TopoQuant: Topological Framework to Characterize Behavioral Shifts in Quantized Large Language Models
Baha Rababah, Shahzeb Qamar, Lorenz Sparrenberg +4
Post-training quantization (PTQ) reduces the com putational cost of large language models (LLMs), but it can introduce internal structural and behavioral changes that are not captu…

The Illusion of Equivalency: Statistical Characterization of Quantization Effects in LLMs
Baha Rababah, Shahzeb Qamar, Lorenz Sparrenberg +4
Post-Training Quantization has become widely used to compress large language models to make them deployable on resource-constrained devices. However, the evaluation of quantization…
