Konvolüsyonel Sinir Ağlarında Hiper-Parametre Optimizasyonu Yöntemlerinin İncelenmesi

Öz

Konvolüsyonel Sinir Ağları (KSA), katmanlarının en az bir tanesinde matris çarpımı yerine konvolüsyon işleminin kullanıldığı çok katmanlı yapay sinir ağlarının bir türüdür. Özellikle bilgisayarlı görü çalışmalarında çok başarılı sonuçlar elde edilse de KSA hala birçok zorluk içermektedir. Daha başarılı sonuçlar elde etmek için geliştirilen mimarilerin giderek daha derinleşmesi ve kullanılan görüntülerin giderek daha yüksek kalitede olmasıyla daha fazla hesaplama maliyetleri ortaya çıkmaktadır. Hem bu hesaplama maliyetlerinin düşürülmesi, hem de başarılı sonuçlar elde edilebilmesi, güçlü donanımların kullanılmasına ve kurulan ağın parametrelerinin, başka bir deyişle hiper-parametrelerin optimize edilmesine bağlıdır. Yaptığımız bu çalışmada, KSA hiper-parametrelerinin optimize edilmesi için yaygın olarak kullanılan yöntemleri, optimize edilen hiper-parametreleri, bu parametreler için tanımlanan değer aralıklarını, veri setlerini ve elde edilen sonuçları inceledik. Yapılan çalışmaların eksik yönlerine, kullanılan yöntemlerin birbirlerine karşı zayıf ve güçlü yönlerine değindik. Sonuç ve değerlendirme bölümünde hiper-parametrelerin seçiminde dikkat edilmesi gereken noktalara, günümüzde sıklıkla kullanılan yöntemlere ve ileride kullanılabilecek metodolojilere değindik.
