The diverse contributions of the different regions of the smartphone behavioral space to the model output

Contributions were estimated using the gradient ∗ input method (see [Ancona et al., 2018]) to reveal the parts of the behavioral space that contributed to the rise in the model output (in red) and fall of the output (in blue).

(A) The average contributions across the 9 hours bins used as input for the feature space consisting of all inter-touch intervals (see also Figure S9).

(B) Same as (A) but for the feature space consisting of inter-touch intervals on social apps.
