Siv LSTMs los kwv yees sij hawm - series . RNN cov ( LSTM cov ) zoo nkauj zoo ntawm extracting qauv nyob rau hauv input feature qhov chaw, qhov twg cov ntaub ntawv input spans ntev sequences. Muab lub gated architecture ntawm LSTM cov uas muaj peev xwm los tswj nws lub xeev nco, lawv zoo tagnrho rau cov teeb meem zoo li no.

Ib yam li ntawd, tib neeg nug, Lstm lub sijhawm series yog dab tsi?

LSTM (Long Short-Term Memory network) yog ib hom kev rov muaj dua neural network muaj peev xwm nco qab cov ntaub ntawv yav dhau los thiab thaum kwv yees cov txiaj ntsig yav tom ntej, nws yuav siv cov ntaub ntawv yav dhau los no rau hauv tus account. Txaus ntawm qhov preliminaries, cia saib yuav ua li cas LSTM tuaj yeem siv rau sij hawm series tsom xam.

Tom qab, lo lus nug yog, Lstm zoo rau dab tsi? Long-term nco ( LSTM ) yog ib qho khoom siv rov ua dua tshiab neural network ( RNN ) architecture siv hauv kev kawm tob. LSTM cov tes hauj lwm zoo tsim nyog rau kev faib tawm, ua tiav thiab ua kev kwv yees raws li cov ntaub ntawv teev sijhawm, vim tias muaj peev xwm ua rau tsis paub ntev ntawm cov xwm txheej tseem ceeb hauv ib lub sijhawm.

Ntawm no, Lstm puas zoo dua Arima?

ARIMA tawm los zoo dua ua rau forecasting lub sij hawm luv, whereas LSTM tawm los zoo dua cov txiaj ntsig rau kev ua qauv ntev. Tus naj npawb ntawm cov sij hawm kawm, hu ua "epoch" hauv kev kawm tob, tsis muaj kev cuam tshuam rau kev ua tau zoo ntawm cov qauv kev kwv yees thiab nws nthuav tawm tus cwj pwm tsis zoo.

Lstm kwv yees li cas?

Ib qhov kawg LSTM qauv yog ib qho uas koj siv los ua kwv yees ntawm cov ntaub ntawv tshiab. Ntawd yog, muab piv txwv tshiab ntawm cov ntaub ntawv nkag, koj xav siv tus qauv rau kwv yees qhov kev cia siab tso zis. Qhov no tej zaum yuav yog ib qho kev faib (muab daim ntawv lo) los yog regression (tus nqi tiag).
