Image classification with the CIFAR-10 dataset is a popular task in computer vision and machine learning. The CIFAR-10 dataset consists of 60,000 color images (32×32 pixels) across 10 different classes, with 6,000 images per class.
Performing image classification with the CIFAR-10 dataset involves several general steps and some important steps are here below:
- Load and preprocess the dataset: Begin by loading the CIFAR-10 dataset, which various machine learning libraries. Preprocess the dataset by normalizing the pixel values, and resizing or cropping images if necessary. It splits the data into training and validation sets.
- Design the model architecture: Choose a suitable model architecture for image classification, commonly using Convolutional Neural Networks (CNNs). You can design a custom CNN architecture or utilize pre-existing architectures. Like VGGNet, ResNet, or InceptionNet, readily available in deep-learning libraries.
- Train the model: Initialize the model with random weights and train it using the training set. Train the model by feeding batches of images, computing predictions, comparing them with the true labels, and updating the model’s parameters using optimization techniques like gradient descent. Typically, this process is performed for multiple epochs, iterating over the entire training set.
- Evaluate the model: After training, assess the model’s performance on the test set. Use the trained model to make predictions on the test images and compare them with the ground truth labels.This evaluation step helps determine how well the model generalizes to unseen data.
- Fine-tuning and hyperparameter tuning (optional): Depending on the initial model’s performance, fine-tune specific aspects of the architecture or experiment with different hyperparameter values to improve accuracy. This may involve adjusting learning rates, utilizing regularization techniques, or exploring data augmentation strategies to enhance the model’s performance.
- Predict new images: Once you have a trained and validated model, utilize it to predict the class labels of new, unseen images.
