BAB 5 KESIMPULAN DAN SARAN 5.1 Kesimpulan a. Jaringan RBF yang dilatih menggunakan algoritma pembelajaran Extreme Learning Machine (ELM-RBF) tidak hanya memiliki akurasi lebih tinggi melainkan juga unggul dalam hal kecepatan training bila dibandingkan dengan algoritma SCG-TLF dan BP-MLP, yaitu tingkat akurasi 92,05% dan waktu training selama 5,43 detik. Dengan kata lain, Algoritma ELM memiliki akurasi 6,95% dan 27,95% lebih tinggi dan waktu training 132,57 detik dan 10,66 detik lebih cepat masing-masing terhadap algoritma SCG-TLF dan BP-MLP. b. Akurasi klasifikasi pada ELM-RBF menggunakan fitur input hasil reduksi PCA mencapai 94,62% dan waktu training selama 4,18 detik. Hal ini menunjukkan adanya peningkatan performansi akurasi sebesar 2,79% dan reduksi waktu training selama 1,25 detik terhadap penggunaan fitur input asli c. Penggunaan jumlah hidden neuron berbanding lurus dengan waktu training namun tidak berlaku pada tingkat akurasinya, sehingga penentuan jumlah hidden neuron yang tepat turut menentukan performansi jaringan ELM-RBF. 5.2 Saran Untuk pengembangan lebih lanjut, metode klasifikasi berbasis jaringan syaraf tiruan pada umumnya dan jaringan ELM-RBF pada khususnya dapat ditingkatkan pada level klasifikasi dengan data citra sidik jari yang lebih besar pada beberapa Database sidik jari yang tersedia di internet secara komersial seperti Database NIST. 65
