局部敏感哈希算法进行论文的相似性比对
您好,請問你知道該如何修改 lsh裡的 distance function嗎?
lshash.py 裡 第298行:
@staticmethod
def euclidean_dist(x, y):
""" This is a hot function, hence some optimizations are made. """
diff = np.array(x)-y
return np.sqrt(np.dot(diff, diff))
我想修改裡面的計算方法,我裡面的把diff改成diff = np.array(x)-(mean(x)-mean(y))-y
修改後,我再使用 lsh.query([1,2,3,4,5,6],distance_func="euclidean")
跑出來的結果和修改前完全一樣。
所以看起來 @staticmethod 無法直接這樣修改,請問您知道正確的修改方式嗎 謝謝您
请问您是如何在python3的环境上安装LSHash的?
