Supervised deep learning has achieved remarkable success in various applications. Such advances were mainly attributed to the rise of computational powers and the amounts of training data made available. Therefore, accurate large-scale data collection services are often needed. One representative data is retrieved, it becomes possible to train the supervised machine learning predictor. However, a model trained on existing data, which generally comes from multiple datasets, might generalize poorly on the unseen target data. This problem is referred to as a domain shift. In this paper, we explore the suitability of data selection to tackle the domain shift challenge in the context of domain generalization. We perform our experimental study on the use case of building energy consumption prediction. Experimental results suggest that minimal building description is capable of improving cross-building generalization performances when used to select data.
