摘要:Abstract(#br)In this paper, a scheme of probabilistic 3D object recognition from 2D view sequence is presented. For the tradeoff between information simplicity and sufficiency, based on similarity measure, proper invariant characteristic set is first acquired in a model view lear...

摘要:We put forward a quick clustering method for large numbers of data, with high dimensions, which is based on sensitive subspace consisting of the data set's sensitive dimensions. We first estimate the probability density of each dimension by the parzen window algorithm, enhance it...

摘要:In deep learning scenarios, a lot of labeled samples are needed to train the models. However, in practical application fields, since the objects to be recognized are complex and non-uniformly distributed, it is difficult to get enough labeled samples at one time. Active learning ...
