SUMMARY: This project aims to construct a predictive model using a TensorFlow convolutional neural network (CNN) and document the end-to-end steps using a template. The PlantaeK Jammu Kashmir Leaf dataset is a binary classification situation where we attempt to predict one of the two possible outcomes.

INTRODUCTION: This dataset contains 2153 healthy and unhealthy plant leaf images for eight different fruits and vegetables. The plants taken for study are the native plants of the Kashmir region of India. Eight different plants, namely Apple, Apricot, Cherry, Cranberry, Grapes, Peach, Pear, and Walnut, are selected for the study based on their commercial and medicinal usage. The leaf is the primary object of reference taken for making the database, as they grow much earlier than fruits and the other plant parts.

In iteration Take1, we constructed a CNN model based on the InceptionV3 architecture to predict the leaf’s health state based on the available images.

In this Take2 iteration, we will construct a CNN model based on the DenseNet architecture to predict the leaf’s health state based on the available images.

ANALYSIS: In iteration Take1, the InceptionV3 model’s performance achieved an accuracy score of 95.07% after ten epochs using the training dataset. The same model processed the validation dataset with an accuracy score of 79.72%.

In this Take2 iteration, the DenseNet model’s performance achieved an accuracy score of 92.23% after ten epochs using the training dataset. The same model processed the validation dataset with an accuracy score of 75.06%.

CONCLUSION: In this iteration, the DenseNet-based CNN model appeared to be suitable for modeling this dataset. We should consider experimenting with TensorFlow for further modeling.
