aliran tensor:: operasi:: SparseSegmentSqrtNWithNumSegments
#include <math_ops.h> Menghitung jumlah sepanjang segmen tensor yang jarang dibagi dengan kuadrat N.
Ringkasan
N adalah ukuran segmen yang diperkecil.
Seperti SparseSegmentSqrtN , tetapi mengizinkan id yang hilang di segment_ids . Jika id tidak ada, tensor output pada posisi tersebut akan menjadi nol.
Baca bagian segmentasi untuk penjelasan segmen.
Argumen:
- ruang lingkup: Objek Lingkup
- indeks: Tensor 1-D. Memiliki peringkat yang sama dengan
segment_ids . - segment_ids: Tensor 1-D. Nilai harus diurutkan dan dapat diulang.
- num_segments: Harus sama dengan jumlah ID segmen yang berbeda.
Pengembalian:
-
Output : Bentuknya sama dengan data, kecuali dimensi 0 yang mempunyai ukuran k , jumlah segmen.
