-# MEDS_Tabular_AutoML
-Limited automatic tabular ML pipelines for generic MEDS datasets.
+# Scalable tabularization and tabular feature usage utilities over generic MEDS datasets
+This repository provides utilities and scripts to run limited automatic tabular ML pipelines for generic MEDS
+datasets.
+
+Why not other systems?
+  - [TemporAI](https://github.com/vanderschaarlab/temporai) is the most natural competitor, and already
+    supports AutoML capabilities. However, TemporAI (as of now) does not support generic MEDS datasets, and it
+    is not clear if their AutoML systems will scale to the size of datasets we need to support. But, further
+    investigation is needed, and it may be the case that the best solution here is simply to write a custom
+    data source for MEDS data within TemporAI and leverage their tools.
+
+# Installation
+Clone this repository and install the requirements by running `pip install .` in the root directory.
+
+# Usage
+This repository consists of two key pieces:
+  1. Construction of and efficient loading of tabular (flat, non-longitudinal) summary features describing
+     patient records in MEDS over arbitrary time-windows (e.g. 1 year, 6 months, etc.) either backwards or
+     forwards in time from a given index date. Naturally, only "look-back" windows should be used for
+     future-event prediction tasks; however, the capability to summarize "look-ahead" windows is also useful
+     for characterizing and describing the differences between patient populations statistically.
+  2. Running basic AutoML pipelines over these tabular features to predict arbitrary binary classification
+     downstream tasks defined over these datasets. The "AutoML" part of this is not particularly advanced --
+     what is more advanced is the efficient construction, storage, and loading of tabular features for the
+     candidate AutoML models, enabling a far more extensive search over different featurization strategies.
+
+## Feature Construction, Storage, and Loading
+
+## AutoML Pipelines
+
+# TODOs
+  1. Leverage the "event bound aggregation" capabilities of [ESGPT Task
+     Select](https://github.com/justin13601/ESGPTTaskQuerying/) to construct tabular summary features for
+     event-bound historical windows (e.g., until the prior admission, until the last diagnosis of some type,
+     etc.).
+  2. Support more feature aggregation functions.
+  3. Probably rename this repository, as the focus is really more on the tabularization and feature usage
+     utilities than on the AutoML pipelines themselves.
+  4. Import, rather than reimplement, the mapper utilities from the MEDS preprocessing repository.
+  5. Investigate the feasibility of using TemporAI for this task.
+  6. Consider splitting the feature construction and AutoML pipeline parts of this repository into separate
+     repositories.
