1 I cedimenti possono essere anche dovuti a costipamento, ovvero all’espulsione di aria da un terreno non saturo come conseguenza dell’applicazione di energia di costipamento (vedi capitolo 2), a deformazioni di taglio a volume costante, che si verificano nei terreni saturi e poco permeabili in condizioni non drenate

Dimensionality Reduction - Stanford University

1 2 But that vector is not a unit vector, since the sum of the squares of its compo-nents is 5, not 1. Thus to get the unit vector in the same direction, we divide each component by √ 5. That is, the principal eigenvector is 1/ √ 5 2/ √ 5 and its eigenvalue is 7. Note that this was the eigenpair we explored in Exam-ple 11.1.

function sc: IR →(0,1) defined by the expression sc(x) = 1 1+e−cx. The constant ccan be selected arbitrarily and its reciprocal 1/cis called the temperature parameter in stochastic neural networks. The shape of the sigmoid changes according to the value of c, as can be seen in Figure 7.1. The graph shows the shape of the sigmoid for c= 1 ...

between 0 and 1. In fact, since weights are real-valued, the output might even be negative; z ranges from ¥ to ¥. Figure 5.1 The sigmoid function s(z) = 1 1+e z takes a real value and maps it to the range [0;1]. It is nearly linear around 0 but outlier values get squashed toward 0 or 1.
