Feature Selection In Autism Dataset Using Apriori Algorithm

Öz

Autism Spectrum Disorder is a neurodevelopmental disorder characterized by linguistic, cognitive, social, and communication delays. Accurate diagnosis of autism is important for effective intervention, and there are various clinical and non-clinical methods for the diagnosis of the disease. Machine learning techniques have increased significantly in this field recently. This study focuses on selecting the most relevant features from the Autism Spectrum Disorder Screening Data for Children located in the UC Irvine Machine Learning Repository. This dataset contains 21 features, and the aim of the study is to determine which features are more important. Apriori algorithm, an association rule mining technique, was used in the analysis of the dataset. Rules with minimum 33% support and minimum 90% confidence interval were obtained with the algorithm. Feature selection was performed based on these rules. The success of the proposed feature selection method was evaluated by comparing it with traditional methods. The experimental results obtained proved the validity of the proposed approach and sampling was performed for autism diagnosis. The proposed method can also be used for other datasets.

Apriori Algoritması Yardımıyla Otizm Veri Setinde Özellik Seçimi

Öz

Otizm Spektrum Bozukluğu, dilsel, bilişsel, sosyal ve iletişimsel gecikmelerle karakterize edilebilen nörogelişimsel bir bozukluktur. Otizmin doğru tanısı, etkili müdahale için önemlidir ve hastalığın tanısı için çeşitli klinik ve klinik olmayan yöntemler bulunmaktadır. Makine öğrenimi teknikleri son zamanlarda bu alanda belirgin olarak artmıştır. Bu çalışmada, UC Irvine Makine Öğrenmesi Deposunda yer alan Çocuklar İçin Otizm Spektrum Bozukluğu Tarama Verilerinden en alakalı özellikleri seçmeye odaklanmaktadır. Bu veri seti 21 özellik içerir ve çalışmanın amacı hangi özelliklerin daha önemli olduğunu belirlemektir. Veri setinin analizinde bir ilişki kuralı madenciliği tekniği olan Apriori algoritması kullanılmıştır. Algoritma ile minimum %33 destek ve minimum %90 güven aralığına sahip kurallar elde edilmiştir. Bu kurallara dayanarak özellik seçimi yapılmıştır. Önerilen özellik seçimi yönteminin başarısı, geleneksel yöntemlerle karşılaştırılarak değerlendirilmiştir. Elde edilen deneysel sonuçlar önerilen yaklaşımın geçerliliği ispat etmiş olup otizm tanısı için örnekleme yapılmıştır. Önerilen yöntem diğer veri setleri için de kullanılabilir durumdadır.
