LLark: A Multimodal Instruction-Following Language Model for Music

1 code implementation11 Oct 2023 Josh Gardner, Simon Durand, Daniel Stoller, Rachel M. Bittner

Music has a unique and complex structure which is challenging for both expert humans and existing AI systems to understand, and presents unique challenges relative to other forms of audio.

Benchmarking Distribution Shift in Tabular Data with TableShift

1 code implementation NeurIPS 2023 Josh Gardner, Zoran Popovic, Ludwig Schmidt

However, high-quality benchmarks for distribution shift in tabular machine learning tasks are still lacking despite the widespread real-world use of tabular data and differences in the models used for tabular data in comparison to text and images.

Driving with Data: Modeling and Forecasting Vehicle Fleet Maintenance in Detroit

1 code implementation18 Oct 2017 Josh Gardner, Danai Koutra, Jawad Mroueh, Victor Pang, Arya Farahi, Sam Krassenstein, Jared Webb

Understanding the existence of patterns and trends in this data could be useful to a variety of stakeholders, particularly as Detroit emerges from Chapter 9 bankruptcy, but the patterns in such data are often complex and multivariate and the city lacks dedicated resources for detailed analysis of this data.

Subgroup Robustness Grows On Trees: An Empirical Baseline Investigation

1 code implementation23 Nov 2022 Josh Gardner, Zoran Popović, Ludwig Schmidt

Researchers have proposed many methods for fair and robust machine learning, but comprehensive empirical evaluation of their subgroup robustness is lacking.

Cross-Institutional Transfer Learning for Educational Models: Implications for Model Performance, Fairness, and Equity

1 code implementation1 May 2023 Josh Gardner, Renzhe Yu, Quan Nguyen, Christopher Brooks, Rene Kizilcec

We also find that stacked ensembling provides no additional benefits to overall performance or fairness compared to either a local model or the zero-shot transfer procedure we tested.

Dropout Model Evaluation in MOOCs

no code implementations16 Feb 2018 Josh Gardner, Christopher Brooks

The field of learning analytics needs to adopt a more rigorous approach for predictive model evaluation that matches the complex practice of model-building.

MORF: A Framework for Predictive Modeling and Replication At Scale With Privacy-Restricted MOOC Data

no code implementations16 Jan 2018 Josh Gardner, Christopher Brooks, Juan Miguel L. Andres, Ryan Baker

MORF has the potential to accelerate and democratize research on its massive data repository, which currently includes over 200 MOOCs, as demonstrated by initial research conducted on the platform.
