LSTMs daws qhov teeb meem uas siv cov qauv gradient tshwj xeeb ntxiv uas suav nrog ncaj qha nkag mus rau lub qhov rooj tsis nco qab qhov kev ua haujlwm, ua rau lub network txhawb kev xav tau tus cwj pwm los ntawm qhov yuam kev gradient siv lub rooj vag hloov tshiab. ntawm txhua lub sijhawm ntawm cov txheej txheem kev kawm.

LSTM daws qhov tawg ntawm gradient li cas?

A lus teb luv luv: LSTM decouples cell xeev (feem ntau denoted los ntawm c) thiab zais txheej / tso zis (feem ntau denoted los ntawm h), thiab tsuas yog ua additive tshiab rau c, uas ua rau nco nyob rau hauv c ntau ruaj khov. Yog li gradient ntws los ntawm c tau khaws cia thiab nyuaj rau ploj mus (yog li tag nrho cov gradient nyuaj ploj mus).

Yuav daws qhov teeb meem gradient ploj mus li cas?

Cov kev daws teeb meem: Cov kev daws teeb meem yooj yim tshaj plaws yog siv lwm yam ua kom ua haujlwm, xws li ReLU, uas tsis ua rau me me derivative. Residual networks yog lwm txoj kev daws teeb meem, raws li lawv muab cov seem txuas ncaj qha rau cov txheej txheem ua ntej.

LSTM daws teeb meem dab tsi?

LSTMs. LSTM (luv luv rau lub sij hawm luv luv) feem ntau daws tau qhov teeb meem ploj mus hauv kev rov qab. LSTMs siv lub rooj vag mechanism uas tswj cov txheej txheem memoizing. Cov ntaub ntawv hauv LSTMs tuaj yeem khaws cia, sau, lossis nyeem ntawm cov rooj vag uas qhib thiab kaw.

Vim li cas LSTMs nres koj cov gradients los ntawm kev ploj mus los ntawm kev hla rov qab?

Qhov laj thawj ntawm qhov no yog vim tias txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau qhov yuam kev tsis tu ncua, kev ntsuas gradient raug txiav kom tsis txhob ntws rov qab mus rau cov lus nkag lossis cov rooj sib tw.
