navis.nbl.smat.Lookup2d¶

class navis.nbl.smat.Lookup2d(axis0, axis1, cells)[source]¶

Convenience class inheriting from LookupNd for the common 2D float case. Provides IO with pandas DataFrames.

2D lookup table for convert NBLAST matches to scores.

Commonly read from a pandas.DataFrame or trained on data using a LookupDistDotBuilder.

Parameters:

digitizer0 (Digitizer) – How to convert continuous values into an index for the first axis.
digitizer1 (Digitizer) – How to convert continuous values into an index for the second axis.
cells (np.ndarray) – Values to look up in the table.

__init__(axis0, axis1, cells)[source]¶

2D lookup table for convert NBLAST matches to scores.

Commonly read from a pandas.DataFrame or trained on data using a LookupDistDotBuilder.

Parameters:

digitizer0 (Digitizer) – How to convert continuous values into an index for the first axis.
digitizer1 (Digitizer) – How to convert continuous values into an index for the second axis.
cells (np.ndarray) – Values to look up in the table.

Methods

`__init__`(axis0, axis1, cells)	2D lookup table for convert NBLAST matches to scores.
`from_dataframe`(df)
`to_dataframe`()	Convert the lookup table into a `pandas.DataFrame`.
