Deep Neural Networks (DNNs) have demonstrated remarkable success across various domains, yet they often require large datasets and significant computational resources to achieve optimal performance. Transfer learning, a powerful technique that leverages pre-trained models, offers an efficient solution to these limitations by enabling knowledge transfer from one task to another. This paper introduces novel concepts in integrating transfer learning with DNNs, focusing on reducing model complexity, improving generalization, and addressing the challenges of domain adaptation. A hybrid architecture is proposed that combines task-specific fine-tuning with meta-learning to enhance model flexibility across diverse applications. The architecture is evaluated using the ImageNet dataset for image classification tasks, where an adaptive transfer learning framework dynamically selects and fine-tunes pre-trained models based on the similarity between source and target domains. This approach significantly reduces the risk of negative transfer, outperforming traditional transfer learning techniques in terms of accuracy, convergence speed, and resource efficiency. Additionally, unsupervised and selfsupervised learning techniques are incorporated to maximize the utility of unlabelled data in transfer learning workflows. The proposed method is also validated on the CIFAR-10 dataset, demonstrating superior performance in terms of generalization and efficiency. Potential applications in real-world scenarios, such as autonomous systems and healthcare image analysis, are discussed. This research work contributes to advancing DNNs by providing innovative frameworks that push the boundaries of transfer learning, delivering robust, scalable, and efficient solutions for complex tasks.
