RedOne 2.0: Revolutionizing Social Media AI with Domain-Specific LLM Training
2 months ago 高效码农RedOne 2.0: Rethinking Domain-Specific LLM Post-Training for Social Networking Services Introduction: Why Social Networking Services Need Specialized Large Language Models? Core Question This Section Aims to Answer: What unique challenges do general-purpose large language models face when deployed in social networking services? General-purpose LLMs frequently underperform in social networking environments due to rapidly evolving trends, diverse cultural contexts, and heterogeneous workloads. Social platforms contain constantly changing content: new memes emerge overnight, community norms shift daily, and users communicate in multiple languages across different cultural backgrounds. These factors cause general models to misinterpret community-specific rules, over-enforce or under-enforce policies, and experience …
SofT-GRPO: How Gumbel-Softmax Revolutionizes LLM Reinforcement Learning
2 months ago 高效码农SofT-GRPO: Revolutionizing LLM Reinforcement Learning with Soft-Thinking Policy Optimization Core Question Answered This article explains how SofT-GRPO solves the fundamental challenge of applying reinforcement learning to soft-thinking LLMs, achieving superior performance over discrete-token methods through innovative Gumbel noise injection and reparameterization techniques. Introduction: The Bottleneck of Traditional Discrete-Token Reasoning Large language models have transformed reasoning capabilities across diverse domains, yet most existing methods remain constrained by discrete token selection.

Autoregression vs Diffusion Models: The Future of AI Content Generation
2 months ago 高效码农Exploring Powerful Ways to Generate: Autoregression, Diffusion, and Beyond Have you ever wondered how AI models like those behind chatbots or code generators create new content? It’s not magic—it’s all about the generation process, the step-by-step method the model uses to build sequences like sentences, puzzles, or even graphs. Traditional approaches, like predicting the next word one at a time, work well for everyday language but can stumble on tougher tasks, such as solving complex puzzles or designing molecular structures. A recent paper dives deep into this, comparing classic autoregressive models with newer masked diffusion techniques and proposing an enhanced …
QueStER: A Revolutionary Approach to Information Retrieval Using Small Language Models
2 months ago 高效码农Introduction: The Challenge of Modern Information Retrieval In today’s digital landscape, finding relevant information efficiently has become increasingly complex. Traditional search engines face a fundamental challenge known as the “vocabulary mismatch problem” – where user queries contain keywords that don’t appear in relevant documents. This gap between what users search for and what documents contain leads to frustrating search experiences and missed information. Information Retrieval (IR) systems serve as the backbone of search engines and Retrieval-Augmented Generation (RAG) models. For decades, bag-of-words models like BM25 have dominated the field due to their speed and efficiency. These systems rely on term-specific …
Continuous Autoregressive Language Models: Revolutionizing LLM Training and Text Generation Efficiency
3 months ago 高效码农“ A plain-language tour of “Continuous Autoregressive Language Models” (arXiv 2510.27688) for junior-college-level readers who want cleaner training bills and faster text generation—without chasing hype. 1. Why another language-model paper matters Large Language Models (LLMs) write like angels but burn cash like heaters. The root cause is no secret: they produce text token by token. Every new word means another forward pass through billions of parameters and an attention matrix that grows quadratically. Long prompt? Long bill. CALM (Continuous Autoregressive Language Models) attacks the length problem instead of the width problem. Rather than predicting the next word piece, it predicts …
Revolutionizing Semantic RAG: The Power of Knowledge Graph Traversal Algorithms
3 months ago 高效码农Novel Knowledge Graph Traversal Algorithms: Enhancing Accuracy in Semantic Retrieval-Augmented Generation (RAG) Systems In the fast-paced evolution of artificial intelligence, large language models (LLMs) have become indispensable tools for information processing. However, relying solely on an LLM’s internal knowledge often limits its ability to answer complex or domain-specific questions accurately. This is where Retrieval-Augmented Generation (RAG) systems shine—they supplement LLMs with context from databases or knowledge graphs, enabling more precise and well-grounded responses. Yet traditional RAG systems have a critical limitation: they mostly rely on text matching in vector stores, which struggles to capture deep semantic connections between pieces of …
