本論文根據文獻[12]以及文獻[17],以此兩則文獻中提到的FCM-SC分群演算法的硬體架構和KFCM演算法的硬體架構為基礎,實作以非線性高斯核函式為核距離計算之KFCM[12] 再加上空間資訊[17] 後的分群演算法硬體電路,具有管線化以及可以同時計算所有分群之權重係數的能力。此架構改良了以往KFCM分群演算法對於有雜訊的資料做分群的問題,並且配合KFCM本身可以對非線性資料分群效果較好的能力,所以能夠廣泛地使用在許多的分群資料上,並且都有良好的辨識率。本論文使用FPGA實現我們提出的硬體架構,並使用人工雜訊圖片作為實驗測試資料。實驗結果顯示本架構對於有雜訊的非線性資料分群效果確實較KFCM佳,且架構簡單提供了日後高度的延伸性。
