TILES-2018 Evaluation Data Set Overview
The TILES-2018 Eval Data Set contains additional data for the TILES-2018 Main Data Set. This data set was collected at the same time and in the same manner as the main data set, but it was used as a holdout set for evaluating trained models for generalizability. In particular, this data set was collected over a 10-week period using the same sensors and setup as the main data with n=100 participants recruited not only from the USC Keck Hospital (like the main study) but also the USC Norris Comprehensive Cancer Center. Apart from the inclusion of hospital workers from the second site, the protocol was the same. You can learn more about the main study here.
We are releasing the eval data set one or a few modalities at a time, as we are able to clean and curate them for public use. Each available modality for the eval set can be downloaded alongside all modalities from the main data set from the TILES 2018 download page. The release of each eval data set modality will coincide with the publication of a paper describing the modality in more detail, comparing it to the main data set, and providing a baseline exploration of its predictive utility. The following modalities are currently available:
