Image classification is the objective of identifying whether the image belongs to a particular predefined class or not. It's of vital importance in this era. latest advances in that field enabled self driving cars to be a reality, doctors to detect diseases, and people with disabilities to have a better life. Image classification can be extended to Image detection - detect whether something exists in an image - , and image recognition - which is the ability of software to identify objects, places, people, writing and actions in images. In this paper we tackle the challenge of classifying the 100 classes of the CIFAR-100 large dataset by providing two solutions (namely, MCSVM and Deep Conv Net) and explain our methods, show the results, and discuss how we achieved them.
It's required to classify 100 classes of objects found in images of the CIFAR-100 dataset, which contains 50000 training example and 10000 test samples. Images are of size 32x32x3 RGB colored 3-channels images.
In this paper we propose to solutions to the classification problem:
- Multi-Class SVM: in the form of a shallow neural network with the number of hidden units (in the hidden layer) equal to the number of classes and using the catagorical_hinge_loss as the loss function of the model. The model acheives relatively poor performance which we try to enhance in the next proposed model.
- Deep Neurak Network: we introduce a deep neural network withseveral convoluntional layers to extract and capture the many features of the images, which resulted in a better performance.
- This Notebook is developed totally in Python, we used keras API of the tensorflow 2.0 framework for building deeplearning models.
- we used the Eager mode of tensorflow via its sequential API for its simpilicity.
- Numpy for calculations
- Pandas for data preprocessing
- matplotlib for plotting figures
- scikit-learn for feature extraction
