In the case of $\\\ell=2$ all such norm-Euclidean fields havebeen identified, but for $\\\elleq 2$, little else is known. We give the firstupper bounds on the discriminants of such fields when $\\\ell>2$. Our methodslead to a simple algorithm which allows one to generate a lis...
Euclidean范数指得就是通常意义上的距离范数。比如||X||=ρ(X,0)=Sqrt(X1^2+X2^2+...+Xn^2)
We give examples of Generalized Euclidean but not norm-Euclidean number fields of degree greater than 2. In the same way we give examples of 2-stage Euclidean but not norm-Euclidean number fields of degree greater than 2. In both cases, no such examples were known. 关键词: Turing's method...
d1_d2_jac_psim = psim2(dtm1_2, dtm2_2, method = "jaccard", norm = "none") str(d1_d2_jac_psim) 生成了一个200个数值的相似性系数。 2、cosine距离 d1_d2_cos_sim = sim2(dtm1, dtm2, method = "cosine", norm = "l2") 3、Euclidean 距离 x = dtm_tfidf_lsa[1:300, ] y...
