Kesimpulan
Saran
Departemen Statistika 2018 29
Metode terbaik untuk mengklasifikasikan Autism Screening Adult adalah
metode Adaptive Boosting dengan 10 variabel pertanyaan perilaku
dewasa saja baik secara biasa maupun dilakukan 10-cross validation
menghasilkan akurasi, presisi, dan recall sebesar 1 atau 100%
KESIMPULAN
Departemen Statistika 2018 30
Sebagai salah satu cara untuk mengklasifikasikan penyakit
autis pada penderita dewasa (>18 tahun) sebaiknya
mengeksplor variabel lebih banyak agar hasil penelitian lebih
valid dan sesuai dengan kondisi sebenarnya.
