 # Integer-Quantized Super Resolution Experiments with Brevitas
 
 This directory contains scripts demonstrating how to train integer-quantized super resolution models using Brevitas.
-Code is also provided to demonstrate accumulator-aware quantization (A2Q) as proposed in our ICCV 2023 paper "[A2Q: Accumulator-Aware Quantization with Guaranteed Overflow Avoidance](https://arxiv.org/abs/2308.13504)".
