Hi πŸ‘‹, I'm Harsh Rathva

Machine Learning Researcher β€” NLP Safety β€’ Multilingual Data β€’ Multi-Agent RL β€’ AI Alignment


πŸ‘¨β€πŸ”¬ About Me

I'm interested in building reliable, scalable, and aligned AI systems, with a research focus spanning two connected areas:

1️⃣ NLP Safety & Multilingual Dataset Curation

  • Multilingual hallucination detection
  • Scientific factuality classification
  • Large-scale dataset balancing & augmentation
  • Cross-lingual model evaluation
  • LLM reliability & safety

2️⃣ Multi-Agent Reinforcement Learning & AI Alignment

  • Internal alignment embeddings (ESAI)
  • Counterfactual harm forecasting
  • Graph diffusion & attention gating
  • Zero-shot population scaling
  • Stability of cooperative policies

I enjoy working at the intersection of LLMs, distributed training, MARL, and alignment-focused architectures.
