Web2.2 Meta-learning Meta-learning is a “learning to learn” method, in which a learner learns new tasks and another meta-learner learns to train the learner (Bengio et al., … WebMeta learners are a simple way to leverage off-the-shelf predictive machine learning methods in order to solve the same problem we’ve been looking at so far: estimating the …
Meta-learners for Estimating Heterogeneous Treatment E …
WebI then trained a single (RandomForest) model on the outputs of those 15 (the probability outputs, not hard predictions). The results were surprising to me: The meta learner (single 2nd level RF model) did not do any better than the average individual "base" learner result. In fact, there were some base level models that did better than the meta ... Web28 mrt. 2024 · X-learner is a meta-learner that is an extension of the T-learner. Compared with T-learner, X-learner is better for highly imbalanced treatment and control groups. pascal trauffler

Web18 dec. 2024 · metalearners with other base learners can significantly outper-form causal forests. The main contribution of this work is the introduction of a metaalgorithm: the X-learner, which builds on the T-learner and uses each observation in the training set in an “X”-like shape. Suppose that we could observe the individual treatment effects Web19 nov. 2024 · X-Learner Uplift Model in Python Manually create meta-learner X-learner: Model data processing, model training, prediction, individual treatment effect (ITE) and average treatment effect... pascal traveling clamp
