Part 2 – Predikisi Portofolio Saham Menggunakan Artificial Neural Network

Oleh: Svadev Prashant Mahasagara

Poin Penting

  • Artificial Neural Network (ANN) merupakan metode analisis yang meniru cara kerja sistem syaraf manusia yang belajar dari data/pengalaman historis melalui trial dan error
  • Trial & Error dalam ANN:
    1. Neuron dalam hidden layer
    2. Activation function
    3. Learning rate
    4. ANN Architecture
  • Kelebihan ANN:
    1. Lebih akurat
    2. Mudah untuk dikonsep
    3. Tingkat peminatan penggunaan ANN dalam penelitian sangat tinggi
  • Kekurangan ANN:
    1. Complex
    2. Lot of turning
    3. Time consuming
  • ANN dapat menganalisis data continuous dan data categorical, namun hanya dalam berupa angka. Jadi, data categorical harus ditransformasi menjadi bentuk numerik

Thoughts on ICT EXPO & ANJA 2016:

  • Nicely organized, especially the stands’ layout
  • Registration process doesn’t require lot of time, therefore the queue line isn’t much
  • Vast variety of tenants. ICT Expo & ANJA 2016 manage to brought various company related to telecommunication industry, so they can brought various content as the tenants of the stands
  • The visitor card is a nice feature of the event, it served as an identification of guests and also become a souvenir for the visitor as well.
  • The only minus point i found during the expo is that the main stage contents becoming really unattractive due to it’s location and the display from the tenants.
