Researchers from Columbia University and Databricks Mosaic AI have conducted a comparative study of full finetuning and Low-Rank Adaptation (LoRA), a parameter-efficient finetuning method, in large language models (LLMs). The efficient finetuning of LLMs, which can contain billions of parameters, is an ongoing challenge due to the substantial GPU memory required. This makes the process…
Recent research suggests that incorporating demonstrating examples, or in-context learning (ICL), significantly enhances large language models' (LLM's) and large multimodal models' (LMM's) performance. Studies have shown improvements in LLM performance with increased in-context examples, particularly in out-of-domain tasks. These findings are driven by newer models such as GPT-4o and Gemini 1.5 Pro, which include longer…
Data mapping, which involves linking fields from one database to another, is a crucial part of data management, particularly in transforming and integrating data from varying sources into a cohesive format. An innovative perspective on this process frames it as a search problem. The efficacy of viewing data mapping as a search problem provides useful…
Machine learning (ML) has become a fundamental part of several industries worldwide due to its wide range of applications. However, understanding and interpreting complex ML models continues to be a challenge. These models, often comprising multiple layers and intricate connections, require precise graph visualization tools to understand how data travels across the model and how…
Machine Learning (ML) models are increasingly becoming an integral part of various sectors globally, with their extensive applications and growing reliance on their capabilities.

The world of Artificial Intelligence (AI) has taken another step forward with the introduction of the recent Yi-1.5-34B model by 01.AI. This model is considered a significant upgrade over prior versions, providing a bridge between the capabilities of the Llama 3 8B and the 70B models.
The distinguishing features of the Yi-1.5-34B include improvements in multimodal…
Large language models (LLMs) have been successful in areas like natural language tasks and following instructions, yet they have limitations when dealing with non-textual data such as images and audio. But presently, an approach integrating textual LLMs with speech encoders in one training setup could revolutionize this. One option is multimodal audio-language models, proving advantageous…
The standard method for aligning Language Learning Models (LLMs) is known as RLHF, or Reinforcement Learning from Human Feedback. However, new developments in offline alignment methods - such as Direct Preference Optimization (DPO) - challenge RLHF's reliance on on-policy sampling. Unlike online methods, offline algorithms use existing datasets, making them simpler, cheaper, and often more…
Natural Language Processing (NLP) is a revolutionary field that allows machines to understand, interpret, and generate human language. It is widely used in various sectors, including language translation, text summarization, sentiment analysis, and the creation of conversational agents. Large language models (LLMs), which have greatly improved these applications, require huge computational and energy demands for…
Recent multimodal foundation models are often limited in their ability to fuse various modalities, as they typically utilize distinct encoders or decoders for each modality. This structure limits their capability to effectively integrate varied content types and create multimodal documents with interwoven sequences of images and text.
Meta researchers, in response to this limitation, have…
Artificial Intelligence (AI) systems have demonstrated a fascinating trend of converging data representations across different architectures, training objectives, and modalities. Researchers propose the "Platonic Representation Hypothesis" to explain this phenomenon. Essentially, this hypothesizes that various AI models are striving to capture a unified representation of the underlying reality that forms the basis for observable data.…
