  4. Pengenalan • Tujuan • Takrifan perlombongan data • Perkembangan perlombongan data sehingga kini • Permasalahan • Arah tuju penyelidikan IRPA 04-02-02-0004 EA004

  5. Proses perlombongan data 1 Visualisasi Perlombongan Data Transformasi & Reduksi Corak / model Pemprosesan & pembersihan Data terjelma Rahsia Kesan Jangkaan Tindakan Pensampelan & Pemilihan Data bersih Data sasaran Berpandukan Fayad 1996 IRPA 04-02-02-0004 EA004

  6. Takrifan Perlombongan Data • Grabmeier et al 2001 • ..is the notion of all methods and techniques, which allow to analyse very large data sets to extract and discover previously unknown structures and relations out of such huge heaps of details. These information is filtered, prepared and classified so that it will be a valuable aid for decisions and strategies. • Witten 2000 • ‘Data mining is about solving problems by analyzing data already present in databases’ • Fayad et al 1994 • KDD means a nontrivial process of identifying valid, novel, potentially, useful, and ultimately understandable patterns in data. IRPA 04-02-02-0004 EA004

  7. Perkembangan terkini • Perlombongan bertempoh • Perlombongan data dan visualisasi 3D • Alkhawarizmi Gugusan (Cluster Algorithm) • Teknik Dikretasi • WEKA –garam galian IRPA 04-02-02-0004 EA004

  8. Paradigma dan Metod dalam Penerokaan Pengetahuan Bertempoh • Jenis data bertempoh • Statik • Jujukan (sequence) • Timestamped • Bertempoh sepenuhnya (fully temporal) IRPA 04-02-02-0004 EA004

  9. Taksonomi konsep perlombongan bertempoholeh Roddick et al 2002 Roddick, J.F., Spiliopoulou, M. A Survey of Temporal Knowledge Discovery Paradigms and Methods. IEEE Transactions on Knowledge Management And Data Engineering. Vol 14. No 4, July/August 2002. IRPA 04-02-02-0004 EA004

  10. Contoh petua-petua bertempoh • A drop in atmospheric pressure precedes rainfall in 60 % of cases. • The sequence Committee Board  Council occurs approximately every month. • Marital status is becoming less of a determinant of voting behaviour. • Beachside flooding only occurs during spring high tides. • There is a higher incidence of earthquakes during and soon after periods of higher atmospheric pressure. • Some patients tend to develop reactions after two months with this combination of drugs. • The introduction of Euro caused a different pattern of buying behaviour in offshore markets. IRPA 04-02-02-0004 EA004

  11. Perlombongan data dan visualisasi 3D • Khasnya untuk data saintifik seperti, • pengkelasan protein • Bank data protein • Kompoun gugusan (clustering compound) • Khas untuk kompoun kimia • Teknik: • Geometric Hashing IRPA 04-02-02-0004 EA004

  14. Proses Dikretasi IRPA 04-02-02-0004 EA004

  15. Teknik Diskretasi IRPA 04-02-02-0004 EA004

  16. WEKA • Mari kita lihat programnya • WEKA IRPA 04-02-02-0004 EA004

  17. Kesimpulan • Menghasilkan satu alatan perlombongan data yang boleh digunakan oleh pelbagai pihak • Mengumpulkan pelbagai teknik dalam satu alatan dan akan dikemaskini secara berperingkat. • Memberi khidmat kepada mereka yang memerlukan mungkin secara percuma. IRPA 04-02-02-0004 EA004

  18. Semoga kita berjaya ! InsyaAllah IRPA 04-02-02-0004 EA004
