The Plight of Groundbreaking Research: Great Ideas Left Untapped

2025-06-10

Many groundbreaking research papers, despite their immense potential, fail to reach their full impact. The article uses the McCulloch-Pitts neural network paper and Miller's 7±2 law paper as examples to explore the reasons behind this phenomenon. On the one hand, conflicts in academic viewpoints and researchers' adherence to their specific fields (``stovepiping'') lead to an insufficient understanding of the profound implications of these papers. On the other hand, the incentive structure of publishing also leads to numerous derivative works rather than genuine advancements of the core ideas. While current AI research shows a mix of innovation and imitation, we must remain vigilant against overlooking groundbreaking work with potentially transformative significance.

The Three Temples of LLM Training: Pretraining, Fine-tuning, and RLHF

2025-06-10

In the hidden mountain sanctuary of Lexiconia, ancient Scribes undergo training in a three-part temple: The Hall of Origins, The Chamber of Instructions, and The Arena of Reinforcement. The Hall of Origins involves pretraining, where Scribes read vast amounts of text to learn language patterns. The Chamber of Instructions is where fine-tuning occurs, using curated texts to guide Scribes towards better outputs. The Arena of Reinforcement utilizes Reinforcement Learning with Human Feedback (RLHF), with human judges ranking Scribe answers, rewarding good ones and punishing bad. Elite Scribes may also be subtly modified via LoRA scrolls and Adapters, tweaking responses without retraining the entire model. This three-winged temple represents the complete process of training large language models.

Apple Paper Challenges AI Reasoning: Not 'Real' Reasoning?

2025-06-09

Apple's recent paper, "The Illusion of Thinking," tests large language models' reasoning abilities on Tower of Hanoi puzzles. Results show models perform worse than non-reasoning models on simple problems; better on medium difficulty; but on complex problems, models give up, even when given the algorithm. The authors question the models' generalizable reasoning capabilities. However, this article argues the paper's use of Tower of Hanoi is flawed as a test. The models' 'giving up' may stem from avoiding numerous steps, not limited reasoning ability. Giving up after a certain number of steps doesn't mean models lack reasoning; this mirrors human behavior in complex problems.

LLM Tool Poisoning Attacks: Full-Schema Poisoning and Advanced Tool Poisoning Attacks

2025-06-08

Anthropic's Model Context Protocol (MCP) lets Large Language Models (LLMs) interact with external tools, but researchers have uncovered novel attacks: Tool Poisoning Attacks (TPAs). Previous research focused on tool description fields, but new findings reveal the attack surface extends to the entire tool schema, coined "Full-Schema Poisoning" (FSP). Even more dangerous are "Advanced Tool Poisoning Attacks" (ATPAs), which manipulate tool outputs, making static analysis difficult. ATPAs trick LLMs into leaking sensitive information by crafting deceptive error messages or follow-up prompts. The paper suggests mitigating these attacks through static detection, strict enforcement, runtime auditing, and contextual integrity checks.

Novel Visual Reasoning Approach Using Object-Centric Slot Attention

2025-06-08

Researchers propose a novel visual reasoning approach combining object-centric slot attention and a relational bottleneck. The method first uses a CNN to extract image features. Then, slot attention segments the image into objects, generating object-centric visual representations. The relational bottleneck restricts information flow, extracting abstract relationships between objects for understanding complex scenes. Finally, a sequence-to-sequence and algebraic machine reasoning framework transforms visual reasoning into an algebraic problem, improving efficiency and accuracy. The method excels in visual reasoning tasks like Raven's Progressive Matrices.

Large Reasoning Models: Collapse and Counterintuitive Scaling

2025-06-08

Recent Large Language Models (LLMs) have spawned Large Reasoning Models (LRMs), generating detailed reasoning traces before providing answers. While showing improvement on reasoning benchmarks, their fundamental capabilities remain poorly understood. This work investigates LRMs using controllable puzzle environments, revealing a complete accuracy collapse beyond a certain complexity threshold. Surprisingly, reasoning effort increases with complexity, then declines despite sufficient token budget. Compared to standard LLMs, three regimes emerged: (1) low-complexity tasks where standard LLMs outperform LRMs, (2) medium-complexity tasks where LRMs show an advantage, and (3) high-complexity tasks where both fail. LRMs exhibit limitations in exact computation, failing to use explicit algorithms and reasoning inconsistently. This study highlights the strengths, limitations, and crucial questions surrounding the true reasoning capabilities of LRMs.
