Hierarchical sampling for active learning

WebHoje · Unlike settings of prior studies, 8 sophisticated deep-learning methods substantially outperform simplistic approaches, with our top-performing model combining cutting-edge techniques such as transformers, 3 domain-specific pretraining, 7 recurrent neural networks, 11 and hierarchical attention. 12 Our method naturally handles longitudinal information, … 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 …

A good learning objective should be independent of the scale changes of the target loss. They instead rely on the comparison of sample pairs.

Web12 de abr. de 2024 · Active restoration involves sowing seeds or planting seedlings, followed by post-planting management (Aavik et al., 2013; Chang et al., 2024; Sujii et al., 2024). The level of GD in populations that recover through active restoration largely depends on human efforts, such as sampling strategies for the seed sources. Web19 de jul. de 2024 · For active learning with missing values, query selection is generally performed after all missing values are imputed.
