Deterministic Recursive Waveform Reconstruction and Proportional Mapping

Christian Heinrich Hohlfeld 2024 check_circle Published

Abstract. This paper introduces the Hohlfeld Data Representation (HDR) method, a framework for encoding data using residual vectors. By defining data points through length and angle relative to a reference vector, the method aims for 100% deterministic stability and exact reconstruction without approximation artifacts common in Fourier-based methods. Primary applications include lossless signal compression and cryptographic seed generation.

PhO-Compress: A Two-Stage Framework to Enhance Optical LLM Context Compression

Christian Heinrich Hohlfeld 2024 check_circle Published

Abstract. Addressing the bandwidth limitations in Optical Large Language Models (O-LLMs), this research proposes a two-stage compression framework. The methodology optimizes photon-based data transmission windows, significantly reducing latency in high-throughput optical computing environments.
