In this example, the CNN model that was loaded was trained to solve a 1000-way classification problem. This example shows how to use a pretrained Convolutional Neural Network (CNN) as a feature extractor for training an image category classifier. I have created my own custom car vs bus classifier with 100 images of each category. These are a series of convolutional layers, interspersed with rectified linear units (ReLU) and max-pooling layers [2]. Well, then this tutorial is going to be a bit different and a whole lot interesting. Split the sets into training and validation data. We will then compare the true labels of these images to the ones predicted by the classifier. In this paper, we explore and compare multiple solutions to the problem of data augmentation in image classification. The Intel Image Classification dataset is a multi-class classification situation where we attempt to … I have split the data as shown-. Learn how to resize images for training, prediction, and classification, and how to preprocess images using data augmentation, transformations, and specialized datastores. The intermediate layers make up the bulk of the CNN. [2] Krizhevsky, Alex, Ilya Sutskever, and Geoffrey E. Hinton. 2018 Oct;24(10):1559-1567. doi: 10.1038/s41591-018-0177-5. [4] Donahue, Jeff, et al.
