네, 안녕하세요. 반갑습니다. 네, 오늘 바쁜 세상 속에서 트렌드를는 힘 멈춤이라고 하는 주제로다가 여러분들하고 함께 이야기 나누려고 합니다.앞으로 5년 후에 그리고 10년 후에 세상 도대체 어떻게 변하게 될까요. 저도 잘 모르겠습니다. 사실 우리가 5년 후 10년 후에 세상이 어떻게 변하는지 알 수 있으면은 투자를 하시는 분들이라고 한다라면 굉장히 높은 수익률 받으실 수 있을 거고요.만약 여러분들이 사업을 한다라면 절대로 실패하지 않을 거예요. 그런데 저도 IT 트렌드를 10년 넘게 강의하고 있지만은 이런 질문을 받을 때마다 어떻게 될지 짐작도 가지 않을 정도로 요즘 너무 빠르게 세상이 흘러가는 거 같습니다. 오늘 전체 주제가 우리가 흐름이죠.이 이 흐름 속에서 우린 잠깐 멈춰 봐야 될 것 같아요. 자, 제가 확실하게 이야기 드릴 수 있는 거는 먼 미래는 모르지만 저의 오늘은 이야기 드릴 수 있을 것 같아요. 오늘 저는 강의가 끝나고 집에 가면 9시 정도가 될 겁니다.내일도 이야기 드릴 수 있을 것 같 ...
最新综述!扩散语言模型全面盘点~
自动驾驶之心· 2025-08-19 23:32
Core Viewpoint - The article discusses the competition between two major paradigms in generative AI: Diffusion Models and Autoregressive (AR) Models, highlighting the emergence of Diffusion Language Models (DLMs) as a potential breakthrough in the field of large language models [2][3]. Group 1: DLM Advantages Over AR Models - DLMs offer parallel generation capabilities, significantly improving inference speed by achieving a tenfold increase compared to AR models, which are limited by token-level serial processing [11][12]. - DLMs utilize bidirectional context, enhancing language understanding and generation control, allowing for finer adjustments in output characteristics such as sentiment and structure [12][14]. - The iterative denoising mechanism of DLMs allows for corrections during the generation process, reducing the accumulation of early errors, which is a limitation in AR models [13]. - DLMs are naturally suited for multimodal applications, enabling the integration of text and visual data without the need for separate modules, thus enhancing the quality of joint generation tasks [14]. Group 2: Technical Landscape of DLMs - DLMs are categorized into three paradigms: Continuous Space DLMs, Discrete Space DLMs, and Hybrid AR-DLMs, each with distinct advantages and applications [15][20]. - Continuous Space DLMs leverage established diffusion techniques from image models but may suffer from semantic loss during the embedding process [20]. - Discrete Space DLMs operate directly on token levels, maintaining semantic integrity and simplifying the inference process, making them the mainstream approach in large parameter models [21]. - Hybrid AR-DLMs combine the strengths of AR models and DLMs, balancing efficiency and quality for tasks requiring high coherence [22]. Group 3: Training and Inference Optimization - DLMs utilize transfer learning to reduce training costs, with methods such as initializing from AR models or image diffusion models, significantly lowering data requirements [30][31]. - The article outlines three main directions for inference optimization: parallel decoding, masking strategies, and efficiency technologies, all aimed at enhancing speed and quality [35][38]. - Techniques like confidence-aware decoding and dynamic masking are highlighted as key innovations to improve the quality of generated outputs while maintaining high inference speeds [38][39]. Group 4: Multimodal Applications and Industry Impact - DLMs are increasingly applied in multimodal contexts, allowing for unified processing of text and visual data, which enhances capabilities in tasks like visual reasoning and joint content creation [44]. - The article presents various case studies demonstrating DLMs' effectiveness in high-value vertical applications, such as code generation and computational biology, showcasing their potential in real-world scenarios [46]. - DLMs are positioned as a transformative technology in industries, with applications ranging from real-time code generation to complex molecular design, indicating their broad utility [46][47]. Group 5: Challenges and Future Directions - The article identifies key challenges facing DLMs, including the trade-off between parallelism and performance, infrastructure limitations, and scalability issues compared to AR models [49][53]. - Future research directions are proposed, focusing on improving training objectives, building dedicated toolchains, and enhancing long-sequence processing capabilities [54][56].
