AB  - Bu çalışmada, düşükyoğunluklu polietilenin (DYPE) kompleks dielektrik fonksiyonunun gerçek ve sanalbileşenlerinin (e’ ve e’’) hem polianilin (PANI) katkısına hem de sıcaklığa bağlı değişimlerinin, genelleştirilmişregrasyon sinir ağları (GRSA) metoduyla yüksek doğrulukla tahmin edilebileceği gösterilmiştir.Bunun için öncelikle, saf DYPE ve kütlece % 0,7, %1 ve %3 PANI katkılandırılmışDYPE/PANI kompozitler fimler hazırlanmış ve ilgili numunelerin 20 °C, 50 °C ve80 °C’de e’ ve e’’ bileşenlerinin frekansabağlı değişimleri dielektrik spektroskopisi yöntemiyle deneysel olarakbelirlenmiştir. Ardından, dielektrik parametrelerin tahmin değerlerine karşılıkgerçek değerlerine göre çizilen grafikler yardımıyla, GRSA modelinin ilgiliparametrelerin tayinindeki başarı performansı Re’ =0,9998 ve Re’’ =0,9365olarak tespit edilmiştir. Bu noktadan hareketle, GRSA modeli önce mevcutnumunelerin 35 °C, 65 °C ve 95 °C sıcaklıklarda frekansa bağlı olarak e’ve e’’ bileşenlerinindeğişimini tahmin etmekte kullanılmıştır. Ardından, deneysel olarak hiçüretilmemiş iki faklı kompozit için (%1,5 ve %6 PANI katkılı DYPE) 20 °C, 35 °C,50 °C, 65 °C, 80 °C ve 95 °C’de e’ ve e’’bileşenlerininfrekansa bağlı değişimleri GRSA metodu ile önerilmiştir. Böylelikle, hiçdeneysel olarak üretilmemiş bu numunelerin dielektrik parametreleri sıcaklığave frekansa bağlı olarak belirlenebilmiştir.
