Efficient Transfer Bayesian Optimization with Auxiliary Information

Tomoharu Iwata, Takuma Otsuka

We propose an efficient transfer Bayesian optimization method, which finds the maximum of an expensive-to-evaluate black-box function by using data on related optimization tasks. O…

Multi-output Polynomial Networks and Factorization Machines

Mathieu Blondel, Vlad Niculae, Takuma Otsuka +1

Factorization machines and polynomial networks are supervised polynomial models based on an efficient low-rank decomposition. We extend these models to the multi-output setting, i.…
