keras 的 example 文件 class_activation_maps.py 解析
生活随笔
收集整理的這篇文章主要介紹了
keras 的 example 文件 class_activation_maps.py 解析
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
該文件功能是實現一個CNN可視化，我不知道這個叫法算不算專業，可以參考別人寫的文章

應該就是看下神經網絡是通過關注哪部分區域預測出的最終結果
?
其基礎網絡是resnet50，get_cam_model函數中對其進行了一點修改，可參考下圖，看到修改了哪些地方
就是僅添加了兩層神經網絡，其他沒有動
預測后通過postprocess函數提取出感興趣的那個分類的channel，我把該函數簡化了一下，應該更容易理解一點
def postprocess(preds, cams, top_k=1):idxes = np.argsort(preds[0])[-top_k:][0]return cams[0, :, :, idxes]文件最后的代碼，我作了如下修改：
# 5. plot image+cam to original size
# plt.imshow(original_img, alpha=0.5)
plt.imshow(cv2.resize(class_activation_map,original_size), cmap='jet')
plt.savefig("res.jpg")
plt.show()看下效果圖
原圖
預測后結果的顏色圖譜
也就是說，他是根據這部分區域預測出的結果，這是一只金毛犬，下面可以把分類名稱打印出來
from keras.applications.imagenet_utils import decode_predictions
print(decode_predictions(preds))[[('n02099601', 'golden_retriever', 0.82736635), ('n02111129', 'Leonberg', 0.08901908), ('n02111277', 'Newfoundland', 0.008406928), ('n02104029', 'kuvasz', 0.007829149), ('n02099712', 'Labrador_retriever', 0.004909024)]]如果最后面代碼沒有修改的話，顯示結果為：
就是和原圖進行了一個疊加，顯示出，哪部分區域，是CNN得出最終預測結果的主要依據
——————————————————
下面是自己折騰時刻，不屬于正文
如果我把圖片旋轉一下，發現resnet幾乎無法識別了
[[('n02099601', 'golden_retriever', 0.2694396), ('n02113023', 'Pembroke', 0.16751677), ('n01514859', 'hen', 0.10281576), ('n02105251', 'briard', 0.03323859), ('n02102318', 'cocker_spaniel', 0.03284181)]]?
當然，如果水平翻轉，還是能識別到的，而且關注點也可以正確的找到
[[('n02099601', 'golden_retriever', 0.82862425), ('n02111129', 'Leonberg', 0.07444748), ('n02104029', 'kuvasz', 0.01596525), ('n02111277', 'Newfoundland', 0.015939327), ('n02099267', 'flat-coated_retriever', 0.0076823044)]]附修改后的神經網絡
