In the circuit below, assume ideal op-amp, find Vout? To obtain the weights, you may simply pass identity matrix to the transform method: Each column of the coef matrix above shows the weights in the linear combination which obtains corresponding principal component: For example, above shows that the second principal component (PC-2) is mostly aligned with sepal width, which has the highest weight of 0.926 in absolute value; Since the data were normalized, you can confirm that the principal components have variance 1.0 which is equivalent to each coefficient vector having norm 1.0: One may also confirm that the principal components can be calculated as the dot product of the above coefficients and the original variables: Note that we need to use numpy.allclose instead of regular equality operator, because of floating point precision error. So, PC-2 grows as sepal width decreases and PC-2 is independent of changes in petal length. Use TfidfVectorizer instead.
