Variational Lossy Autoencoders: When RNNs Ignore Latent Variables

2025-03-09

This paper tackles the challenge of combining Recurrent Neural Networks (RNNs) with Variational Autoencoders (VAEs). While VAEs use latent variables to learn data representations, RNNs as decoders often ignore these latents, directly learning the data distribution. The authors propose Variational Lossy Autoencoders (VLAEs), which restrict the RNN's access to information, forcing it to leverage latent variables for encoding global structure. Experiments demonstrate VLAEs learn compressed and semantically rich latent representations.

Evolving Agents Framework: Collaborative AI Agent Ecosystems

2025-03-09

The Evolving Agents Framework is a production-grade system for building, managing, and evolving AI agents with intelligent communication. It enables collaborative ecosystems of agents that semantically understand requirements, learn from experience, and communicate effectively to solve complex tasks. Key features include agent evolution (reuse, adapt, or create), agent-to-agent communication via a YAML workflow system, a smart library with semantic search powered by OpenAI embeddings, self-improvement through continuous learning, and multi-framework support (BeeAI, OpenAI, etc.). The framework uses a system agent to decide whether to reuse, evolve, or create new agents based on semantic similarity, and includes governance through firmware. A comprehensive example demonstrates agent collaboration and evolution for tasks such as invoice analysis.

AI: Hype vs. Reality – A Technological Shift, Not a Skynet Scenario

2025-03-08

The rapid advancement of AI has sparked widespread concerns about job displacement and even existential threats. This article argues that AI, at its core, is a pattern recognition engine, learning probability distributions from data to make predictions, not truly thinking. While AI achieves impressive results in image generation and text creation, limitations remain, including hallucinations and a lack of genuine logical reasoning. The author draws parallels to past technological shifts, highlighting humanity's adaptability. AI will automate tasks, but also create new opportunities, urging a proactive embrace of change and redirection of human energy towards more meaningful endeavors.

Russian Disinfo Network Infiltrates Western AI Chatbots

2025-03-07

A Moscow-based disinformation network called "Pravda" (Russian for "truth") is infiltrating AI chatbots' data, injecting false claims and propaganda to manipulate their responses to news. By flooding search results with pro-Kremlin falsehoods, the network distorts how large language models process information. This resulted in millions of articles of Russian propaganda being incorporated into Western AI systems, infecting their outputs. NewsGuard's audit of 10 leading AI chatbots revealed they repeated false narratives from the Pravda network 33% of the time. The network doesn't create original content but acts as a laundering machine for Kremlin propaganda, aggregating it across numerous seemingly independent websites. This large-scale operation highlights the vulnerability of AI models to disinformation campaigns.

Beyond Autoregressive Models: The Next Frontier in AI

2025-03-07

Most generative AI models today are autoregressive, meaning they predict the next token, with the transformer architecture being the dominant implementation due to its computational efficiency. However, autoregressive models have inherent limitations, such as a lack of planning and reasoning capabilities, limited long-term memory, and a tendency to "hallucinate." The author argues that human thought isn't purely autoregressive, encompassing non-sequential thinking and planning. To achieve AI closer to human cognition, researchers are exploring alternative paradigms like JEPA and diffusion models, which generate content through iterative refinement or denoising from noise, mirroring human thought processes more closely.

Differentiable Logic Cellular Automata: From Game of Life to Pattern Generation with Learned Recurrent Circuits

2025-03-07

This paper introduces DiffLogic CA, a novel neural cellular automata (NCA) architecture using a fully discrete cell state updated via a learned, recurrent binary circuit. Replacing neural network components with Deep Differentiable Logic Networks allows differentiable training of discrete logic gates. The success of applying differentiable logic gates to cellular automata is demonstrated by replicating Conway's Game of Life and generating patterns through learned discrete dynamics. This highlights the potential of integrating discrete logic within NCAs and proves differentiable logic gate networks can be effectively learned in recurrent architectures. While promising, training for complex shapes remains a challenge, suggesting future work on hierarchical architectures and specialized gates for improved state management.

Diffusion LLMs: A Paradigm Shift in Language Modeling

2025-03-06

Inception Labs has unveiled a groundbreaking Diffusion Large Language Model (dLLM) that challenges the traditional autoregressive approach. Unlike autoregressive models that predict tokens sequentially, dLLMs generate text segments concurrently, refining them iteratively. This method, successful in image and video models, now surpasses similar-sized LLMs in code generation, boasting a 5-10x speed and efficiency improvement. The key advantage? Reduced hallucinations. dLLMs generate and validate crucial parts before proceeding, crucial for applications demanding accuracy, such as chatbots and intelligent agents. This approach promises improved multi-step agent workflows, preventing loops and enhancing planning, reasoning, and self-correction.

Budget Reasoning Models Outperform Giants: Conquering Logic Puzzles with Reinforcement Learning

2025-03-06

Researchers used reinforcement learning to train smaller, cheaper open-source language models that surpassed DeepSeek R1, OpenAI's o1 and o3-mini, and nearly matched Anthropic's Sonnet 3.7 in a reasoning-heavy game called "Temporal Clue," while being over 100x cheaper at inference time. They achieved this through careful task design, hyperparameter tuning, and the use of the Group Relative Policy Optimization (GRPO) algorithm and the torchtune library. This research demonstrates the potential of reinforcement learning to efficiently train open models for complex deduction tasks, even with limited data, achieving significant performance gains with as few as 16 training examples.

AGI Arms Race: Avoiding Mutual Assured AI Malfunction (MAIM)

2025-03-06

A policy paper by Eric Schmidt, Alexandr Wang, and Dan Hendrycks warns against a "Manhattan Project" style push for Artificial General Intelligence (AGI), arguing that a US-led race for superintelligent AI could provoke fierce retaliation from China, potentially destabilizing international relations. They introduce the concept of Mutual Assured AI Malfunction (MAIM) and suggest a defensive strategy prioritizing deterring other countries from creating threatening AI. This involves expanding cyberattack capabilities, limiting adversaries' access to advanced AI chips and open-source models, rather than focusing on "winning the race to superintelligence." This contrasts with recent proposals for government-backed AGI development and marks a shift in Schmidt's previously expressed views.

SepLLM: Inference Acceleration for LLMs by Compressing Meaningless Tokens

2025-03-06

Large Language Models (LLMs) face significant challenges due to their massive computational demands. Researchers discovered that certain meaningless special tokens contribute disproportionately to attention scores. Based on this, they propose SepLLM, a framework that accelerates inference by compressing segments between these tokens and dropping redundant ones. Experiments show SepLLM achieves over 50% reduction in KV cache on the GSM8K-CoT benchmark with negligible performance loss using Llama-3-8B. In streaming settings, SepLLM effectively handles language modeling with up to 4 million tokens or more.
