Probabilistic Principal Components Analysis. [VAR, U, LAMBDA] = PPCA(X, PPCA_DIM) computes the principal
％ component subspace U of dimension PPCA_DIM using a centred covariance
matrix X. The variable VAR contains the off-subspace variance (which
is assumed to be spherical), while the vector LAMBDA contains the
variances of each of the principal components. This is computed
using the eigenvalue and eigenvector decomposition of X.

The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the given time series and a time series that is consistent with the approximate model. The misfit is equal to zero if and only if the model is exact and the smaller the misfit is (by definition) the more accurate the model is. The considered model class consists of all linear time-invariant systems of bounded complexity and the complexity is specified by the number of inputs and the smallest number of lags in a difference equation representation. We present a Matlab function for approximate identification based on misfit minimization. Although the problem formulation is representation independent, we use input/state/output representations of the system in order

The ADC0803 family is a series of three CMOS 8-bit successive
approximation A/D converters using a resistive ladder and
capacitive array together with an auto-zero comparator. These
converters are designed to operate with microprocessor-controlled
buses using a minimum of external circuitry. The 3-State output data
lines can be connected directly to the data bus.

The AVRcam source files were built using the WinAVR distribution
(version 3.3.1 of GCC). I haven t tested other versions of GCC,
but they should compile without too much difficulty.
* The source files for the AVRcam had the author name and copyright
information added back into them after the judging of the project,
since it states in the competition rules that the author s name
can not be present during their inspection.
* The included source files are the ones that were submitted for
the entry into the Circuit Cellar contest. I have continued to
develop the AVRcam, and have added several new features (such as
ignoring objects that aren t larger than a minimum size, removing
tracked objects that overlap with each, and some general
optimizations). If you are interested in the latest source,
email me at john@jrobot.net
* For more info about the AVRcam, check out http://www.jrobot.net
