The mathematical principle behind cosine similarity is rooted in linear algebra and trigonometry. Given two vectorsAandB, the cosine similarity (cosθ) can be calculated using the dot product and vector magnitudes as follows: $$ \cos \theta = \frac{{A \cdot B}}{{\|A\| \cdot \|B\|}}...
for i in range(len(x)): xi = x[i] - mean(x) yi = y[i] - mean(y) calc.append(xi * yi) return sum(calc)/(len(x) - 1) a = [1,2,3,4,5] ; b = [5,4,3,2,1] print(covariance(a,b)) 协方差的计算方法是从每一对变量中减去各自的均值。然后,将这两个值相乘。 如果...
