Adaptive sampling for active learning with genetic programming

WebA Bayesian model of learning to learn by sampling from multiple tasks is presented. The multiple tasks are themselves generated by sampling from a distribution over an environment of related tasks. Such an environment is shown to be naturally modelled within a Bayesian context by the concept of an objective prior distribution. It is argued that for … Web25 de fev. de 2024 · Active learning (AL) has widely been used to address the shortage of labeled datasets. Yet, most AL techniques require an initial set of labeled data as the knowledge base to perform active querying. The informativeness of the initial labeled set significantly affects the subsequent active query; hence the performance of active … flare over the pits
