Hello, I'm
Arnol P S
Senior Data Scientist & AI/ML Researcher
About Me
I'm a Data Scientist and AI/ML Engineer with 5+ years of experience designing and deploying production-grade machine learning systems.
My expertise spans Computer Vision, Vision-Language Models, Deep Learning, and Natural Language Processing. I've led patent-pending research on biometric identification combining wavelet-based image enhancement with DINOv2 feature extraction and vector similarity search.
Currently, I'm building AI-powered enterprise solutions including multi-agent systems, RAG pipelines, and conversational AI platforms. I'm passionate about pushing the boundaries of what's possible with multimodal AI.

Research
Patent-pending innovations in computer vision and biometrics
Biometric Cattle Identification System
Computer vision system for individual cattle identification using muzzle patterns as biometric markers, analogous to human fingerprint recognition.
Problem
RFID-based livestock identification is susceptible to tampering, loss, and requires time-consuming manual verification.
Solution
Non-invasive, tamper-proof biometric identification using deep learning and novel image enhancement techniques.
Technical Pipeline
Key Innovation
Novel wavelet-based ridge enhancement algorithm adapting fingerprint recognition techniques (BayesShrink denoising, biorthogonal wavelet contrast enhancement, morphological skeletonization) for biological pattern extraction.
Research conducted at Digital University Kerala
with literature review of 27 academic references.
Dataset creation, model training, and end-to-end system architecture designed and implemented independently.
