Software monad for Geometric Nearest Neighbors workflows
Contributed by: Anton Antonov
Software monad for Geometric Nearest Neighbors (GNN) workflows: data rescaling, fast anomalies finding, similarity matrices derivation.
Installation Instructions
To install this paclet in your Wolfram Language environment,
evaluate this code:
PacletInstall["AntonAntonov/MonadicGeometricNearestNeighbors"]
To load the code after installation, evaluate this code:
Needs["AntonAntonov`MonadicGeometricNearestNeighbors`"]
Details
The Geometric Nearest Neighbors Monad (GNNMon) has a fast anomalies finding algorithm based on nearest neighbor functions and 1D outlier finding.
GNNMon uses Nearest and the 1D outlier identifiers in the paclet "AntonAntonov/OutlierIdentifiers".

Basic Examples (3)
Here is a dataset of random points:
| In[1]:= | ![SeedRandom[2323];
dsPoints = ResourceFunction["RandomTabularDataset"][{30, {"X", "Y"}}, "Generators" -> <|1 -> NormalDistribution[0, 5], 2 -> NormalDistribution[12, 3]|>, "RowKeys" -> True];
dsPoints[[1 ;; 4]]](https://www.wolframcloud.com/obj/resourcesystem/images/726/726c8ee3-1a97-4978-8ed3-a2ed51a35349/1-0-1/781e95033fa5ca26.png) |
| Out[3]= |  |
Here is a summary and a plot:
| In[4]:= | ![Row[{Labeled[ResourceFunction["RecordsSummary"][dsPoints], "Data summary", Top], Spacer[5], ListPlot[dsPoints[Values, Values], PlotTheme -> "Detailed", PlotLabel -> "Data points", ImageSize -> Medium]}]](https://www.wolframcloud.com/obj/resourcesystem/images/726/726c8ee3-1a97-4978-8ed3-a2ed51a35349/1-0-1/4c7b52005089a56f.png) |
| Out[4]= |  |
Here is a monadic Geometric Nearest Neighbors Monad (GNNMon) pipeline for finding outliers:
| In[5]:= | ![(* Evaluate this cell to get the example input *) CloudGet["https://www.wolframcloud.com/obj/8770af02-eda7-4c35-ad73-5d79adad8ae4"]](https://www.wolframcloud.com/obj/resourcesystem/images/726/726c8ee3-1a97-4978-8ed3-a2ed51a35349/1-0-1/49164a2c4af23149.png) |
