∙ Universität Hildesheim ∙ 0 ∙ share . Machine learning tasks such as optimizing the hyper-parameters of a model for a new dataset or few-shot learning can be vastly accelerated if they are not done from scratch for every new dataset, but carry over findings from previous runs. The goal of meta-learning is to train a model on a variety of learning tasks, such that it can solve new learning tasks using only a small number of training samples. In our approach, the parameters of the model are explicitly trained such that a small number of gradient steps with a small amount of training data from a new task will produce good generalization performance on that task.

Motivated by use-cases in personalized federated learning, we study the often overlooked aspect of the modern meta-learning algorithms – their data efficiency. meta-learning involves learning how-to-learn and utilizing this knowledge to learn new tasks more effectively. This thesis focuses on using meta-learning to improve the data and processing efficiency of deep learning models when learning new tasks. First, we discuss a meta-learning model for the few-shot learning problem, where This thesis focuses on using meta-learning to improve the data and processing efficiency of deep learning models when learning new tasks. First, we discuss a meta-learning model for the few-shot learning problem, where the aim is to learn a new classification task having unseen classes with few labeled examples.

ASG 2019-05-19 · Meta-Learning takes advantage of the metadata like algorithm properties (performance measures and accuracy), or patterns previously derived from the data, to learn, select, alter or combine different learning algorithms to effectively solve a given learning problem. Meta Learning, an original concept of cognitive psychology, is now applied to machine learning techniques. If we go by the social psychology definition, meta learning is the state of being aware of and taking control of one’s own learning. Meta-learning makes use of features of a whole dataset such as its number of instances, its number of predictors, the means of the predictors etc., so called meta-features, dataset summary statistics or simply dataset characteristics, which so far have been hand-crafted, often specifically for the task at hand.
