly architecture and the software-hardware collaborative design methods are essential, and the key problem is how to utilize the memristor’s analog behavior. We have designed a generic memristor crossbar based architecture for convolutional neural networks and perceptrons, which take full consideration of the analog characteristics of memristors. Furthermore, we have proposed an online learning algorithm for memristor based neuromorphic systems which overcomes the varation of memristor cells and endue the system the ability of reinforcement learning based on memristor’s analog behavior.

Researchers propose a smaller, more noise-tolerant quantum factoring circuit for cryptography

Posted by in categories: computing, encryption, information science, quantum physics

The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.

Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring proposed in 1994 by Peter Shor, who is now a professor at MIT.

But while researchers have taken great strides in the last 30 years, scientists have yet to build a quantum computer powerful enough to run Shor’s algorithm.

The circle of life, publish or perish edition: Two journals retract more than 40 papers

Posted by in categories: information science, robotics/AI

The team has released the width-pruned version of the model on Hugging Face under the Nvidia Open Model License, which allows for commercial use. This makes it accessible to a wider range of users and developers who can benefit from its efficiency and performance.

“Pruning and classical knowledge distillation is a highly cost-effective method to progressively obtain LLMs [large language models] of smaller size, achieving superior accuracy compared to training from scratch across all domains,” the researchers wrote. “It serves as a more effective and data-efficient approach compared to either synthetic-data-style fine-tuning or pretraining from scratch.”

This work is a reminder of the value and importance of the open-source community to the progress of AI. Pruning and distillation are part of a wider body of research that is enabling companies to optimize and customize LLMs at a fraction of the normal cost. Other notable works in the field include Sakana AI’s evolutionary model-merging algorithm, which makes it possible to assemble parts of different models to combine their strengths without the need for expensive training resources.

Techno-futurists are selling an interplanetary paradise for the posthuman generation—they just forgot about the rest of us

Posted by in categories: computing, information science

Inside the cult of TESCREALism and the dangerous fantasies of Silicon Valley’s self-appointed demigods, for Document’s Spring/Summer 2024 issue.

As legend has it, Steve Jobs once asked Larry Kenyon, an engineer tasked with developing the Mac computer, to reduce its boot time by 10 seconds. Kenyon said that was impossible. “What if it would save a person’s life?” Jobs asked. Then, he went to a whiteboard and laid out an equation: If 5 million users spent an additional 10 seconds waiting for the computer to start, the total hours wasted would be equivalent to 100 human lifetimes every year. Kenyon shaved 28 seconds off the boot time in a matter of weeks.

Often cited as an example of the late CEO’s “reality distortion field,” this anecdote illustrates the combination of charisma, hyperbole, and marketing with which Jobs convinced his disciples to believe almost anything—elevating himself to divine status and creating “a cult of personality for capitalists,” as Mark Cohen put it in an article about his death for the Australian Broadcasting Corporation. In helping to push the myth of the genius tech founder into the cultural mainstream, Jobs laid the groundwork for future generations of Silicon Valley investors and entrepreneurs who have, amid the global decline of organized religion, become our secular messiahs. They preach from the mounts of Google and Meta, selling the public on digital technology’s saving grace, its righteous ability to reshape the world.

Did AI Just Pass the Turing Test?

Posted by in categories: humor, information science, robotics/AI

A recent study by UC San Diego researchers brings fresh insight into the ever-evolving capabilities of AI. The authors looked at the degree to which several prominent AI models, GPT-4, GPT-3.5, and the classic ELIZA could convincingly mimic human conversation, an application of the so-called Turing test for identifying when a computer program has reached human-level intelligence.

The results were telling: In a five-minute text-based conversation, GPT-4 was mistakenly identified as human 54 percent of the time, contrasted with ELIZA’s 22 percent. These findings not only highlight the strides AI has made but also underscore the nuanced challenges of distinguishing human intelligence from algorithmic mimicry.
