Clustering by latent dimensions
Shohei Hidaka, Neeraj Kashyap
This paper introduces a new clustering technique, called {\em dimensional clustering}, which clusters each data point by its latent {\em pointwise dimension}, which is a measure of…
Polynomial algorithm for -partition minimization of monotone submodular function
Shohei Hidaka
For a fixed , this study considers -partition minimization of submodular system with a finite set and symmetric submodular function …
Fast and exact search for the partition with minimal information loss
Shohei Hidaka, Masafumi Oizumi
In analysis of multi-component complex systems, such as neural systems, identifying groups of units that share similar functionality will aid understanding of the underlying struct…
Recursive Markov Process for Iterated Games with Markov Strategies
Shohei Hidaka
The dynamics in games involving multiple players, who adaptively learn from their past experience, is not yet well understood. We analyzed a class of stochastic games with Markov s…
On the Estimation of Pointwise Dimension
Shohei Hidaka, Neeraj Kashyap
Our goal in this paper is to develop an effective estimator of fractal dimension. We survey existing ideas in dimension estimation, with a focus on the currently popular method of…
General Type Token Distribution
Shohei Hidaka
We consider the problem of estimating the number of types in a corpus using the number of types observed in a sample of tokens from that corpus. We derive exact and asymptotic dist…
