Retrocomputing: Replacing a 386/486 CMOS Battery

Older 386/486 motherboards often have leaky NiCd or NiMH batteries that can damage the board. This guide details a simple alternative: using three AA batteries and a battery holder. The author compares using a CR2032 and a Tadrian 3.6V Lithium cell, ultimately opting for three AAs due to ease of use, no motherboard modification, and the ability to use rechargeable batteries. Other replacement methods are mentioned, including using a CR2032 holder and Schottky diode, and utilizing an external battery header on the motherboard if present.

Efficient Fine-tuning: A Deep Dive into LoRA (Part 1)

Fine-tuning large language models typically requires substantial computational resources. This article introduces LoRA, a parameter-efficient fine-tuning technique. LoRA significantly reduces the number of parameters needing training by inserting low-rank matrices as adapters into a pre-trained model, thus lowering computational and storage costs. This first part explains the principles behind LoRA, including the shortcomings of traditional fine-tuning, the advantages of parameter-efficient methods, and the mathematical basis of low-rank approximation. Subsequent parts will delve into the specific implementation and application of LoRA.

Adversarial Policies Defeat Superhuman Go AIs

2024-12-24

Researchers achieved a >97% win rate against the state-of-the-art Go AI, KataGo, by training adversarial policies. These adversaries didn't win by playing Go well, but by tricking KataGo into making critical blunders. The attack transferred zero-shot to other superhuman Go AIs and was simple enough for human experts to replicate without algorithmic assistance. The vulnerability persisted even after KataGo was adversarially trained to defend against it, highlighting surprising failure modes in even superhuman AI systems.

INFP: An Audio-Driven Interactive Head Generation Framework for Natural Dyadic Conversations

2024-12-22

ByteDance introduces INFP, a novel audio-driven interactive head generation framework. Given dual-track audio from a dyadic conversation and a single portrait image, INFP dynamically synthesizes realistic agent videos with verbal, nonverbal, and interactive cues, including lifelike facial expressions and head movements. The lightweight framework is ideal for real-time communication like video conferencing. INFP uses a two-stage process: Motion-Based Head Imitation and Audio-Guided Motion Generation. The first stage projects facial communicative behaviors into a low-dimensional latent space, while the second maps dyadic audio to these codes, enabling audio-driven generation. A new large-scale dyadic conversation dataset, DyConv, is also introduced. INFP achieves superior performance and natural interaction.

AI-Powered Crossword Generation: A Breakthrough

2024-12-23

Bill Moorier, a programmer, has been developing computer programs to generate crosswords for years. Recently, incorporating modern AI techniques, he's achieved remarkable results, producing crosswords that rival human-created ones. His approach combines traditional computer science algorithms and modern AI models. It begins with a massive wordlist, refined by AI to remove obscure terms. A grid with 180-degree rotational symmetry is then generated, filled with words using a backtracking search algorithm. Finally, a large language model generates clues, with post-processing to avoid revealing the answers. The system currently generates a complete crossword roughly every two minutes, though imperfections remain, such as occasional clue leakage (especially with acronyms). Future plans include themed crosswords, a significant challenge in crossword generation.

Artist Trains Rats to Predict Forex Markets

Austrian conceptual artist Michael Marcovici's project, "Rat Traders," trained rats to predict foreign exchange futures prices. He converted price fluctuations into piano notes, and the rats predicted subsequent note changes. Surprisingly, trained rats seemingly outperformed human traders after months, though this lacked rigorous statistical testing. Marcovici's project satirizes the belief in market prediction and the human desire for shortcuts to profit in a chaotic system. The project ultimately ended due to rats' limited trading capacity, highlighting the unreliability of market prediction.

Earth's Subsurface May Hold Vast Reserves of Natural Hydrogen

Two geologists from the U.S. Geological Survey have developed a model suggesting Earth's subsurface may contain up to 5.6 × 10⁶ million metric tons of natural hydrogen. The model incorporates factors like natural production rates, reservoir amounts, and leakage from hydrogen-bearing rocks. While most of this hydrogen is likely inaccessible, the researchers highlight that harvesting just 2% could meet humanity's energy needs for roughly two centuries, offering a potential game-changer for clean energy.

Scientists 'Write' New Information into the Human Brain Using MRI

Researchers from the University of Rochester, Yale University, and Princeton University have developed a novel technique to induce learning by directly manipulating brain activity patterns. Using real-time brain imaging and neurofeedback, this method bypasses traditional learning processes that require effort and practice. Participants in an fMRI machine were presented with 'wobbling' abstract shapes and instructed to stop the movement using only their minds. A pre-defined brain activity pattern associated with a new visual category was linked to cessation of the wobble. This feedback mechanism effectively 'sculpted' the participants' brain activity, leading them to learn new visual categories without conscious awareness. This groundbreaking technology holds immense potential for applications in education, rehabilitation, and mental health treatments.

While Allied forces utilized the Autobahn in the later stages of WWII, this wasn't its original intent. The article debunks the myth that the US Interstate system was designed with one mile in five being straight and level for emergency bomber landings, explaining its true purpose was civilian benefit and economic development, although it also served military needs, such as troop movement and industrial production. Finally, the article reviews post-WWII attempts and exercises by various militaries to utilize highways as emergency runways for aircraft, highlighting their limitations and ultimate replacement by dedicated airfields.

The Centers for Disease Control and Prevention (CDC) has confirmed the first case of severe bird flu in the United States. A Louisiana resident over 65 with underlying health conditions is hospitalized with severe respiratory illness due to avian influenza. The patient had contact with backyard birds, and genomic data shows the virus strain matches one recently spreading in US wild birds and poultry. While 61 human cases have been reported in the US since April, most were mild and recovered with antiviral treatment. The CDC stresses the risk of human-to-human transmission is low, but advises precautions for those working with or around poultry.
