Researchers from Google DeepMind have introduced Gecko, a groundbreaking text embedding model to transform text into a form that machines can comprehend and act upon. Gecko is unique in its use of large language models (LLMs) for knowledge distillation. As opposed to conventional models that depend on comprehensive labeled datasets, Gecko initiates its learning journey…
Artificial intelligence and deep learning models, despite their popularity and capacity, often struggle with generalization, particularly when they encounter data that differs from what they were trained on. This issue arises when the distribution of training and testing data varies, resulting in reduced model performance.
The concept of domain generalization has been introduced to combat…
Large Language Models (LLMs) have shown significant impact across various tasks within the software engineering space. Leveraging extensive open-source code datasets and Github-enabled models like CodeLlama, ChatGPT, and Codex, they can generate code and documentation, translate between programming languages, write unit tests, and identify and rectify bugs. AlphaCode is a pre-trained model that can help…
The ability of large Multimodal Language Models (MLLMs) to tackle visual math problems is currently the subject of intense interest. While MLLMs have performed remarkably well in visual scenarios, the extent to which they can fully understand and solve visual math problems remains unclear. To address these challenges, frameworks such as GeoQA and MathVista have…
The increased adoption and integration of large Language Models (LLMs) in the biomedical sector for interpretation, summary and decision-making support has led to the development of an innovative reliability assessment framework known as Reliability AssessMent for Biomedical LLM Assistants (RAmBLA). This research, led by Imperial College London and GSK.ai, puts a spotlight on the critical…
As the advancements in Large Language Models (LLMs) such as ChatGPT, LLaMA, and Mistral continue, there are growing concerns about their vulnerability to harmful queries. This has caused an immediate need to implement robust safeguards. Techniques such as supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), and direct preference optimization (DPO) have been useful…
Generative Language Models (GLMs) are now ubiquitous in various sectors, including customer service and content creation. Consequently, handling potential harmful content while keeping linguistic diversity and inclusivity has become important. Toxicity scoring systems aim to filter offensive or hurtful language, but often misidentify harmless language as harmful, especially from marginalized communities. This restricts access to…
Optimizing efficiency in complex systems is a significant challenge for researchers, particularly in high-dimensional spaces commonly found in machine learning. Second-order methods like the cubic regularized Newton (CRN) method demonstrate rapid convergence; however, their application in high-dimensional problems has been limited due to substantial memory and computational requirements.
To counter these challenges, scientists from UT…
In recent years, natural language processing (NLP) has seen significant advancements due to the transformer architecture. However, as these models grow in size, so do their computational costs and memory requirements, limiting their practical use to a select few corporations. Increasing model depths also present challenges, as deeper models need larger datasets for training, which…
Transformer architecture has greatly enhanced natural language processing (NLP); however, issues such as increased computational cost and memory usage have limited their utility, especially for larger models. Researchers from the University of Geneva and École polytechnique fédérale de Lausanne (EPFL) have addressed this challenge by developing DenseFormer, a modification to the standard transformer architecture, which…
