Recent advancements in advanced neural networks have given rise to new adaptive learning strategies. Conventional learning strategies suffer from many issues, such as slow convergence and lack of robustness. To fully exploit its potential, these issues must be resolved. Both issues are related to the step-size, and momentum term, which is generally fixed and remains uniform for all weights associated with each network layer. In this study, the recently published Back-Propagation Algorithm with Variable Adaptive Momentum (BPVAM) algorithm has been proposed to overcome these issues and improve effectiveness for classification. The study was conducted on various hyperparameters based on the grid search approach, then the optimal values of hyperparameters have trained these algorithms. Six cases were considered with varying values of the hyperparameter to evaluate the impact of the hyperparameter on the training models. It is empirically proven that the convergence behavior of the model is improved in terms of the mean and standard deviation for accuracy and the sum of squared error (SSE). A comprehensive set of experiments indicated that the BPVAM is a robust and highly efficient algorithm.

Gelişmiş sinir ağlarındaki son gelişmeler, yeni uyarlanabilir öğrenme stratejilerine yol açmıştır. Geleneksel öğrenme stratejileri, yavaş yakınsama ve sağlamlık eksikliği gibi birçok sorundan muzdariptir. Potansiyelinden tam olarak yararlanmak için bu sorunların çözülmesi gerekir. Her iki konu da adım boyutu ve genellikle sabit olan ve her ağ katmanıyla ilişkili tüm ağırlıklar için tek tip kalan momentum terimi ile ilgilidir. Bu çalışmada, bu sorunların üstesinden gelmek ve sınıflandırma etkinliğini artırmak için yakın zamanda yayınlanan Değişken Uyarlanabilir Momentumlu Geri Yayılım Algoritması (BPVAM) algoritması önerilmiştir. Çalışma grid arama yaklaşımına dayalı olarak çeşitli hiperparametreler üzerinde yürütülmüş, daha sonra hiperparametrelerin optimal değerleri bu algoritmaları eğitmiştir. Hiperparametrenin eğitim modelleri üzerindeki etkisini değerlendirmek için hiperparametrenin değişen değerlerine sahip altı durum ele alındı. Modelin yakınsama davranışının, doğruluk için ortalama ve standart sapma ve karesel hatanın toplamı (SSE) açısından iyileştirildiği deneysel olarak kanıtlanmıştır. Kapsamlı bir deney seti, BPVAM'nin sağlam ve yüksek verimli bir algoritma olduğunu gösterdi.
