$$T(n) = \sum _{i=0} ^{n} T(\frac {n}{i}) + \Theta(n \lg n) = something$$

$$T(n) = 2^{2^{2^{2^{2^{2^{2}}}}}} T(n/2) = 0 $$

$$ T(n) = \sum _{i=1}^n \sum _{j=1}^n \frac {i}{j} n$$

$$e^{i*Pi}=-1$$

SVM classification

$$h(x) = \sgn(\sum_{i=1}^m \alpha_i y_i k(x_i, x) + b )$$

Dot product

$$f(x,y) = \sum_{i=1}^m x_i y_i$$
