Applying causal inference models in areas such as economics, healthcare and marketing receives great interest from the machine learning community. In particular, estimating the individual-treatment-effect (ITE) in settings such as precision medicine and targeted advertising has peaked application. Optimising the ITE under the strong ignoreability assumption — meaning all confounders expressing influence on the outcome of a treatment are registered in the data — is often referred to as uplift modeling (UM).
While these techniques have proven useful in many settings, they suffer vividly in a dynamic environment due to concept drift. Take for example the negative influence on a marketing campaign when a competitor product is released. To counter this, we propose the uplifted contextual multi-armed bandit (U-CMAB), a novel approach to solve the UM problem by drawing upon bandit literature. Simulations indicate that our proposed approach significantly outperforms the state-of-the-art. As this research is still ongoing, we present only preliminary results in this extended abstract.
