Abstract

In this study, an Artificial Neural Network (ANN) model was suggested and trained to predict the quantum defect values of alkali atoms. The dataset was divided into training and testing subsets with a % 60 – % 40, respectively. To prevent overfitting, the number of training epochs was limited to 250, and the learning rate was set to 0.25. The training process employed the Gradient Descent optimization algorithm for updating the network weights. Two different activation functions, ReLU and Swish, were utilized to evaluate their impact on prediction accuracy. The predicted quantum defect values obtained from the ANN were compared with corresponding experimental results to assess the model’s performance.

Alkali Atomlarda Kuantum Kusur Tahmini İçin Yapay Sinir Ağı Yaklaşımı

Abstract

Bu çalışmada, alkali atomların kuantum defekt değerlerini tahmin etmek amacıyla bir Yapay Sinir Ağı (YSA) modeli önerilmiş ve eğitilmiştir. Veri seti, sırasıyla %60 eğitim ve %40 test alt kümelerine ayrılmıştır. Aşırı öğrenmeyi önlemek amacıyla eğitim epoch sayısı 250 ile sınırlandırılmış ve öğrenme oranı 0.25 olarak belirlenmiştir. Ağ ağırlıklarının güncellenmesinde Gradient Descent optimizasyon algoritması kullanılmıştır. Tahmin doğruluğu üzerindeki etkilerini değerlendirmek amacıyla ReLU ve Swish olmak üzere iki farklı aktivasyon fonksiyonu kullanılmıştır. YSA ile elde edilen kuantum defekt tahminleri, karşılık gelen deneysel sonuçlarla karşılaştırılarak modelin performansı değerlendirilmiştir.
