Plant Disease Detection System Introduction | Image Classification Project | Overview of Project
Summary
TLDRIn this video, we embark on a journey to create a deep learning model for predicting plant diseases from RGB images of crop leaves. The dataset contains 87,000 images across 38 classes, split into training and validation sets. Key challenges such as underfitting, overfitting, and overshooting during model training will be addressed. The model's performance will be evaluated using metrics like accuracy, precision, recall, and a confusion matrix. This project serves as a valuable resource for those interested in machine learning and data science, equipping viewers with practical knowledge for interviews and real-world applications.
