f-k filtering 频率波数滤波
F-K velocity filtering F-K 速度滤波
k-edge filtering k边滤波
K velocity filtering 速度滤波
Afterwards, we make K-L filtering to the data, then the signal-noise ratio of seismic data is improved greatly.
之后又对记录进行了K - L滤波，从而大大地提高了地震记录的信噪比。
Most of the content-based filtering algorithms are based on vector space model, of which Naive Bayes algorithm and K-Nearest Neighbor (KNN) algorithm are widely used.
基于内容的过滤算法大多数是基于向量空间模型的算法，其中广泛使用的是朴素贝叶斯算法和K最近邻（KNN）算法。
