Netwọk Capsule
Netwọk Capsule bụ ụlọ ọrụ akwara na-ekekọta neurons n'ime 'capsules' nke na-emepụta vectors na-edobe ma njirimara dị na ọnọdụ ya (ọnọdụ, nghazi, ọnụ ọgụgụ).
Nchịkọta
They aim to fix a core blindness in standard convolutional networks: losing track of spatial relationships between parts.

Ndị Geoffrey Hinton, Sara Sabour na Nicholas Frosst tụpụtara na 2017, netwọk capsule jiri vector dochie nsonaazụ neuron scalar. Ogologo vector na-anọchite anya ihe gbasara puru omume na ihe (dị ka anya ma ọ bụ imi) dị, ebe nghazi ya na-etinye akara ngosi. Capsules dị larịị na-ebu amụma maka ọnọdụ nke capsules dị elu site na mgbanwe matrices, na usoro a na-akpọ dynamic routing-by-agreement na-ekpebi amụma ndị a ga-atụkwasị obi. Mgbe ọtụtụ akụkụ-capsules kwekọrịtara n'otu ihe ahụ dum, ntụgharị na-ewusi njikọ ahụ ike. CapsNet izizi nwetara nsonaazụ siri ike na MNIST ma bụrụkwa nke siri ike na ọnụọgụ ọnụọgụ na mgbanwe affine, na-agwa 'nsogbu Picasso' ebe CNN na-anabata njiri ihu gbajiri agbaja dị ka ihu ziri ezi.

What is Capsule Networks?
Netwọk Capsule bụ ụlọ ọrụ akwara na-ekekọta neurons n'ime 'capsules' nke na-emepụta vectors na-edobe ma njirimara dị na ọnọdụ ya (ọnọdụ, nghazi, ọnụ ọgụgụ). Ha bu n'obi idozi isi kpuru isi na netwọkụ mmekọrịta ọkọlọtọ: na-efunahụ mmekọrịta gbasara oghere n'etiti akụkụ.
