Bipartite Ranking From Multiple Labels: On Loss Versus Label Aggregation

Michal Lukasik, Lin Chen, Harikrishna Narasimhan +7

Bipartite ranking is a fundamental supervised learning problem, with the goal of learning a ranking over instances with maximal Area Under the ROC Curve (AUC) against a single bina…

Universal Model Routing for Efficient LLM Inference

Wittawat Jitkrittum, Harikrishna Narasimhan, Ankit Singh Rawat +9

Model routing is a simple technique for reducing the inference cost of large language models (LLMs), wherein one maintains a pool of candidate LLMs, and learns to route each prompt…

Cascade-Aware Training of Language Models

Congchao Wang, Sean Augenstein, Keith Rush +5

Reducing serving cost and latency is a fundamental concern for the deployment of language models (LMs) in business applications. To address this, cascades of LMs offer an effective…

Faster Cascades via Speculative Decoding

Harikrishna Narasimhan, Wittawat Jitkrittum, Ankit Singh Rawat +4

Cascades and speculative decoding are two common approaches to improving language models' inference efficiency. Both approaches involve interleaving models of different sizes, but…

Language Model Cascades: Token-level uncertainty and beyond

Neha Gupta, Harikrishna Narasimhan, Wittawat Jitkrittum +3

Recent advances in language models (LMs) have led to significant improvements in quality on complex NLP tasks, but at the expense of increased inference costs. Cascading offers a s…

Regression-aware Inference with LLMs

Michal Lukasik, Harikrishna Narasimhan, Aditya Krishna Menon +2

Large language models (LLMs) have shown strong results on a range of applications, including regression and scoring tasks. Typically, one obtains outputs from an LLM via autoregres…

Distributionally Robust Post-hoc Classifiers under Prior Shifts

Jiaheng Wei, Harikrishna Narasimhan, Ehsan Amid +3

The generalization ability of machine learning models degrades significantly when the test distribution shifts away from the training distribution. We investigate the problem of tr…

When Does Confidence-Based Cascade Deferral Suffice?

Wittawat Jitkrittum, Neha Gupta, Aditya Krishna Menon +3

Cascades are a classical strategy to enable inference cost to vary adaptively across samples, wherein a sequence of classifiers are invoked in turn. A deferral rule determines whet…

Plugin estimators for selective classification with out-of-distribution detection

Harikrishna Narasimhan, Aditya Krishna Menon, Wittawat Jitkrittum +1

Real-world classifiers can benefit from the option of abstaining from predicting on samples where they have low confidence. Such abstention is particularly useful on samples which…

Consistent Multiclass Algorithms for Complex Metrics and Constraints

Harikrishna Narasimhan, Harish G. Ramaswamy, Shiv Kumar Tavker +3

We present consistent algorithms for multiclass learning with complex performance metrics and constraints, where the objective and constraints are defined by arbitrary functions of…

Robust Distillation for Worst-class Performance

Serena Wang, Harikrishna Narasimhan, Yichen Zhou +3

Knowledge distillation has proven to be an effective technique in improving the performance a student model using predictions from a teacher model. However, recent work has shown t…

Optimal Auctions through Deep Learning: Advances in Differentiable Economics

Paul Dütting, Zhe Feng, Harikrishna Narasimhan +2

Designing an incentive compatible auction that maximizes expected revenue is an intricate task. The single-item case was resolved in a seminal piece of work by Myerson in 1981, but…
