👉 What is Trending in AI/ML Research?

Despite the massive interest in Large Language Models LLMs over the last year, many enterprises are still struggling to realize the full potential of generative AI due to challenges in integrating LLMs into existing enterprise workflows. As LLMs have exploded on the scene, with huge leaps and bounds in model technologies over the last year, development tools have been playing catch up, and to date, there is still a big gap in enterprise-ready unified, open development frameworks to build enterprise LLM-based applications rapidly and at scale. In the absence of a unified development framework, most enterprise development teams have been trying to stitch together various custom tools, open source, different vendor solutions, and multiple different libraries in an attempt to build new custom data pipelines and processes for LLMs, slowing adoption and time-to-value.

Recognizing this need, as a provider of enterprise LLM-based applications in the financial services and legal industries, Ai Bloks has released its development framework in a new open-source library that it is branding LLMWare. According to Ai Bloks CEO Darren Oberst, “As we talked with clients and partners over the last year, we saw most businesses struggling to figure out a common pattern for retrieval augmented generation (RAG), bringing together LLMs with embedding models, vector databases, text search, document parsing and chunking, fact-checking and post-processing, and to address this need, we have launched LLMWare as an open source project to build a community around this framework and democratize RAG best practices and related enterprise LLM patterns.”

How effective are language models in resolving real-world software engineering problems? To tackle this question, this paper presents "SWE-bench", an evaluation framework constructed from 2,294 genuine GitHub issues and pull requests from 12 top Python repositories. In this challenging testbed, a language model is assigned to edit codebases based on issue descriptions. Addressing these issues often demands multifaceted reasoning, spanning multiple classes, functions, and files. Preliminary assessments reveal that even advanced models like Claude 2 and GPT-4 solve only 4.8% and 1.7% of the problems, respectively. Progress on SWE-bench indicates strides towards more practical and intelligent language models.

How can we overcome the computational challenges arising from long contexts in Large Language Models? This paper introduces "HyperAttention", an innovative approximate attention mechanism tailored for LLMs. While conventional wisdom necessitates quadratic time for certain scenarios, HyperAttention bypasses this with two new parameters that gauge matrix norms, permitting a linear time sampling algorithm under specific conditions. Notably, HyperAttention integrates seamlessly with fast implementations like FlashAttention. Empirical tests, utilizing Locality Sensitive Hashing (LSH) to pinpoint large entries, reveal HyperAttention's superior speed over contemporaneous methods. For instance, with HyperAttention, ChatGLM2's inference time drops by half on 32k context length, showcasing its computational efficiency.

Can non-invasive brain recordings be decoded to represent seen visual content in natural language? Addressing this challenge, the paper presents "MindGPT", a novel neural decoder that translates perceived visual stimuli from fMRI signals into descriptive language. Rather than attempting to reconstruct images pixel-by-pixel, MindGPT uses a visually guided neural encoder with a cross-attention mechanism, leveraging the vast knowledge of the GPT language model. This allows the transformation of neural representations into semantically coherent language in an end-to-end process. The study found that MindGPT's outputs are semantically rich and align closely with visual stimuli. Furthermore, the higher visual cortex (HVC) was identified as more semantically informative than the lower visual cortex (LVC).

How can we improve the accuracy of machine learning models predicting semantic information about user interfaces (UIs) without relying heavily on human-labeled data? This paper introduces the "Never-ending UI Learner", an automated app crawler designed to sidestep the limitations of human annotators. Instead of relying on static screenshots, this crawler autonomously installs and navigates real apps from app stores. It interacts with UI elements directly, learning their semantic properties from real-time feedback, thereby continually updating and refining the underlying machine learning models. The system has logged over 5,000 device-hours, engaging with 6,000 apps to bolster three computer vision models, particularly focusing on predicting 'tappability'.
