Research Paper
Core Innovation
This paper presents I-Segmenter, a Vision Transformer segmentation model fully operating with integer-only arithmetic, eliminating floating-point operations to reduce resource use. It introduces λ-ShiftGELU, a novel activation function that stabilizes quantization, and removes layers incompatible with integer-only execution. This enables near-baseline accuracy with significantly smaller model size and faster inference on constrained hardware.

Research Paper Overview
I-Segmenter: Integer-Only Vision Transformer for Efficient Semantic Segmentation
Summary
Vision Transformers (ViTs) excel in semantic segmentation but are resource-heavy for constrained devices. I-Segmenter introduces a fully integer-only ViT segmentation framework replacing floating-point operations to reduce memory and computation. It features a novel activation function, λ-ShiftGELU, to stabilize quantization and removes layers incompatible with integer-only execution. This approach achieves near-baseline accuracy with up to 3.8x smaller model size and 1.2x faster inference, even with minimal calibration data.
