The evaluation of Large Language Models (LLMs) requires a systematic and multi-layered approach to accurately identify areas of improvement and limitations. As these models advance and become more intricate, their assessment presents greater challenges due to the diversity of tasks they are required to execute. Current benchmarks often employ non-precise, simplistic criteria such as "helpfulness"…
The Allen Institute for AI has recently launched the Tulu 2.5 suite, a revolutionary progression in model training employing Direct Preference Optimization (DPO) and Proximal Policy Optimization (PPO). The suite encompasses an array of models that have been trained on several datasets to augment their reward and value models, with the goal of significantly enhancing…
DeepMind researchers have presented TransNAR, a new hybrid architecture which pairs the language comprehension capabilities of Transformers with the robust algorithmic abilities of pre-trained graph neural networks (GNNs), known as neural algorithmic reasoners (NARs. This combination is designed to enhance the reasoning capabilities of language models, while maintaining generalization capacities.
The routine issue faced by…
With their capacity to process and generate human-like text, Large Language Models (LLMs) have become critical tools that empower a variety of applications, from chatbots and data analysis to other advanced AI applications. The success of LLMs relies heavily on the diversity and quality of instructional data used for training.
One of the operative challenges in…
Large Language Models (LLMs) are crucial for a variety of applications, from machine translation to predictive text completion. They face challenges, including capturing complex, long-term dependencies and enabling efficient large-scale parallelisation. Attention-based models that have dominated LLM architectures struggle with computational complexity and extrapolating to longer sequences. Meanwhile, State Space Models (SSMs) offer linear computation…
Pre-trained Large language models (LLMs), such as transformers, typically have a fixed context window size, most commonly around 4K tokens. Nevertheless, numerous applications require processing significantly longer contexts, going all the way up to 256K tokens. The challenge that arises in elongating the context length of these models lies primarily in the efficient use of…
The proliferation of Large Language Models (LLMs) in the field of Artificial Intelligence (AI) has been a topic of much debate on Reddit. In a post, a user highlighted the existence of over 700,000 LLMs, raising questions about the usefulness and potential of these models. This has sparked a broad debate about the consequences of…
The Galileo Luna is a transformative tool in the evaluation of language model processes, specifically addressing the prevalence of hallucinations in large language models (LLMs). Hallucinations refer to situations where models generate information that isn’t specific to a retrieved context, a significant challenge when deploying language models in industry applications. Galileo Luna combats this issue…
Large language models (LLMs), such as those used in AI, can creatively solve complex tasks in ever-changing environments without the need for task-specific training. However, achieving broad, high-level goals with these models remain a challenge due to the objectives' ambiguous nature and delayed rewards. Frequently retraining models to fit new goals and tasks is also…
A team from Stanford and Duolingo has proposed a new way to manage the proficiency level in texts generated by large language models (LLMs), overcoming limitations in current methods. The Common European Framework of Reference for Languages (CEFR)-aligned language model (CALM) combines techniques of finetuning and proximal policy optimization (PPO) for aligning the proficiency levels…
