Guaranteed Deterministic Bounds on the Total Variation Distance between Univariate Mixtures
arXiv
收藏 引用
arXiv 2018年
作者: Nielsen, Frank Sun, Ke Sony Computer Science Laboratories Inc. Japan Data61 Australia
The total variation distance is a core statistical distance between probability measures that satisfies the metric axioms, with value always falling in [0;1]. This distance plays a fundamental role in machine learning... 详细信息

arXiv 2022年
作者: Chijiwa, Daiki Yamaguchi, Shin'ya Kumagai, Atsutoshi Ida, Yasutoshi NTT Computer and Data Science Laboratories NTT Corporation Japan Kyoto University Japan
Few-shot learning for neural networks (NNs) is an important problem that aims to train NNs with a few data. The main challenge is how to avoid overfitting since over-parameterized NNs can easily overfit to such small ... 详细信息

arXiv 2018年
作者: Nielsen, Frank Sun, Ke Sony Computer Science Laboratories Inc. Japan Data61 Australia
We propose a new generic type of stochastic neurons, called q-neurons, that considers activation functions based on Jackson's q-derivatives, with stochastic parameters q. Our generalization of neural network archi... 详细信息
