Feb 2025 — PresentBuilt NLP, OCR, and animal-monitoring computer-vision systems, and a scientific data pipeline for testing solar–seismic associations.
• Built an end-to-end Russian-language NLP pipeline over 125,894 Telegram messages (86,316 after dedup and URL-only removal), fine-tuning RuBERT into a 3-class behavioral-text classifier: 0.84 macro-F1 on a lexicon-stratified eval set, random held-out macro-F1 on a random held-out sample. Labels were bootstrapped through an LLM-assisted pipeline and audited by blind human re-annotation (Cohen’s κ = 0.81); scored the full cleaned corpus for downstream event analysis.
