Saran - Penerapan algoritma Naive Bayes untuk memprediksi nilai ujian nasional siswa SMA berdas

BAB VI PENUTUP

6.2 Saran

Dari sistem yang dibuat masih diperlukan beberapa saran antara lain :

1. Prediksi yang dihasilkan sebaiknya tidak dijadikan acuan utama oleh pihak

sekolah, namun hanya sebagai sarana pendukung dalam memotivasi belajar

siswa menjelang Ujian Nasional.

2. Program bisa menerima masukan tidak hanya file berekstensi .csv saja, tapi

juga diharapkan dapat menerima masukan dari berbagai jenis file.

3. Program bisa lebih fleksibel dengan menerima masukan dengan jumlah

atribut yang bervariasi.

4. Proses pengolahan data training, proses prediksi, dan proses perhitungan

akurasi sistem sebaiknya tidak terintegrasi dengan database agar proses

menjadi lebih cepat.
