我對Haskell來說很新,並且一直試圖解決這個問題。Haskell - 將另一個參數的每個元素傳遞給函數
我有一個函數:
sumNodeError :: Node -> Layer -> Double
sumNodeError node childLayer = foldl (+) 0 (listProduct (weights node) (errors childLayer))
calculateNodeError :: Node -> Layer -> Double
calculateNodeError node childLayer = (sumNodeError node childLayer) * (value node) * (1.0 - (value node))
-- problem is in this function
calculateErrors :: Layer -> Layer -> Layer
calculateErrors layer childLayer = Layer (nodes layer)
(map calculateNodeError (nodes layer) childLayer) -- problem, need to map each of the nodes in the layer, and the childLayer to calculateNodeError
(teacherSignals layer)
(learningRate layer)
我需要通過每個(nodes layer)
和childLayer
運作calculateNodeError
的代碼的其餘部分(不太多),可以在這裏找到,如果你需要:https://github.com/kennycason/haskell_nn/
非常感謝。
非常感謝,這工作,我甚至不知道我可以編寫這樣的功能! :) –
