Advancing AI research: Main conference papers

We have contributed to three papers accepted to the main conference track:

• Distributional Preference Alignment of LLMs via Optimal Transport: Distinguished Applied Researcher, Igor Melnyk, takes the lead as first-author exploring novel methods for aligning large language models (LLMs) with user preferences using optimal transport theory. This work enhances LLMs' ability to generate content that aligns with specific needs and values. 
• Searching for Efficient Linear Layers over a Continuous Space of Structured Matrices: VP of AI Research Bayan Bruss and Senior Machine Learning Engineer Christopher Ferri contribute their expertise to this collaborative research with NYU, which focuses on optimizing the efficiency of neural networks by exploring a continuous space of structured matrices for linear layers. This has the potential to lead to faster and more efficient models.
• Tiny Time Mixers (TTMs): Fast Pre-trained Models for Enhanced Zero/Few-Shot Forecasting of Multivariate Time Series: In partnership with IBM Corp, Senior Distinguished Applied Researcher Nam Nguyen helps to introduce innovative techniques for time series forecasting with Tiny Time Mixers (TTMs). These pre-trained models are optimized for fast and accurate predictions, even with limited fine-tuning data.

Dr. Furong Huang, our inaugural Visiting Scholar and an Associate Professor in Computer Science at the University of Maryland, also contributed to six additional NeurIPS papers. Dr. Huang’s expertise in trustworthy machine learning strengthens our research collaborations and reflects our commitment to bridging academia and industry. 

Fostering the next generation of AI talent: Workshop papers

Capital One's presence at NeurIPS extends beyond the main conference with seven accepted workshop papers, further demonstrating our commitment to advancing AI research and fostering the next generation of AI talent through our internship programs. 

Applied Research Internship Program (ARIP)

Five of the accepted papers are authored by talented individuals from our 2024 Applied Research Internship Program (ARIP), a program designed to provide PhD students with hands-on experience tackling real-world AI challenges in the financial sector. 

• Refusal Tokens: A Simple Way to Calibrate Refusals in Large Language Models: This paper explores a novel method for controlling the refusal behavior of large language models by introducing "refusal tokens" during training. This technique allows for fine-grained control over the model's tendency to refuse certain prompts or questions, enhancing safety and reliability.
• Dense Backpropagation Improves Routing for Sparsely-Gated Mixture of Experts: This paper investigates the use of dense backpropagation in Mixture of Experts (MoE) models, demonstrating its effectiveness in improving routing decisions and overall model performance. This work contributes to the advancement of MoE models, which are known for their efficiency and scalability.
• Language Model Scaling Laws and Zero-sum Learning: This research delves into the relationship between language model scaling laws and zero-sum learning, exploring how the competitive dynamics of zero-sum games can influence the scaling behavior and performance of large language models.
• StructMoE: Augmenting MoEs with Hierarchically Routed Low Rank Experts: This paper proposes StructMoE, a novel architecture that enhances Mixture of Experts (MoE) models by incorporating hierarchically routed low-rank experts. This approach aims to improve the efficiency and expressiveness of MoE models, further advancing their capabilities in various applications.

Data Science Internship Program (DSIP)

We are also proud to highlight a workshop paper authored by a former intern from our Data Science Internship Program (DSIP), which offers aspiring data scientists the opportunity to contribute to cutting-edge research and development.

• Enhancing Table Representations with LLM-powered Synthetic Data Generation: This paper explores the use of large language models (LLMs) to generate synthetic tabular data for improving table representations. This approach aims to enhance the performance of similar table recommendation systems, which are crucial for efficient data management and analysis in data-driven enterprises. The research introduces a novel synthetic data generation pipeline that leverages LLMs to create a large-scale dataset tailored for table-level representation learning, leading to improved accuracy in recommending similar tables.

Collaborative research

Finally, we have workshop papers co-authored by Senior Distinguished Applied Researcher Nam Nguyen, and Distinguished Applied Researcher Supriyo Chakraborty further demonstrating our commitment to collaborative research and knowledge sharing within the AI community.

• Scaling-laws for Large Time-series Models: This research, conducted in collaboration with Johns Hopkins University, explores the scaling laws that govern the performance of large time-series models. By examining the relationships among model size, data volume, and computational resources, this study offers valuable insights into the efficient training and deployment of these models for diverse time-series forecasting tasks in finance and other domains.
• MyCroft: Towards Effective and Efficient External Data Augmentation: This research introduces MyCroft, a new data-efficient framework implementing techniques to evaluate relative utility of  relevant external data sources that can augment internal data to improve model performance. These techniques leverage feature space distances and gradient matching to identify small but informative data subsets to maximize performance with minimal data exposure.
