Machine Learning Scientist at Lightmatter (September 2018 - November 2020)

Fine-tuningFine-tuning

Worked as a Machine Learning Scientist developing techniques to improve low-precision neural network inference and training. Contributed to algorithmic advances that would support model training workflows. Supported deployment-ready training improvements for hybrid photonic-electronic matrix processors. • Developed improved low-precision training/inference approaches. • Contributed to patentable algorithm and hardware architecture work. • Focused on training-time techniques rather than data labeling. • Collaborated on AI accelerator-related model performance improvements.

2018 - 2020

Machine Learning Scientist at Gamalon, Inc. (October 2015 - August 2018)

ClassificationClassification

Developed machine learning systems including recurrent neural networks and hierarchical Bayesian nonparametric models used for entity resolution and product description parsing. The work supported automated understanding pipelines that rely on supervised training objectives. Data labeling is not explicitly described, but the role is clearly focused on ML model training and deployment for NLP tasks. • Built and deployed ML models for entity resolution. • Implemented hierarchical Bayesian nonparametric approaches. • Applied recurrent neural networks to NLP parsing tasks. • Supported natural language understanding use cases.
