ReRAM-based Neo-Hebbian Synapses For Training Neuromorphic HW (IIT Madras, UCSB)

Researchers from IIT Madras and UC Santa Barbara have published a technical paper introducing a novel NeoHebbian artificial synapse using ReRAM devices for neuromorphic systems. This synapse incorporates two state variables: a neuron coupling weight and an "eligibility trace" for synaptic weight updates. The coupling weight is encoded in ReRAM conductance, while the "eligibility trace" is encoded in local temperature modulated by voltage pulses. The synapse was tested for tasks like temporal signal classification and reinforcement learning, showing promise for efficient implementation of advanced learning rules in neuromorphic hardware.

PewDiePie goes all-in on self-hosting AI using modded GPUs, with plans to build his own model soon — YouTuber pits multiple chatbots against each other to find the best answers

PewDiePie has ventured into self-hosting AI models, creating a custom web UI called "ChatOS" and using a powerful PC with multiple GPUs to run open-source models from Baidu and OpenAI. He built a "council" of chatbots for voting on responses and developed "The Swarm" for data collection, leading to plans for his own AI model. Additionally, he donated compute power to Folding@home for medical research and explored running AI models on his system. Despite some experimentation challenges, PewDiePie demonstrated the potential of smaller, efficient AI models and hinted at sharing his setup for self-hosting AI in the future.

MindsEye's sabotage mission is being slammed as dull and pointless

Build A Rocket Boy accuses individuals of sabotaging MindsEye's launch, spending over €1 million on damaging efforts. The studio integrates the controversy into a new in-game mission, Blacklist, to showcase evidence of sabotage to players. However, reports describe the mission as lackluster and failing to deliver a compelling narrative. Critics attribute the launch issues to internal problems, such as management and design decisions, casting doubt on the sabotage claims. The saga continues as MindsEye's post-launch turmoil unfolds.
