PROFILE
Benedikt Hilmes
Worked on the rwth-i6/i6_experiments repository to design and optimize advanced speech recognition pipelines, focusing on model training, evaluation, and hardware-aware deployment. Leveraged Python and PyTorch to implement configurable experiments for CTC, HuBERT, and Conformer architectures, integrating quantization, distillation, and memristor-based optimizations. Enhanced data processing throughput and reproducibility by refactoring experimental setups, expanding parameter search spaces, and improving reporting workflows. Introduced Transformer-based language modeling and noise-handling configurations to support robust benchmarking. The work enabled systematic exploration of architectures and training strategies, accelerated iteration cycles, and established a foundation for energy-efficient, production-ready speech recognition on novel hardware platforms.
