General Intelligence Requires Reward-based Pretraining

Best AI papers explained ·

2025/06/25

This position paper argues that Large Language Models (LLMs), despite their current utility as Artificial Useful Intelligence (AUI), often struggle with robust and adaptive reasoning required for Artificial General Intelligence (AGI) because their training methods overfit to specific data patterns. The authors propose a shift from the current supervised pretraining (SPT) paradigm to reward-based pretraining (RPT), similar to how AlphaZero surpassed AlphaGo by learning purely through reinforcement

Best AI papers explained ·

2025/06/25

This position paper argues that probabilistic modeling is sufficient for causal inference, directly challenging the prevalent idea that specialized causal frameworks or notation, such as Pearl's "do-operator," are necessary. The authors demonstrate through concrete examples like aspirin's effect on headaches how interventional and counterfactual questions can be answered by explicitly defining joint probability distributions across observed and hypothetical "intervened" or "counterfactual" worlds

Not All Explanations for Deep Learning Phenomena Are...

Best AI papers explained ·

2025/06/25

This academic paper argues that not all explanations for deep learning phenomena hold equal value, particularly those observed in "edge cases" like double descent, grokking, and the lottery ticket hypothesis. The authors contend that focusing on narrow, ad hoc explanations for isolated phenomena is often inefficient and lacks practical utility in real-world applications. Instead, they advocate for a more pragmatic and scientific approach, urging researchers to leverage these phenomena as test beds

Best AI papers explained ·

2025/06/17

The provided text introduces "e3," a new training methodology for Large Language Models (LLMs) designed to improve their reasoning capabilities and enable extrapolation of test-time compute. This means LLMs can continue to enhance performance even when given more processing time than they were trained on. The core of e3 lies in three key components: leveraging asymmetries in LLM competence, where models are better at verifying answers than generating them; utilizing negative gradients in

Best AI papers explained ·

2025/06/17

This academic paper explores length generalization transfer in Transformer language models, investigating their ability to extrapolate knowledge from shorter inputs to longer, unseen ones. The authors demonstrate that training a model on a related "auxiliary task" with longer inputs can significantly improve the generalization of a "main task" trained only on shorter examples, across diverse domains like arithmetic, string manipulation, and maze navigation. This transfer effect

Best AI papers explained ·

2025/06/17

This paper investigates the underlying capabilities of large language models (LMs) by analyzing their performance on various benchmarks. The authors propose a novel Hierarchical Component Analysis (HCA) algorithm to uncover latent hierarchical structures within these capabilities. Through Principal Component Analysis (PCA), the study identifies that benchmark performance data exhibits an approximate low-rank structure, suggesting a limited number of core abilities. Furthermore, the research

Generalization or Hallucination? Understanding...

Best AI papers explained ·

2025/06/17

This academic paper explores why large language models (LLMs) both generalize correctly and "hallucinate" incorrect information when fine-tuned with new facts. The authors propose that out-of-context reasoning (OCR) is the single underlying mechanism responsible for both phenomena. They demonstrate through experiments on five prominent LLMs that OCR drives generalization when concepts are causally related and hallucination when they are not. Furthermore, the research formalizes OCR as a

Best AI papers explained ·

2025/06/17

The academic paper introduces GATE (Generative Augmentation for Treatment Effect estimation), a novel framework designed to improve the estimation of Conditional Average Treatment Effects (CATE), particularly when working with limited observational data. The core concept involves data augmentation, where synthetic counterfactual outcomes are generated using pre-trained generative models, specifically Large Language Models (LLMs). This augmentation strategy aims to address critical challenges in CATE

Self-Adapting Language Models

Best AI papers explained ·

2025/06/17

This paper introduces Self-Adapting LLMs (SEAL), a novel framework enabling large language models to autonomously enhance their capabilities by generating and utilizing their own training data. Unlike static models, SEAL employs a reinforcement learning loop where the model produces "self-edits"—instructions for finetuning data and optimization—and is rewarded based on the performance of the updated model. Experiments demonstrate SEAL's effectiveness in knowledge

Best AI papers explained ·

2025/06/17

This paper investigates In-Context Learning (ICL) models, particularly those employing transformers, from a learning-to-learn perspective. The authors theoretically demonstrate that ICL models are expressive enough to emulate existing meta-learning algorithms, such as gradient-based, metric-based, and amortization-based approaches. Their findings suggest that ICL learns data-dependent optimal algorithms during pre-training, which, while powerful, can limit generalizability to out-of-distribution or

Causal Attribution Analysis for Continuous Outcomes

Best AI papers explained ·

2025/06/12

This paper introduces a novel approach to causal attribution analysis for continuous outcome variables, a significant departure from prior research primarily focused on binary outcomes. This new method proposes a series of posterior causal estimands, such as posterior intervention effects, posterior total causal effects, and posterior natural direct effects, to retrospectively evaluate multiple correlated causes of a continuous effect. The authors establish the identifiability of these estimands

Best AI papers explained ·

2025/06/12

This academic paper explores the emergence and transience of in-context learning (ICL) in transformer models, revealing a dynamic interplay with another strategy, context-constrained in-weights learning (CIWL). The authors term this phenomenon "strategy coopetition," where ICL and CIWL both cooperate by sharing underlying neural circuits and compete for dominance during training. While ICL appears earlier, it is ultimately superseded by CIWL, yet its initial emergence is facilitated by the
