Here, we focus on the dynamic aspect of this "curse of dimensionality" (COD) in continuous-time filtering, which is caused by the degeneracy of importance weights over time. We show that the degeneracy occurs on a time scale that decreases with increasing D. In order to soften the effects...
It is shown how this format can be applied to the problem of multidimensional convolution. Convincing numerical examples are given. 展开 关键词: Tree-Tucker Tucker decomposition canonical decomposition curse of dimensionality DOI: 10.1137/090748330 被引量: 417 ...
Machine Learning FAQ There are 3 main strategies to reduce the number of features if necessary to avoid overfitting (due to the curse of dimensionality) and/or reduce the computational complexity (i.e., increase the computational efficiency). 1) Regularization and Sparsity If supported by the mod...
Thecurse of dimensionalityusually refers to what happens when you add more and more variables to a multivariate model.The more dimensions you add to a data set, the more difficult it becomes to predict certain quantities.You would think that more is better. However, when it comes to adding v...
An important reason why I gave up with the shark attack dashboard – the data. Collecting, cleaning, maintaining, checking, updating the data is always a big chunk of any project. During regular work hours, you can spend enough time to make it right. And as any good data scientist knows...
