...Show More Authors

المستخلص يهدف هذا البحث الى تجاوز مشكلة البعدية من خلال طرائق الانحدار اللامعلمي والتي تعمل على تقليل جذر متوسط الخطأ التربيعي (RMSE) , أذ تم  استعمال طريقة انحدار الاسقاطات المتلاحقة  (PPR)    ,والتي تعتبر احدى طرائق اختزال الابعاد التي تعمل على تجاوز مشكلة البعدية (curse of dimensionality) , وان طريقة (PPR) من التقنيات الاحصائية التي تهتم بأيجاد الاسقاطات الاكثر أهمية في البيانات المتعددة الابعاد , ومع ايجاد كل اسقاط تتقلص البيانات بواسطة المركبات الخطية على طول الاسقاط ويتم تكرار العملية لايجاد اسقاطات جيدة لحين الحصول على افضل الاسقاطات والفكرة الاساسية لانحدار الاسقاطات المتلاحقة (PPR) هو نمذجة الانحدار المتعدد كمجموع للدوال غير الخطية للتراكيب الخطية للمتغيرات . ومن اجل التخلص من مشكلة البعدية تم استعمال اسلوبين الاسلوب الاول طريقة انحدار الاسقاطات المتلاحقة (PPR ) المقترحة والاسلوب الثاني طريقة الشبكات العصبية ( NN ) المتمثلة ( بالانبعاث الخلفي للخطأ )  وهي من الطرائق المستخدمة في اختزال الابعاد , وقد تم اجراء دراسة محاكاة للمقارنة بين الطرائق المستخدمة  وتم التوصل من خلال تجارب المحاكاة الى استنتاجات بينت ان الطريقة (NN) في هذا البحث اعطت نتائج افضل مقارنة بطريقة ( PPR )  اعتمادا على معيار جذر متوسط مربعات الخطأ (RMSE).

Different frequency distributions models were fitted to the monthly data of raw water Turbidity at water treatment plants (WTPs) along Tigris River in Baghdad. Eight water treatment plants in Baghdad were selected, with raw water turbidity data for the period (2008-2014). The frequency distribution models used in this study are the Normal, Log-normal, Weibull, Exponential and two parameters Gamma type. The Kolmogorov-Smirnov test was used to evaluate the goodness of fit.  The data for years (2008-2011) were used for building the models. The best fitted distributions were Log-Normal (LN) for Al-Karkh, Al-Wathbah, Al-Qadisiya, Al-Dawrah and, Al-Rashid WTPs. Gamma distribution fitted well for East Tigris and Al-Karamah
