Multi-Group Proportional Representation in Retrieval

Neural Information Processing Systems

Current approaches to mitigate these representational harms balance the number of retrieved items across population groups defined by a small number of (often binary) attributes. However, most existing methods overlook intersectional groups determined by combinations of group attributes, such as gender, race, and ethnicity.



The Shutdown Is Pushing Air Safety Workers to the Limit

WIRED

Federal employees say that flying is still safe despite the strain on air traffic controllers. But expect even more airport delays ahead. It hasn't been a good year for federal aviation safety workers. January saw the worst US commercial airline disaster in decades, quickly followed by sudden layoffs, staffing shortfalls, major technology glitches at one of the nation's busiest airports, and short timelines to rebuild the systems that govern national airspace. It somehow got worse this month, when a stalemate between congressional Republicans and Democrats led to a government shutdown.



Coded Computing for Resilient Distributed Computing: A Learning-Theoretic Framework

Neural Information Processing Systems

Coded computing has emerged as a promising framework for tackling significant challenges in large-scale distributed computing, including the presence of slow, faulty, or compromised servers. In this approach, each worker node processes a combination of the data, rather than the raw data itself. The final result then is decoded from the collective outputs of the worker nodes. However, there is a significant gap between current coded computing approaches and the broader landscape of general distributed computing, particularly when it comes to machine learning workloads. To bridge this gap, we propose a novel foundation for coded computing, integrating the principles of learning theory, and developing a framework that seamlessly adapts with machine learning applications. In this framework, the objective is to find the encoder and decoder functions that minimize the loss function, defined as the mean squared error between the estimated and true values. Facilitating the search for the optimum decoding and functions, we show that the loss function can be upper-bounded by the summation of two terms: the generalization error of the decoding function and the training error of the encoding function. Focusing on the second-order Sobolev space, we then derive the optimal encoder and decoder.
