Natural language processing has been making significant headway recently, with a special focus on fine-tuning large language models (LLMs) for specified tasks. These models typically comprise billions of parameters, hence customization can be a challenge. The goal is to devise more efficient methods that customize these models to particular downstream tasks without overwhelming computational costs.…
The rapid evolution of natural language processing (NLP) is currently focused on refining large language models (LLMs) for specific tasks, which often contain billions of parameters posing a significant challenge for customization. The primary goal is to devise better methods to fine-tune these models to particular downstream tasks with minimal computational costs, posing a need…
AI models like ChatGPT and GPT-4 have made significant strides in different sectors, including healthcare. Despite their success, these Large Language Models (LLMs) are vulnerable to malicious manipulation, leading to harmful outcomes, especially in contexts with high stakes like healthcare.
Past research has evaluated the susceptibility of LLMs in general sectors; however, manipulation on such models…
Model selection is a critical part of addressing real-world data science problems. Traditionally, tree ensemble models such as XGBoost have been favored for tabular data analysis. However, deep learning models have been gaining traction, purporting to offer superior performance on certain tabular datasets. Recognising the potential inconsistency in benchmarking and evaluation methods, a team of…
Research out of Princeton University makes a critical commentary on the current practice of evaluating artificial intelligence (AI) agents predominantly based on accuracy. The researchers argue that this unidimensional evaluation method leads to unnecessarily complex and costly AI agent architectures, which can hinder practical implementations.
The evaluation paradigms for AI agents have traditionally focused on…
Function-calling agent models are a critical advancement in large language models (LLMs). They interpret natural language instructions to execute API calls, facilitating real-time interactions with digital services, like retrieving market data or managing social media interactions. However, these models often face challenges as they require high-quality, diverse and verifiable datasets. Unfortunately, many existing datasets lack…
Language modeling in the area of artificial intelligence is geared towards creating systems capable of understanding, interpreting, and generating human language. With its myriad applications, including machine translation, text summarization, and creation of conversational agents, the goal is to develop models that mimic human language abilities, thereby fostering seamless interaction between humans and machines. This…
Large language models (LLMs) are becoming progressively more powerful, with recent models exhibiting GPT-4 level performance. Nevertheless, using these models for applications requiring extensive context, such as understanding long-duration videos or coding at repository-scale, presents significant hurdles. Typically, these tasks require input contexts ranging from 100K to 10M tokens — a great leap from the…
Researchers from Stanford University have developed a new model to investigate the contributions of individual data points to machine learning processes. This allows an understanding of how the value of each data point changes as the scale of the dataset grows, illustrating that some points are more useful in smaller datasets, while others become more…
Overfitting is a prevalent problem when training large neural networks on limited data. It indicates a model's strong performance on the training data but its failure to perform comparably on unseen test data. This issue arises when the network’s feature detectors become overly specialized to the training data, building complex dependencies that do not apply…
The computer vision sector is currently dominated by large-scale models that offer remarkable performance but demand high computational resources, making them impractical for real-world applications. To address this, the Google Research Team has opted to reduce these models into smaller, more efficient architectures via model pruning and knowledge distillation. The team's focus is on knowledge…
Self-supervised learning (SSL) has broadened the application of speech technology by minimizing the requirement for labeled data. However, the current models only support approximately 100-150 of the over 7,000 languages in the world. This is primarily due to the lack of transcribed speech and the fact that only about half of these languages have formal…
