About Program:
“AI for Pest & Disease Detection: Build an Image Classifier” is a fully hands-on, project-based workshop where participants learn how to turn simple leaf photos into an AI-powered decision-support tool for farmers. Using Google Colab, Python, and transfer learning (e.g., MobileNet/ResNet), you will work step-by-step with real plant health images to build, train, and test an image classifier that can flag likely diseases and suggest advisory messages.
Aim: This hands-on workshop aims to equip participants with the practical skills to build, evaluate, and responsibly use an AI-based image classifier for crop pest and disease detection—starting from raw leaf images and ending with a simple “farmer-facing” decision-support flow.
Program Objectives:
- Introduce participants to the fundamentals of AI-based pest and disease detection using leaf images.
- Enable participants to explore, organise and assess the quality of plant health image datasets in Google Colab.
- Guide participants in building a transfer learning–based image classifier for crop pest/disease classes.
- Develop the ability to interpret model predictions (class + confidence) and link them to simple advisory messages for farmers.
- Create awareness about the risks, limitations and biases of image-only AI diagnosis, and the need for human expert validation.
- Encourage participants to design a practical deployment flow (app/WhatsApp bot + agronomist) for real-world extension use.
What you will learn?
📅 Day 1 – Data & Image Classification Basics (Hands-on)
- Problem framing: farmer takes a picture → app gives “likely disease + advice”.
- Hands-on: mount Google Drive in Colab, list images, show sample images with matplotlib.
- Image quality discussion: lighting, angle, noise and their effect on model performance.
- Mini dataset tour: folder structure (healthy/, diseased/ or 3–4 classes).
- Quick reflection: limitations of AI purely from images.
- Hands-on take-home: Colab notebook 01_pest_image_dataset_exploration.ipynb + folder with labelled training images.
📅 Day 2 – Build & Train a Simple Classifier (Transfer Learning, Hands-on Lab)
- Concept input: what is transfer learning and why it helps with small datasets.
- Hands-on: load a pre-trained model (e.g., MobileNet/ResNet) and freeze base layers.
- Model head: add a small dense classification layer for pest/disease classes.
- Training lab: train for a few epochs and view accuracy/loss curves.
- Hands-on quick test: upload a new leaf image and see the predicted class.
- Hands-on take-home: Colab notebook 02_pest_classifier_training.ipynb + first working “AI diagnosis” model (even if rough).
📅 Day 3 – Responsible Use & Deployment Ideas (Hands-on Design & Reporting)
- Discussion: error, bias & impact – misclassification → wrong spraying advice and farmer risk.
- Hands-on: add a prediction report cell (predicted class, confidence, advisory template text).
- Hands-on design exercise: sketch an app/WhatsApp bot flow using this model.
- Human in the loop: integrate agronomist/extension worker validation into the flow.
- Closing: how to extend – more classes, multilingual advisory, integration with helplines.
- Hands-on take-home: Colab notebook 03_pest_classifier_reporting_and_flow.ipynb + app-flow diagram for project documentation.
