CODE-GEN: A Human-in-the-Loop RAG-Based Agentic AI System for Multiple-Choice Question Generation

Researchers developed CODE-GEN, a human-in-the-loop AI system that uses retrieval-augmented generation to create multiple-choice programming questions for educational purposes. The system achieved 79.9% to 98.6% success rates across seven pedagogical dimensions when evaluated by subject-matter experts, demonstrating strong performance in computational verification tasks while still requiring human expertise for complex instructional design.

A Model of Understanding in Deep Learning Systems

A new research paper proposes a model for understanding in deep learning systems, arguing that contemporary AI can achieve systematic understanding through internal models that track regularities and support reliable predictions. However, the research suggests this understanding falls short of scientific ideals due to symbolic misalignment and lack of explicit reductive properties.

Same World, Differently Given: History-Dependent Perceptual Reorganization in Artificial Agents

Researchers developed a minimal AI architecture where a 'perspective latent' creates history-dependent perception in artificial agents. The system allows identical observations to be processed differently based on accumulated experience, demonstrating measurable plasticity that persists even after conditions return to normal.

Fusion and Alignment Enhancement with Large Language Models for Tail-item Sequential Recommendation

Researchers propose FAERec, a new framework that uses large language models to improve sequential recommendation systems for rarely-interacted (tail) items. The system addresses fusion and alignment challenges between collaborative signals and semantic knowledge to enhance recommendation accuracy.

Gram-Anchored Prompt Learning for Vision-Language Models via Second-Order Statistics

Researchers propose Gram-Anchored Prompt Learning (GAPL), a new framework that improves Vision-Language Model adaptation by incorporating second-order statistical features via Gram matrices. This approach enhances robustness against domain shifts and local noise compared to existing methods that rely solely on first-order spatial features.

Discrete Prototypical Memories for Federated Time Series Foundation Models

Researchers propose FeDPM, a federated learning framework that addresses semantic misalignment issues when using Large Language Models for time series analysis.
