Artificial intelligence possesses large language models (LLMs) like GPT-4 that enable autonomous agents to carry out complex tasks within various environments with unprecedented accuracy. However, these agents still struggle to learn from failures, which is where the Exploration-based Trajectory Optimization (ETO) method comes in. This training introduced by the Allen Institute for AI; Peking University's…
The rise of diffusion models in the field of machine learning is making significant strides in modeling complex data distributions and generating realistic samples from various domains, such as images, videos, audio, and 3D scenes. Nevertheless, full theoretical comprehension of generative diffusion models continues to be a challenging frontier requiring a more elaborate understanding, particularly…
If you've had experience programming in languages such as C++ or Java, you are probably familiar with enums (enumerations), utilised to create name constants. These are particularly useful when you have a variable that is expected to take one of a predefined set of values, e.g., days of the week or student grades. While Python…
Causal AI is the insertion of causal reasoning into machine learning. Causal graphs, known as directed acyclic graphs (DAGs), help to differentiate causes and correlations and are essential for the causal inference toolbox in causal AI. They can establish causal relationships and account for situations that machine learning cannot, such as spurious correlations, confounders, mediators,…
Machine learning advancements, especially in designing neural networks, have made significant progress thanks to Neural Architecture Search (NAS), a technique that automates the architectural design process. By eliminating the need for manual intervention, NAS not only simplifies a previously tedious process, but also paves the way for the development of more effective and accurate models,…

Despite remarkable advances in large language models (LLMs) like ChatGPT, Llama2, Vicuna, and Gemini, these platforms often struggle with safety issues. These problems often manifest as the generation of harmful, incorrect, or biased content by these models. The focus of this paper is on a new safety-conscious decoding method, SafeDecoding, that seeks to shield LLMs…
The field of large language models (LLMs) has witnessed significant advances thanks to the introduction of State Space Models (SSMs). Offering a lower computational footprint, SSMs are seen as a welcome alternative. The recent development of DenseSSM represents a significant milestone in this regard. Designed by a team of researchers at Huawei's Noah's Ark Lab,…
The rapid development in Large Language Models (LLMs) has seen billion- or trillion-parameter models achieve impressive performance across multiple fields. However, their sheer scale poses real issues for deployment due to severe hardware requirements. The focus of current research has been on scaling models to improve performance, following established scaling laws. This, however, emphasizes the…
Large Language Models (LLMs) such as GPT-4 and Llama-2, while highly capable, require fine-tuning with specific data tailored to various business requirements. This process can expose the models to safety threats, most notably the Fine-tuning based Jailbreak Attack (FJAttack). The introduction of even a small number of harmful examples during the fine-tuning phase can drastically…
The application of machine learning, particularly generative models, has lately become more prominent due to the advent of diffusion models (DMs). These models have proved instrumental in modeling complex data distributions and generating realistic samples in numerous areas, including image, video, audio, and 3D scenes. Despite their practical benefits, there are gaps in the full…
