Low-bit Shift Network for End-to-End Spoken Language Understanding
Bibliographic record
Abstract
Deep neural networks (DNN) have achieved impressive success in multiple domains.Over the years, the accuracy of these models has increased with the proliferation of deeper and more complex architectures.Thus, state-of-the-art solutions are often computationally expensive, which makes them unfit to be deployed on edge computing platforms.In order to mitigate the high computation, memory, and power requirements of inferring convolutional neural networks (CNNs), we propose the use of power-of-two quantization, which quantizes continuous parameters into low-bit power-of-two values.This reduces computational complexity by removing expensive multiplication operations and with the use of low-bit weights.ResNet is adopted as the building block of our solution and the proposed model is evaluated on a spoken language understanding (SLU) task.Experimental results show improved performance for shift neural network architectures, with our low-bit quantization achieving 98.76 % on the test set which is comparable performance to its full-precision counterpart and state-of-the-art solutions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
