Shapley additive explanations for NO2 forecasting

Abstract

In this paper, we address the problem of the interpretability of a machine learning model designed to predict air quality time series. When constructing a forecasting model, in addition to obtaining good accuracy, it is utterly important to understand why each prediction is made. Usually, interpreting the output of machine learning models is considered to be very difficult due to their complex “black box” architecture. However, we show how Shapley additive explanations can be used to interpret the outputs of a deep neural network designed to predict Nitrogen dioxide concentrations in Madrid. This method computes an estimation of the contribution of each feature for a particular prediction. Furthermore, we compare three explanatory methods to determine which one is more suitable for the air quality data and for the chosen machine learning model. A deeper insight into how the model behaves when predicting the pollution time series is obtained.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
