Project Background:
Deep ensemble learning is an approach within machine learning that focuses on combining predictions from multiple deep neural networks to enhance model robustness and performance. This technique is particularly valuable when dealing with complex tasks such as image classification, natural language processing, and anomaly detection. This typically outlines the challenges of single deep models, which can mostly suffer from overfitting, instability, and generalization issues. A proven track record of improving model accuracy is realized by building on the concept of ensembles. Deep ensemble learning aims to mitigate problems. Therefore, this model may touch upon the historical development of ensemble methods to adapt the unique characteristics of deep neural networks.
Problem Statement
- The context of deep ensemble learning primarily addresses challenges associated with single deep neural networks. Deep neural networks have shown remarkable capabilities in various machine learning tasks and often suffer from issues like limited generalization to diverse data distributions.
- The problem at hand is to enhance the robustness, reliability, and overall performance of the deep models. Deep ensemble learning seeks to tackle this problem by combining predictions from multiple deep networks, each with different architectures trained on numerous data subsets.
