Knowledge Embedded Automatic Model Generation in Microwave Design Using Knowledge Based Artificial Neural Networks

Yapay sinir ağları RF / mikrodalga modelleme ve tasarımı için güçlü bir teknik olarak ortaya çıkmıştır. Yapay sinir ağlarının nöron sayısı ve örnekleme verileri gibi gerekli eğitim parametrelerini kullanıcının ekstra çabası olmadan kullanabilen otomatik model üretimi, arzu edilen doğrulukta etkili bir model sağlayabilir. Bu çalışmada, ön bilgi ile otomatik model üretim tekniğini birleştiren verimli bir modelleme stratejisi önerilmiştir. Bu kombinasyonun amacı, zaman alan iyi model cevabına olan ihtiyacı azaltmak ve kaba modeli kullanan otomatik model üretim algoritmasının performansını modelleme esnasında arttırmaktır. Otomatik model üretimi, ön bilgi giriş yöntemi sayesinde önceki yöntemlere kıyasla daha az nöron ve eğitim verisi gerektirmektedir. Sarmal endüktans modeli, bu tekniğin doğruluk ve zaman tüketimi açısından hem avantajlarını hem de geçerliliğini kanıtlamak için hesaba katılmıştır.

Mikrodalga Tasarımında Bilgi Tabanlı Yapay Sinir Ağlarını Kullanarak Bilginin Gömüldüğü Otomatik Model Üretimi

Artificial neural networks have emerged as a powerful technique for RF/microwave modeling and design. Artificial neural network parameters as number of neurons, sampling data, which are necessary for training can be utilized through automatic model generation without extra effort of user and can provide an efficient model with desired accuracy. In this work, an efficient modeling strategy combining a prior knowledge with automatic model generation technique is proposed. The aim of this combination is to decrease the need for time consuming fine model response and to increase the performance of automatic model generation algorithm using coarse model during the modeling process. Automatic model generation requires less neuron and training data compared to former methods via prior knowledge input method. Spiral inductor model is considered to demonstrate both the advantages and the validity of this technique in terms of accuracy and time consumption.
