This release follows the previous release of the Gemma 2 series. It includes various new tools to enhance these models’ application and functionality in diverse technological and research environments. The Gemma 2 2B model…
Time series data, representing observations recorded sequentially over time, permeate various aspects of nature and business, from weather patterns and heartbeats to stock prices and production metrics. Efficiently processing and forecasting these data series can offer significant advantages, such as strategic business planning and anomaly detection in complex systems. However, despite the numerous models and…
The quick development of Large Language Models (LLMs) has had a big impact on a number of different domains, like generative AI, Natural Language Understanding, and Natural Language Processing. However, hardware limitations have historically made running these models locally on a laptop, desktop, or mobile device difficult. To overcome this issue, the PyTorch team has…
Direct Preference Optimization (DPO) is an advanced training method to fine-tune large language models (LLMs). Unlike traditional supervised fine-tuning, which depends on a single gold reference, DPO trains models to differentiate between the quality of various candidate outputs. This technique is crucial for aligning LLMs with human preferences, enhancing their ability to generate desired responses…
Early work established polynomial-time algorithms for finding the densest subgraph, followed by explorations of size-constrained variants and extensions to multiple graph snapshots. Researchers have also investigated overlapping dense subgraphs and alternative density measures. Various algorithmic approaches, including greedy and iterative methods, have been developed to address these challenges. The paper builds on this foundation by…
In AI, developing language models that can efficiently and accurately perform diverse tasks while ensuring user privacy and ethical considerations is a significant challenge. These models must handle various data types and applications without compromising performance or security. Ensuring that these models operate within ethical frameworks and maintain user trust adds another layer of complexity…
Meta has introduced SAM 2, the next generation of its Segment Anything Model. Building on the success of its predecessor, SAM 2 is a groundbreaking unified model designed for real-time promptable object segmentation in images and videos.
