Image Classification Model

Image classification introduction

Image classification is to identity what an image represents, to predict the object list and the probabilities. For example，the following table shows the classification results after mode inference.

Category	Probability
plant	0.9359
flower	0.8641
tree	0.8584
houseplant	0.7867
