Pattern Recognition Approach
[Copy link]

haiii.....
mari2 kongsi idea sama aku....ader sape2 yg arif pasai pattern recognition approach ni tak?
yg aku tau benda ni digunakan utk data identification...so kita leh tau distribution data tu, trend dia...and yg aku tau ni adalah satu lagi approach utk lihat seasonality utk data tu selain guna ACF/PACF....Sarah ader idea tak? kalu U pernah ler dengar2 atau baca artikel ttg ni...leh la kongsi ngan aku yek...and for others yg pernah lihat atau dengar atau baca...pun sudi2lah lah kongsi ngan aku....Thankksss |

pattern recog .. nope .. tak pandai .. tapi 2 of my junior buat benda ni kalau tak silap..
sorang masuk forum ni .. nanti i inform dia biler i nampak dia online.. ;) |

Ini dia junior sarah mai dahhh :jeler:
from ap yg aku paham la so far ...
Pattern recognition --> research area that studies the operation and design of systems that recognize patterns in data.
subdisciplines: discriminant analysis, feature extraction, error estimation, cluster analysis (together sometimes called statistical pattern recognition), grammatical inference and parsing (sometimes called syntactical pattern recognition).
Some application areas: image analysis, character recognition, speech analysis, man and machine diagnostics, person identification and industrial inspection.
...
ACF/PACF ni mende plak? |

Thankss mentos...
aku nak guna pattern recognition ni utk apply dlm time series...aku nak detect data aku tu ader seasonality tak....sbb yg sblm ni aku buat kena plot ACF/PACf dulu pastu based on that graph baru aku tau ader baper dia nyer seasonality....
aku sbnarnyer..mmg tak braper tau sgt pasai nih...sbb baru nak explore...
emmm...korang ni U mana yek...:hmm:.... |

ohhh...gitu ke? seasonality mcmn nak detect tu? explain sket.. |
|
|
|
|
|
|

okey camnie...data yg aku guna ni...data univariate...time series data...
nak detect seasonality nih mula2:
kita plot data dulu...pastu klu kita nampak cam ader naik turun dlm graph tu...maybe ader seasonality....
cthnyer...
kita amik data sales (sales on ayam katerkan)
masa perayaan mesti jumlah sales tu meningkat....bila hari biasa jd normal je...so...ader seasonality effect kat situ...klu plot graph...dlm bulan nov-jan naik...pastu feb-mac...biasa...seterusnya...
so...klu data tu mmg kita dah tau bila peak bila idak...senang skit...tp klu data tu jap length 3 jap g berubah lak...susah nak detect ngan mata kasar...klu kita plot ACF ngan PACF pun susah nak tentukan AR(?) ngan MA(?) camtu gak ngan seasonality tu baper....
sbb2 nak detect seasonality ni...kita nak buang effect seasonality nih...utk develop model yg sesuai bg data tuh...jd...klu kita guna pattern recognition nih kita leh amik value dia...jdkan input...
emm...ko ader tak artikel2 pasai pattern recognition yg diapply untuk forecasting....klu ader nak leh...
ok dak aku nyer explanation....klu tak paham leh aku explain lagik...
emm...setakat nih ko apply pattern recognition nih utk apa? leh citer cara ko apply tu...TQ :love: |

ohhh.. paham.. paham ...
hmm ..aku guna pattern recog ni utk image analysis .. like edge detection etc utk object recognition ..
kalau case kau ni ... hmm, takde pulak aku jumpa article so far .. but maybe ada satu ni kot (aku email kau la) .. itu pun brief exp. takde detail sangat.. tapi kalau tak salah aku la.. utk forecasting masuk category statistical pattern recog...
emm ... bak sini email ko ..

Thankssss...agian mentos
aku dah baca dah...kira dapat ler skit overview ttg Pattern recognition nih....
aku rasa cam bos aku nak suruh wat je...sbb senang nak detect pattern...tapi susah nak develop...
TQ |
|
|
|

no probs..
kalau nak senang develop, ko program guna matlab la.. |
|

Thanksss...mentos...skang ni aku tgh dok usha2 lagi paper ttg pattern recognition ni...mgkn next project baru buat kot...skang ni dok wat review lagik...nanti klu aku dah dpt apply kat forecasting side aku bg tau yek....
makacih :love: |

Pattern recognition biasannya banyak digunakan dalam Artificial Intelligent, Neural Network (Artificial), Computational Intelligence... Dalam masalah harian kita juga banyak menggunakan pattern recognition,... contohnya dalam aplikasi cap jari kita scan pattern yang ada pada cap jari.. wang.. nak sahkan sama ada wang itu palsu atau p[un ori |

Thanks...for the info
aku ader baca gak ttg semua tu...tapi skang ni nak apply dlm forecasting...emmm....malehnyerrrr.....nak baca teori...hehhehehe...tapi nak wat camner...kena cari gak...klu ader ler terbaca artikel apa2 ttg pattern recognition approach in forecasting bg kat aku yek...makacehhh byk2.... |

A'kom,
saya rasa-rasa lah, kalau tak nak hiraukan pattern seasonal tu, mentari kena pilih algorithm yg bersesuaian. ATAU, lakukan feature extraction? kena proses data-data tu dulu. google byk reference pasal feature extraction ni. Dah decide algorithm yg nak dipilih nanti, tanya lah lagi.
OK! |

aku ada belajr pattern recognition....
fingerprint manusia senua tidak sanma.... jadi setiap fingerprint ada pattern tersendiri ada gelung....... pattern recognition kalau gabong dengan neural network sistem yang direka boleh jadi yang terbaik |
