Inference Variability in Text Classifiers Despite Fixed Inputs and Models

Research shows that deterministic inference in text classifiers can be disrupted by factors like batch size, hardware, and inference engine, causing different outputs from the same input. This nondeterminism is partly due to floating-point non-associativity and shape-dependent computations.

AI-assisted summary based on the listed source.

Deterministic inference is essential for reliable and trustworthy machine learning. Prior studies of text generation have shown that changing factors such as batch size, batch composition, hardware, or inference engine can alter the generated text, even when the prompt, model parameters, and sampling randomness...

Reliable and trustworthy machine learning depends on consistent inference results, but this study highlights challenges in achieving determinism in text classification. Understanding these factors is crucial for improving model reliability in production environments.

Hardware and robotics watchers may want to track whether this becomes a product, benchmark, or deployment signal.
