Utilities¶
Function utilities¶
Most of the feature transformation in nnmnkwii.preprocessing
module is 2d functions
f: (T, D) -> (T, D')
. The following utilities can be used for
extending 2d functions to 3d by applying 2d function to each 2d slice.
apply_each2d_padded (func2d, X, lengths, …) |
Apply function for each padded 2d slice. |
apply_each2d_trim (func2d, X, *args, **kwargs) |
Apply function for each trimmed 2d slice. |
Files¶
Part of files were taken from CMU ARCTIC dataset. Example quetsion file was taken from Merlin.
example_label_file ([phone_level]) |
Get path of example HTS-style full-context lable file. |
example_audio_file () |
Get path of audio file. |
example_question_file () |
Get path of example question file. |
example_file_data_sources_for_duration_model () |
Get file data sources for duration model training. |
example_file_data_sources_for_acoustic_model () |
Get file data sources for acoustic model training |
Linear algebra¶
cholesky_inv (L[, lower]) |
Compute inverse matrix of real symmetric positive definite matrix using choleskey factorization. |
cholesky_inv_banded (L[, width]) |
