Enes Causal Discovery
This work addresses causal discovery challenges in observational data, though it appears incremental in its approach.
The paper tackles causal discovery from observational data by proposing a mixture-of-experts architecture that parameterizes causal relationships, addressing data limitations that hindered previous approaches. The method achieves unspecified performance improvements over a strong baseline using Pearson coefficient linear models.
Enes The proposed architecture is a mixture of experts, which allows for the model entities, such as the causal relationships, to be further parameterized. More specifically, an attempt is made to exploit a neural net as implementing neurons poses a great challenge for this dataset. To explain, a simple and fast Pearson coefficient linear model usually achieves good scores. An aggressive baseline that requires a really good model to overcome that is. Moreover, there are major limitations when it comes to causal discovery of observational data. Unlike the sachs one did not use interventions but only prior knowledge; the most prohibiting limitation is that of the data which is addressed. Thereafter, the method and the model are described and after that the results are presented.
