This is the source code of the experiment described in chapter Deep Learning for Plant Diseases: Detection and Saliency Map Visualisation in a book Human and Machine Learning, 2018.

Training and evaluating state-of-the-art deep architectures for plant disease classification task using pyTorch.
Models are trained on the preprocessed dataset which can be downloaded here.
Dataset is consisted of 38 disease classes from PlantVillage dataset and 1 background class from Stanford's open dataset of background images - DAGS.
80% of the dataset is used for training and 20% for validation.

1. Train all the models with train.py and store the evaluation stats in stats.csv: python3 train.py
2. Plot the models' results for every archetecture based on the stored stats with plot.py: python3 plot.py

The models on the graph were retrained on final fully connected layers only - shallow, for the entire set of parameters - deep or from its initialized state - from scratch.

NOTE: All the others results are stored in stats.csv

Train the new model or download pretrained models on 10 classes of Tomato from PlantVillage dataset: AlexNet or VGG13.

Occlusion experiments for producing the heat maps that show visually the influence of each region on the classification.

Produce the heat map and plot with occlusion.py and store the visualizations in output_dir:

python3 occlusion.py /path/to/dataset /path/to/output_dir model_name.pkl /path/to/image disease_name

Early blight - original, size 80 stride 10, size 100 stride 10 Late blight - original, size 80 stride 10, size 100 stride 10 Septoria leaf spot - original, size 50 stride 10, size 100 stride 10

Saliency map is an analytical method that allows to estimate theimportance of each pixel, using only one forward and one backward pass through the network.

Produce the visualization and plot with saliency.py and store the visualizations in output_dir:

python3 occlusion.py /path/to/model /path/to/dataset /path/to/image class_name
