Beyond document-level analysis, cosine distance is vital in word embeddings like Word2Vec or GloVe, where words are represented as high-dimensional vectors. These embeddings capture semantic meaning such that words with similar meanings are embedded close together in the vector space. Cosine distance ...
在sklearn中,我们可以通过参数weights来控制是否适用距离作为惩罚因子。 weights = 'distance' 1. score = [] var_ = [] krange=range(1,20) for i in krange: clf = KNeighborsClassifier(n_neighbors=i, weights = 'distance') cvresult = CVS(clf,x_new,y,cv=5) score.append(cvresult.mean())...

Cosine similarity is a measure of similarity between two vectors. It is widely used in machine learning where documents, words or images are treated as vectors. The similarity value is calculated by measuring the distance between two vectors and normalizing it by the length of the vectors: ...

In this work, we present a novel black-box boundary attack method based on the discrete cosine transform. It can generate the adversarial example with a low L2 distance and fewer query time. The test data shows that the proposed method can decrease the query times when it reaches the same ...
