HAS-VQ: Hessian-Adaptive Sparse Vector Quantization for High-Fidelity LLM Compression

Vladimer Khasia

Post-training quantization is essential for deploying Large Language Models (LLMs) on resource-constrained devices. However, standard integer quantization (e.g., INT4) fundamentall…

Dynamic Subspace Composition: Efficient Adaptation via Contractive Basis Expansion

Vladimer Khasia

Mixture of Experts (MoE) models scale capacity but often suffer from representation collapse and gradient instability. We propose Dynamic Subspace Composition (DSC), a framework th…

DeepVekua: Geometric-Spectral Representation Learning for Physics-Informed Fields

Vladimer Khasia

We present DeepVekua, a hybrid architecture that unifies geometric deep learning with spectral analysis to solve partial differential equations (PDEs) in sparse data regimes. By le…

The Adaptive Vekua Cascade: A Differentiable Spectral-Analytic Solver for Physics-Informed Representation

Vladimer Khasia

Coordinate-based neural networks have emerged as a powerful tool for representing continuous physical fields, yet they face two fundamental pathologies: spectral bias, which hinder…

The Vekua Layer: Exact Physical Priors for Implicit Neural Representations via Generalized Analytic Functions

Vladimer Khasia

Implicit Neural Representations (INRs) have emerged as a powerful paradigm for parameterizing physical fields, yet they often suffer from spectral bias and the computational expens…
