Project Background:
Online meta-learning addresses the challenges posed by the dynamic and evolving nature of data streams in machine-learning tasks. Traditional machine learning approaches often assume static datasets where the entire dataset is available from the beginning of the training process. However, data arrives continuously streaming, and the underlying data distribution may change over time. It aims to adapt traditional meta-learning techniques to handle such dynamic environments by continuously learning from incoming data streams and updating model parameters accordingly.
This project involves recognizing the limitations of existing meta-learning approaches in handling online learning tasks and developing new algorithms and methodologies that can efficiently adapt to changing data distributions and evolving task requirements. By leveraging insights from both online learning and meta-learning, the project aims to develop scalable and robust online meta-learning frameworks capable of effectively adapting to new tasks, environments, and data streams in real-time.
Additionally, this may involve exploring theoretical foundations, algorithmic frameworks, and practical applications of online meta-learning in various domains, including online recommendation systems, adaptive optimization, and continual learning scenarios. Overall, the project sets the stage for developing innovative approaches to online meta-learning that can effectively tackle the challenges posed by dynamic and evolving data streams in machine-learning tasks.
