This repository collects all source code and documentation of the fatalities model used by the Violence & Impacts Early-Warning System (VIEWS) to predict the number of fatalities in impending conflict.
The Documentation folder documents the models that inform the VIEWS forecasts.
Ensemble_{type of violence} files provides an overview of the sub-models that inform the concerned ensemble models. They list the so-called feature- or querysets and the algorithms that inform each sub-model, a short descriptions of the sub-models, and the dependent/outcome variables for which the sub-models are trained to generate predictions.Model_ files, in turn, document the data variables that feed into each of the aforementioned feature- or querysets, i.e. the groups of related input variables that inform the sub-models.Model column specifies the concerned feature- or queryset. For clarity, it also contains a reference to the model ensemble for which it was created. Taken together, each entry is constructed as {model name}{model version}_{queryset name}.Database variable name is constructed as {table in the VIEWS3 database}.{raw data variable}, where the latter refers to the raw data ingested from a given data provider, aggregated to the VIEWS levels of analysis where needed.Transformations lists the transformation we apply to the raw data in the next step of our data processing. This includes filling in for missing data, adding log transformations, temporal decays, time- and space lags to capture effects on neighbouring areas, and so forth. To learn more about our transform operations, please see the VIEWS Transformations Library.Included variable name lists the processed variables that ultimately inform our prediction models, generated by applying the listed transformations to the corresponding raw data variables.The Intermediates folder is a storage space for rarely-updated files containing, e.g., genetic weights used in computing the ensembles and json files used in codebooks published on the API'.
MonthlyUpdates contain the high-level code required to produce the monthly updates of the VIEWS forecasts (the cm_futurepredictions and pgm_futurepredictions notebooks). It also contains a set of Jupyter notebooks that allow users to explore, visualize, and download data from the VIEWS database, such as our monthly prediction datasets, or sub-sets of input data.
SystemUpdates contain the high-level code required to train and evaluate our models.
Tools contains low-level code for defining ensembles, constituent models, and the querysets they rely upon, for import into the high-level notebooks.
