A 3 Layer CNN architecture was used in this work to achieve 98.92% training accuracy and 0.02 training loss and a maximum test accuracy of 90.77% in
Significant developments and improvements in the area of image classification are revealed by an analysis of the architecture of deep learning algorithms.
A pioneer architecture for computer vision LeNet was introduced in the 1990s, which used the convolution operation to automatically learn
And since the goal of this article is to help practitioners to choose the model architecture for real-world computer vision problems, supervised image classification using ConvNets is what we will focus on. On the other hand, if training cost and prediction latency are not a concern for your project, and you are after the highest accuracy, you might want to choose the largest/fanciest model or even consider an ensemble of several model architectures. VGG architectures have also been found to learn hierarchical elements of images like texture and content, making them popular choices for training style transfer models. Given a goal (e.g., model accuracy) and constraints (network size or inference latency), these methods rearrange composable blocks of layers to form new architectures. Use open-source tools and transfer learning to quickly implement and train other candidate architectures to see if they can outperform your baseline model or offer complexity improvements.
The methodology includes clearly defined phases: data acquisition, data pre-processing, training, and evaluation.Figure 1 provides a comprehensive overview of this process.The image datasets used—BSL, BSL-40, ISL-alpha char, ASL, KU-BdSL, blood cells, MRI tumor, tumor categorization, and DeepHisto—were prepared using standardized procedures adapted to each dataset’s characteristics.These preprocessed images were then input into the DeepFreqNet architecture, which was developed from the ground up.The architecture was trained to recognize a wide range of features, textures, and patterns across large-scale datasets, enabling improved performance and generalization across various visual domains. The proposed DeepFreqNet architecture in Fig. 4 is an advanced neural network refined for efficient multi-class image classification by incorporating multiple deep learning techniques, each optimized for different feature extraction scales and computational efficiency. Performance-wise, DeepFreqNet achieves strong results across diverse domains, including medical imaging (e.g., MRI tumors, histopathology slides, blood cell classification) and hand sign recognition (BSL, ISL, ASL), demonstrating not only high accuracy but also computational efficiency and rapid convergence.
Two main architectures are prevalent in image classification: traditional Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs). Modern image classification algorithms primarily use Transformers and Convolutional Neural Networks (CNNs). However, there is a hybrid architecture that combines ViTs and CNNs that takes the best of both for more performance and efficiency. ViTs split an image into patches and process them using transformer blocks, originally designed for language models. Hybrid models combine the **inductive bias** of CNNs with the **contextual power** of Transformers. The modular nature of hybrid models also enables researchers to experiment with different combinations of CNN and transformer components, leading to continuous innovations in architecture design. ViT-G is a next-generation, scaled-up version trained on a 3 billion image dataset for exploring large model scaling. For most practical applications, especially those with limited datasets or computational resources, CNNs or hybrid models often provide the best balance of performance and efficiency. Vision Transformers require substantial GPU power, CNNs run efficiently on modest hardware, and Hybrid models fall somewhere in between.
