1ļøāƒ£ Meet RAVEN: A Retrieval-Augmented Encoder-Decoder Language Model That Addresses The Limitations Of ATLASĀ [Paper] [Blog]

This paper explores the in-context learning capabilities of retrieval-augmented encoder-decoder language models, specifically scrutinizing the ATLAS model's limitations, such as the mismatch between pretraining and testing phases and restricted context length. To tackle these issues, the authors introduce RAVEN, a novel model that combines retrieval-augmented masked language modeling with prefix language modeling. They also unveil Fusion-in-Context Learning, a method that boosts few-shot learning performance by allowing the model to effectively use more in-context examples without additional training or adjustments. Through extensive testing, RAVEN is shown to substantially outperform ATLAS and rival the performance of more advanced models, despite having fewer parameters. The study suggests that retrieval-augmented models hold significant promise for in-context learning, encouraging further research in the area.

2ļøāƒ£ Researchers from Cornell Introduce Quantization with Incoherence Processing (QuIP): A New AI Method based on the Insight that Quantization Benefits from Incoherent Weight and Hessian MatricesĀ [Blog] [Paper]

This paper explores the topic of post-training parameter quantization in large language models (LLMs). The authors introduce a novel method called Quantization with Incoherence Processing (QuIP), designed to optimize the quantization process by leveraging incoherent weight and Hessian matrices. QuIP involves two main steps: adaptive rounding that minimizes a quadratic proxy objective and a pre- and post-processing routine that ensures matrix incoherence through multiplication by random orthogonal matrices. The paper also presents the first theoretical analysis for quantization at the scale of LLMs. Importantly, it demonstrates that QuIP not only improves upon existing quantization algorithms but also makes it possible to produce practical results using just two bits per weight, thereby improving efficiency.

3ļøāƒ£ Meer Pyrus Base: A New Open-Source Python-Based Platform for the Two-Dimensional (2D) Simulation of RoboCup Soccer [Paper] [Blog]

The paper introduces Pyrus, the first Python-based code for Soccer Simulation 2D (SS2D), part of the annual RoboCup competition. Traditional SS2D games have relied on C++ base codes to control agents and their interactions with the RoboCup Soccer Simulation Server. While effective, these C++ codes present a steep learning curve, particularly for beginners, hindering wider participation. Pyrus aims to overcome this limitation by offering an accessible yet robust Python-based framework. The open-source nature of Pyrus is designed to facilitate easier integration of machine learning algorithms, thereby attracting a broader range of researchers to develop innovative strategies in computer-based soccer simulations.

4ļøāƒ£ Line Open-Sources ā€˜japanese-large-lmā€™: A Japanese Language Model With 3.6 Billion Parameters [Blog]

Since November 2020, LINE has embarked on a transformative journey of research and development to create and harness the power of an advanced large-scale language model tailored specifically for the Japanese language. As a significant milestone in this journey, LINEā€™s Massive LM development unit has announced the release of their Japanese language models, ā€œJapanese-large-lm,ā€ as open-source software (OSS). This release is poised to significantly impact both the research community and businesses seeking to leverage cutting-edge language models.
