Curriculum vitae

B.Tech, Computer Science and Engineering (Internet of Things and Cyber Security including Block Chain Technology), Heritage Institute of Technology, Kolkata.

National Gems Higher Secondary School, Kolkata.

Jadavpur University, Kolkata. Research collaborator, multilingual NLP. Co-authoring a manuscript (in preparation) with Prof. Sudip Naskar and a TU Munich collaborator.

• Built a reproducible round-trip evaluation (14 Indic languages, two translation-model families, 56,000 translations) measuring whether honorific register survives a pivot through English, on 4-bit local models and free-tier GPUs.
• Identified a systematic deference floor: IndicTrans2 kept 99% of deferential source register (1,659/1,677) but 6% of less-deferential register (71/1,188) among classified outputs; native-speaker validation of cue tables for 12 of 14 languages is pending.
• Showed that dedicated MT's near-zero pivot penalty is a floor artefact, since its direct path already drops almost all less-deferential register, while LLM translators lose 20–22 points through their own English pivot.
• Wrote LLM-free, rule-based register extractors (one cue table per language) and a Unicode normalization policy that fixed four silent under-counting bugs; froze datasets behind hash checks and made every pipeline resumable and seeded.
• Preregistered predictions before each phase and reported two that failed: the original contextual-fraction predictor did not survive robustness checks, and the target-decoder-prior test failed with a flawed metric; a corrected confirmatory re-test is preregistered.
