Real-time Neuroplasticity: Giving Pre-trained LLMs Real-time Learning

2025-04-08

Real-time Neuroplasticity: Giving Pre-trained LLMs Real-time Learning

This experimental technique, called "Neural Graffiti," uses a plug-in called the "Spray Layer" to inject memory traces directly into the final inference stage of pre-trained large language models (LLMs) without fine-tuning or retraining. Mimicking the neuroplasticity of the brain, it subtly alters the model's "thinking" by modifying vector embeddings, influencing its generative token predictions. Through interaction, the model gradually learns and evolves. While not forcing specific word outputs, it biases the model towards associated concepts with repeated interaction. The aim is to give AI models more proactive behavior, focused personality, and enhanced curiosity, ultimately helping them achieve a form of self-awareness at the neuron level.

LLM Elimination Game: Social Reasoning, Strategy, and Deception

2025-04-07

LLM Elimination Game: Social Reasoning, Strategy, and Deception

Researchers created a multiplayer "elimination game" benchmark to evaluate Large Language Models (LLMs) in social reasoning, strategy, and deception. Eight LLMs compete, engaging in public and private conversations, forming alliances, and voting to eliminate opponents until only two remain. A jury of eliminated players then decides the winner. Analyzing conversation logs, voting patterns, and rankings reveals how LLMs balance shared knowledge with hidden intentions, forging alliances or betraying them strategically. The benchmark goes beyond simple dialogue, forcing models to navigate public vs. private dynamics, strategic voting, and jury persuasion. GPT-4.5 Preview emerged as the top performer.

mem-isolate: Safely Running Unsafe Code

mem-isolate executes your function via a fork(), waits for the result, and returns it to the parent process, preventing unsafe code from affecting the parent's memory footprint. It handles memory leaks and heap fragmentation, enforcing memory purity even for impure functions. Currently supporting only Unix-like systems, it adds approximately 1ms overhead compared to direct function calls—a reasonable trade-off for memory safety in critical applications.

Erica Synths Opensources its DIY Eurorack Modules

Following the discontinuation of its legacy DIY eurorack projects, Erica Synths has decided to open-source them. They've provided Gerber files for PCB-made front panels and made slight design changes to eliminate custom and rare components (though some modules still require rare ICs available at www.ericasynths.lv). Each folder contains complete build information and files: schematics, front panel Gerber files, PCB Gerber files, BOMs, component placement with values and designators, and assembly manuals (note that some manuals are for older module versions). Erica Synths permits third-party use for personal, educational, or commercial purposes, but will provide no support; refer to forums (www.muffwiggler.com) for build nuances, troubleshooting, part availability, and alternatives. Open-sourced modules include: Bassline, BBD delay/flanger, Delay, Dual VCA, Envelope, MIDI-CV, Mixer, Modulator, Output, Polivoks VCF, Swamp, and VCO3.

Topological Sort Algorithm Variant: Efficiently Handling Dependencies

This article presents an improved topological sorting algorithm based on Kahn's algorithm, but it treats nodes as sets instead of individual nodes. The algorithm iteratively finds the root sets of the graph, removes them, and repeats until the graph is empty. The order of the removed root sets forms a topological order, and nodes within the same root set are independent and can be processed in parallel. The algorithm can also detect cycles and return a partial topological ordering instead of completely aborting.
