Supervised and preference-based fine-tuning techniques have become popular for aligning large language models (LLMs) with user intent and correctness criteria. However, real-world training data often exhibits spurious correlations -- arising from biases, dataset artifacts, or other "shortcut" features -- that can compromise a model's performance or generalization. In this paper, we systematically evaluate three post-training algorithms -- Supervised Fine-Tuning (SFT), Direct Preference Optimization (DPO), and KTO (Kahneman-Tversky Optimization) -- across a diverse set of synthetic tasks and spuriousness conditions. Our tasks span mathematical reasoning, constrained instruction-following, and document-grounded question answering. We vary the degree of spurious correlation (10% vs. 90%) and investigate two forms of artifacts: "Feature Ambiguity" and "Distributional Narrowness." Our results show that the models often but not always degrade under higher spuriousness. The preference-based methods (DPO/KTO) can demonstrate relative robustness in mathematical reasoning tasks. By contrast, SFT maintains stronger performance in complex, context-intensive tasks. These findings highlight that no single post-training strategy universally outperforms in all scenarios; the best choice depends on the type of target task and the nature of spurious correlations.

The emergence of Retrieval-augmented generation (RAG) has alleviated the issues of outdated and hallucinatory content in the generation of large language models (LLMs), yet it still reveals numerous limitations. When a general-purpose LLM serves as the RAG generator, it often suffers from inadequate response informativeness, response robustness, and citation quality. Past approaches to tackle these limitations, either by incorporating additional steps beyond generating responses or optimizing the generator through supervised fine-tuning (SFT), still failed to align with the RAG requirement thoroughly. Consequently, optimizing the RAG generator from multiple preference perspectives while maintaining its end-to-end LLM form remains a challenge. To bridge this gap, we propose Multiple Perspective Preference Alignment for Retrieval-Augmented Generation (PA-RAG), a method for optimizing the generator of RAG systems to align with RAG requirements comprehensively. Specifically, we construct high-quality instruction fine-tuning data and multi-perspective preference data by sampling varied quality responses from the generator across different prompt documents quality scenarios. Subsequently, we optimize the generator using SFT and Direct Preference Optimization (DPO). Extensive experiments conducted on four question-answer datasets across three LLMs demonstrate that PA-RAG can significantly enhance the performance of RAG generators. Our code and datasets are available at https://github.com/wujwyi/PA-RAG.

But, that longstanding partnership is now set to reach new heights as the popular sports league and the leading tech company will leverage AWS tools to develop a generative artificial intelligence-designed trophy for the upcoming Canadian Grand Prix. The first-of-its-kind approach to the trophy for the highly-anticipated event is expected to help increase creativity.

'The greatest track on Earth' finally finishes up at the Interlagos Circuit of the São Paulo Grand Prix. It features the Senna'S', an S-shaped part of the track named after the legendary Brazilian racing driver Ayrton Senna. Look closely and you'll see a statue of Senna, who was tragically killed at the 1994 San Marino Grand Prix when his car crashed into a concrete barrier. Bringing the AI track to an end in Brazil, the last section runs from Turn 14, known as Junção, and into Interlagos' final sector. Sky Sports, which has exclusive broadcast rights to live F1 races, is trying to entice fans to subscriptions before the Grand Prix season starts next month. The 2024 calendar comprises a record 24 Grands Prix, starting with the Bahrain Grand Prix on March 2. The Senna'S', named after the legendary Ayrton Senna, is renowned as one of Formula 1's most iconic overtaking spots Bringing the race to an end in Brazil, the thirteenth section of'The Greatest Track On Earth' runs from Turn 14, known as Junção, and into Interlagos' final sector Not content with winning trophies in real life, McLaren is now competing in the virtual world for F1 glory. The legendary British automobile company entered the world of eSports in 2017 and won its first tournament in December last year. With two Brits on the team, McLaren saw off fierce competitors including Mercedes-Benz, Aston Martin, Red Bull Racing and Haas. MailOnline has taken a trip to the global headwaters of McLaren in Woking, Surrey, to see what it takes to become a professional eSports driver.

The Fédération Internationale de l'Automobile (FIA), F1's governing body, says it will employ Computer Vision tech at the season-closing Abu Dhabi Grand Prix this weekend. Drivers know the exact lines to take at corners for optimal lap times, but sometimes racers go out of bounds as they try to gain an advantage, and officials need to check cars stay within track limits. Four people had to review around 1,200 potential violations in July's Austrian Grand Prix, and some track limit violations went unpunished in October's US Grand Prix. The FIA hopes to reduce the number of possible infringements officials manually review to around 50 per race. You can get these reports delivered daily direct to your inbox.
