Here's another useful way to state the Bayes' rule for conditional probability (it just expands on what the OP wrote):
Note that here (1) is just the definition, (2) is a simple application of Bayes rule that we already know, and (3), (4) are various ways to rewrite (1) using factorization rules of the type P(ABC) = P(A|BC)P(B|C)P(C). Mentally, I find the following procedure useful:
This makes sense intuitively, if you think of conditioning as procedure of renormalizing the sample space in various ways. It's reasonable that you should be able to use Bayes' rule in the same way whether or not the probability space has been renormalized by conditioning.

Aikake Information Criterion
Maximum Likelihood
$AIC = -2*logL(\theta|y) + 2k$
$k = $ total number of parameters
Least Squares
$AIC = n*log(\frac{RSS}{n}) + 2k$
$RSS = SSE = \sum(y - h(x))^2$
$ n = $ number of samples

Matrix Form Pointwise Distances
$d_ij = ||x_i - y_j||^2 = ||x_i||^2 + ||y_j||^2 - 2<X_i,y_j>$
means that
$D = X + Y - 2X'Y$
Take the norm of X and Y i.e. X*X' or dot(X,X')
Normalize and calculate covariance
A * A.T (Hermitian!) / sqrt(diag(A.T * A) * diag(A.T * A).T)
