Poster #67 A black-box model + High predictive performance - non-interpretable An interpretable model A hybrid of both? + interpretable - lower predictive performance
Poster #67 A black-box model + High predictive performance - non-interpretable An interpretable model A hybrid of both? + interpretable - lower predictive performance A key observation: there might exist a subspace where a black-box is overkill and a simple interpretable model can perform just as well as the black-box
Poster #67 A black-box model An interpretable model A hybrid of both? + High predictive performance An effective trade-off + interpretable A key observation: there might exist a subspace where a black-box is overkill and a simple interpretable model can perform just as well as the black-box The proposed solution: to substitute the black-box model with an interpretable model, where there is no or low- cost of predictive performance
