Short-Term Wind-Speed Forecasting Using Kernel Spectral Hidden Markov Models

no code implementations15 Nov 2018 Shunsuke Tsuzuki, Yu Nishiyama

In machine learning, a nonparametric forecasting algorithm for time series data has been proposed, called the kernel spectral hidden Markov model (KSHMM).

Model-based Kernel Sum Rule: Kernel Bayesian Inference with Probabilistic Models

no code implementations18 Sep 2014 Yu Nishiyama, Motonobu Kanagawa, Arthur Gretton, Kenji Fukumizu

Our contribution in this paper is to introduce a novel approach, termed the {\em model-based kernel sum rule} (Mb-KSR), to combine a probabilistic model and kernel Bayesian inference.

Characteristic Kernels and Infinitely Divisible Distributions

no code implementations28 Mar 2014 Yu Nishiyama, Kenji Fukumizu

If $P, Q$, and kernel $k$ are Gaussians, then computation (i) and (ii) results in Gaussian pdfs that is tractable.

Filtering with State-Observation Examples via Kernel Monte Carlo Filter

no code implementations17 Dec 2013 Motonobu Kanagawa, Yu Nishiyama, Arthur Gretton, Kenji Fukumizu

In particular, the sampling and resampling procedures are novel in being expressed using kernel mean embeddings, so we theoretically analyze their behaviors.
