Smart Sensors: 1D-CNNs and Signal Processing for Spectroscopy

To equip researchers with AI-driven techniques using 1D-CNNs and signal processing to enhance spectral data analysis, improving classification, denoising, and trace detection in Raman, Fluorescence, and IR spectroscopy.

📅 Day 1 — Spectral Preprocessing & Augmentation

• Lecture: Overview of spectral data cleaning—baseline correction, smoothing, and the importance of data augmentation for improving model robustness.
• Lab: Hands-on experience with Python (scipy.signal) to preprocess raw Raman/Fluorescence spectra and apply augmentation techniques like synthetic noise and shifts.
