تقدير دالة الأنحدار اللامعلمي باستخدام بعض الطرائق اللامعلمية الرتيبة
...Show More Authors

المستخلـص

تم في هذا البحث دراسة الطرائق اللامعلمية الرتيبة لتقدير دالة الأنحدار اللامعلمي، ومعالجة القيم الشاذة الموجودة في دالة الأنحدار اللامعلمي لجعل الدالة رتيبة (متزايدة أو متناقصة).

لذا سنقوم أولاً بتقدير دالة الأنحدار اللامعلمي بإستخدام ممهد Kernel ومن ثم تطبيق الطرائق الرتيبة لجعل الدالة متزايدة إذ سنتناول ثلاث طرائق للتقدير:-

1- طريقة stern)-Mukerjee) إذ سيتم الأستفادة من الحدود الدنيا والحدود العليا للمجاميع الجزئية للبيانات لتعديل مقدر Kernel بإستخدام دالة تقلص (Shrunken).

2- إعتماداً على الطريقة الأولى سيتم أستخدام الحالة الخاصة لدالة التقلص (Shrunken) عندما بوصفها طريقة أخرى مستقلة عن الطريقة الأولى.

3- خوارزمية الأنحدار الرتيب ذو المربعات الصغرى (LSIR) لمعالجة القيم الشاذة.

 

وسيتم في هذا البحث مقارنة بين هذه الطرائق من خلال إيجاد متوسط مربعات الخطأ والكفاءة النسبية لكل مقدر ولكل أنموذج في الجانب التجريبي من خلال أسلوب محاكاة مونتي كارلو (Monte Carlo)، وتم ايضا مقارنة الطرائق من خلال التطبيق على بيانات لخمسة وعشرين مريضاً مصابين بضغط الدم (العالي والواطئ) وتم التوصل الى أن طريقة stern)-Mukerjee) هي الأفضل من بين الطرائق الأخرى.

Real-Time Cloth Simulation on Virtual Human Character Using Enhanced Position Based Dynamic Framework Technique
...Show More Authors

     Cloth simulation and animation has been the topic of research since the mid-80's in the field of computer graphics. Enforcing incompressible is very important in real time simulation. Although, there are great achievements in this regard, it still suffers from unnecessary time consumption in certain steps that is common in real time applications.   This research develops a real-time cloth simulator for a virtual human character (VHC) with wearable clothing. This research achieves success in cloth simulation on the VHC through enhancing the position-based dynamics (PBD) framework by computing a series of positional constraints which implement constant densities. Also, the self-collision and collision wit
