Acestor Documentation

Acestor is a production dengue intelligence pipeline. It ingests case and weather data, estimates risk thresholds, runs forecasting models, produces choropleth maps, and generates automated report artifacts — all driven from a single YAML configuration file.

Pipeline Stages

The pipeline is a 14-step DAG — steps run concurrently where dependencies allow.

#	Step	What it does
1	identify_sampling_day	Resolves the run date and case sampling window
2	download_case_data	Fetches or copies raw case inputs (filesystem or S3)
3	download_weather_data	Fetches weather data from CDS API or local cache
4	parse_case_data	Parses linelist → daily case series by region
5	validate_case_data_sufficiency	Early gate — stops if data is too thin to model
6	parse_weather_data	Aggregates ERA5 weather features aligned to regions
7	identify_cutoff_dates	Computes case/weather cutoffs and prediction calendar
8	generate_thresholds	Builds per-region threshold tables from historical data
9	train_and_predict	Fits NBR and TSE models, writes predictions
10	combine_predictions	Merges region predictions into a single table
11	assess_thresholds	Threshold assessment and figure metadata
12	generate_maps	Produces choropleth map PNGs
13	generate_report	Bundles JSON metadata, LaTeX source, and maps zip
14	notify_run	Sends success/failure email (if configured)
