Large Language Model

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…

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…

Large Language Models (LLMs) have become pivotal in natural language processing (NLP), excelling in tasks such as text generation, translation, sentiment analysis, and question-answering. The ability to fine-tune these models for various applications is key, allowing practitioners to use the pre-trained knowledge of the LLM while needing fewer labeled data and computational resources than starting…

Large language models (LLMs) have revolutionized the field of natural language processing due to their ability to absorb and process vast amounts of data. However, they have one significant limitation represented by the 'Reversal Curse', the problem of comprehending logical reversibility. This refers to their struggle in understanding that if A has a feature B,…

Apple researchers are implementing cutting-edge technology to enhance interactions with virtual assistants. The current challenge lies in accurately recognizing when a command is intended for the device amongst background noise and speech. To address this, Apple is introducing a revolutionary multimodal approach. This method leverages a large language model (LLM) to combine diverse types of data,…

In the world of computational models for visual data processing, there remains a consistent pursuit for models that merge efficiency with the capability to manage large-scale, high-resolution datasets. Traditional models have often grappled with scalability and computational efficiency, particularly when used for high-resolution image and video generation. Much of this challenge arises from the quadratic…

"Text mining" refers to the discovery of new patterns and insights within large amounts of textual data. Two essential activities in text mining are the creation of a taxonomy - a collection of structured, canonical labels that characterize features of a corpus - and text classification, which assigns labels to instances within the corpus according…
