Optimality of Thompson Sampling for Gaussian Bandits Depends on Priors
Junya Honda, Akimichi Takemura
In stochastic bandit problems, a Bayesian policy called Thompson sampling (TS) has recently attracted much attention for its excellent empirical performance. However, the theoretic…
Exact MIMO Zero-Forcing Detection Analysis for Transmit-Correlated Rician Fading
Constantin Siriteanu, Steven Blostein, Akimichi Takemura +3
We analyze the performance of multiple input/multiple output (MIMO) communications systems employing spatial multiplexing and zero-forcing detection (ZF). The distribution of the Z…
Markov degree of the Birkhoff model
Takashi Yamaguchi, Mitsunori Ogawa, Akimichi Takemura
We prove the conjecture by Diaconis and Eriksson (2006) that the Markov degree of the Birkhoff model is three. In fact, we prove the conjecture in a generalization of the Birkhoff…
