There is a growing interest in estimating heterogeneous treatment effects across individuals using their high-dimensional feature attributes.

We propose a Bayesian inference framework that quantifies the uncertainty in treatment effect estimation to support decision-making in a relatively small sample size setting.

With our formulation, we can obtain optimal task-specific parameters in a closed form that are differentiable with respect to task-shared parameters, making it possible to perform effective meta-learning.

Finding the features relevant to the difference in treatment effects is essential to unveil the underlying causal mechanisms.

To avoid restrictive functional assumptions, we define the {\it probability of individual unfairness} (PIU) and solve an optimization problem where PIU's upper bound, which can be estimated from data, is controlled to be close to zero.
