CalculateDiffs ( PivotTableEntry a, PivotTableEntry b ) : Double>.Dictionary |
Calculates the difference between the values in entry a and b. The resulting distribution is normalized to a value between 0 and 1 |
|
|
DetectChange ( PivotTable ptA, PivotTable ptB, string label, bool diffs ) : PivotTable |
Compares two pivot tables. Do not pass in columns that don't make sense to compare. This method encapsulates a cosine similarity calculation on geohash cell pairs, and subsequently, each pair also calculates a diff between each col pair as a quasi percentage diff. |
|
|
FileToPivotTable ( String file, string rowkeyColumnName ) : PivotTable |
Converts a csv file to a pivot table. |
|
|
GenerateAverageVector ( PivotTable tableWithMoreThanOneRow ) : PivotTable |
|
|
|
GetSimilarityGraph ( PivotTable signature ) : Dictionary> |
|
|
|
GetSparseSimilarites ( PivotTableEntry baseVector, PivotTable vectors, bool logarithm, bool onlyBase ) : PivotTable |
|
|
|
GetSparseSimilarity ( PivotTableEntry a, PivotTableEntry b, bool logarithm, bool onlyBase ) : PivotTableAnalysisResult |
Returns a PivotTableAnalysisResult with an empty Data dictionary but with a prob score set to the cosine similarity value of the two input vector spaces. Look here for more info: https://upload.wikimedia.org/math/4/e/4/4e45dc7ae582130813e804f793f24ead.png |
