How to classify images using CIFAR10 dataset in Keras
Classifying images using the CIFAR-10 dataset in Keras involves several steps. First, you need to import the CIFAR-10 dataset, which is a dataset of 60,000 color images of 32×32 pixels, divided into 10 classes. Each image belongs to one of the following classes: airplanes, cars, birds, cats, deer, dogs, frogs, horses, ships, and trucks.
After that, you will need to define the model architecture. The architecture of the model is the structure of the layers and the number of units or neurons in each layer. This can be done using the Sequential class in Keras and adding layers to it. The architecture should be appropriate for the specific task of image classification.
After that, you will need to choose the optimizer and the learning rate. The optimizer is used to adjust the weights of the model to minimize the loss function and the learning rate controls the step size that the optimizer takes in the direction of the gradient.
You will also need to decide the evaluation metrics that you will use to evaluate the model performance. The most common evaluation metrics for classification models include accuracy, precision, recall, and F1 score.
Finally, you will need to decide the number of training iterations (epochs) and the batch size. The number of epochs controls the number of times the model will see the entire dataset during training, while the batch size controls the number of samples that the model sees at a time.
In summary, classifying images using the CIFAR-10 dataset in Keras involves importing the dataset, preprocessing the data, defining the model architecture, choosing the optimizer and learning rate, deciding the evaluation metrics, and deciding the number of training iterations and batch size. The goal of this experiment is to train a deep learning model that is able to classify images of airplanes, cars, birds, cats, deer, dogs, frogs, horses, ships, and trucks with a high level of accuracy.
