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…
Stanford University is renowned for its contributions to artificial intelligence research and advancements, offering numerous courses equipped with practical knowledge for its students. Various AI aspects are covered, including machine learning, deep learning, natural language processing, and other crucial AI technologies. The courses are revered for their depth, relevance, and rigor making them paramount for…
In recent years, comparisons have been made between protein sequences and natural language due to their sequential structures, facilitating notable progress in deep learning models in both areas. Large language models (LLMs), for example, have seen significant success in natural language processing (NLP) tasks, prompting attempts to adapt them to interpret protein sequences.
However, these efforts…
ChatGPT, which is possibly the most popular AI chatbot worldwide, was down recently, causing a wave of panic amongst enthusiasts who started fervently searching for alternatives. The reason for the outage was not disclosed by OpenAI, but it is back up and running now. With this incident, focus has been drawn to an issue many…
Detecting personally identifiable information (PII) in documents can be a complex task due to numerous regulations like the EU's GDPR and multiple U.S. data protection laws. A flexible approach is needed given the variations in data formats and domain-specific requirements. In response, Gretel has developed a synthetic dataset to help with PII detection.
Gretel's Navigator tool…
Transformer-based generative Large Language Models (LLMs) are showing significant strength in various Natural Language Processing (NLP) tasks. Among those benefiting are application developers, who interact with LLMs through APIs supplied by AI firms such as Google, OpenAI, and Baidu, who provide language model-as-a-service (LMaaS) platforms.
In the LMaaS scenario, developers send the LLM service user input…
Luma Labs recently unveiled Dream Machine, an advanced AI model built to generate high-quality, realistic, and fantasy videos from text and images. This AI device, which is built on a scalable, multimodal transformer architecture, is a significant step forward in AI technology. It has been specifically designed for video creation and is trained directly on…
