An Evaluation Dataset for Intent Classification and Out-of-Scope Prediction
Stefan Larson,Anish Mahendran,Joseph Peper,Christopher Clarke,Andrew Lee,Parker Hill,Jonathan K. Kummerfeld,Kevin Leach,Michael A. Laurenzano,Lingjia Tang,Jason Mars +10 more
TL;DR: A new dataset is introduced that includes queries that are out-of-scope—i.e., queries that do not fall into any of the system’s supported intents, posing a new challenge because models cannot assume that every query at inference time belongs to a system-supported intent class.

DeftNN: addressing bottlenecks for DNN execution on GPUs via synapse vector elimination and near-compute data fission
Parker Hill,Animesh Jain,Mason Hill,Babak Zamirai,Chang-Hong Hsu,Michael A. Laurenzano,Scott Mahlke,Lingjia Tang,Jason Mars +8 more
TL;DR: DeftNN is a GPU DNN execution framework that targets the key architectural bottlenecks of DNNs on GPUs to automatically and transparently improve execution performance, and is composed of two novel optimization techniques– synapse vector elimination, a technique that identifies non-contributing synapses in the DNN and carefully transforms data and removes the computation and data movement.
Proceedings ArticleDOI
Input responsiveness: using canary inputs to dynamically steer approximation
TL;DR: This paper introduces Input Responsive Approximation, an approach that uses a canary input — a small program input carefully constructed to capture the intrinsic properties of the original input — to automatically control how program approximation is applied on an input-by-input basis.

An Evaluation Dataset for Intent Classification and Out-of-Scope Prediction.
Stefan Larson,Anish Mahendran,Joseph Peper,Christopher Clarke,Andrew Lee,Parker Hill,Jonathan K. Kummerfeld,Kevin Leach,Michael A. Laurenzano,Lingjia Tang,Jason Mars +10 more
TL;DR: The authors introduce a new dataset that includes queries that are out-of-scope, i.e., queries that do not fall into any of the system's supported intents, and evaluate a range of benchmark classifiers on this dataset along with several different out-ofthe-scope identification schemes.
Proceedings ArticleDOI
Concise loads and stores: the case for an asymmetric compute-memory architecture for approximation
Animesh Jain,Parker Hill,Shih-Chieh Lin,Muneeb Khan,Emdadul Haque,Michael A. Laurenzano,Scott Mahlke,Lingjia Tang,Jason Mars +8 more
TL;DR: This paper introduces a novel approximate computing technique that decouples the format of data in the memory hierarchy from the format in the compute subsystem to significantly reduce the cost of storing and moving bits throughout theMemory hierarchy and improve application performance.
