tensoreflusso:: ops:: Media dei segmenti sparsi
#include <math_ops.h> Calcola la media lungo segmenti sparsi di un tensore.
Riepilogo
Vedi tf.sparse.segment_sum per esempi di utilizzo.
Come SegmentMean , ma segment_ids può avere un rango inferiore alla prima dimensione data , selezionando un sottoinsieme della dimensione 0, specificato da indices .
Argomenti:
- scope: un oggetto Scope
- indici: un tensore 1-D. Ha lo stesso rango di
segment_ids . - segment_ids: un tensore 1-D. I valori devono essere ordinati e possono essere ripetuti.
Resi:
-
Output : ha la stessa forma dei dati, ad eccezione della dimensione 0 che ha dimensione k , il numero di segmenti.
