Harshit Paramhans

Data science and machine learning. M.Tech from IIT Guwahati, where my thesis classified 15 hand postures from 8-channel surface EMG.

The thing I took from that work: the evaluation protocol decides the number. Correcting a leaky data split in my own thesis cost 14.5 accuracy points, and the corrected figure is the one I report. My projects spend as much effort on how a result was validated as on producing it.

Toolkit — Python (pandas, NumPy, SciPy, scikit-learn) · SQL / PostgreSQL · signal processing · embeddings and vector search · Tableau · Jupyter

Featured projects

Project What it does Stack
sEMG Hand Posture Classification M.Tech thesis — 15 postures from 8-channel EMG. 83.7% within-subject and 32.3% cross-subject against a 6.7% chance baseline; a leaky split had inflated the headline to 98% Python, scikit-learn, NMF, signal processing
Sales & Customer Analytics with SQL 15+ business questions answered on a digital music store database — customer behaviour, sales trends, revenue and genre popularity PostgreSQL, CTEs, window functions
Customer Segmentation — RFM + K-Means Segments online retail customers into high-value and at-risk groups to target marketing spend Python, scikit-learn, pandas
Hospital Mortality Prediction Analyses patient records to estimate in-hospital mortality risk SQL, Excel
IBM Data Science Capstone End-to-end capstone: data collection, wrangling, exploratory analysis, interactive visualisation and predictive modelling Python, pandas, scikit-learn, Folium, Plotly Dash
Semantic Book Recommender Natural-language book search over a vector database with zero-shot category and emotion filtering, served through a Gradio app. Retrieval quality is currently being measured — precision@k and MRR against hand labels — before I put numbers on it LLMs, embeddings, ChromaDB, Gradio
