Cross Validation Of Data

This function treats a matrix as a column-wise set of signals and circularly shifts each column so that it aligns with the first column of data so that the inner product between those columns is maximized with respect to all other shifts. USAGE:[dataout,lagout]=xcorAlign(data);If only 1 output is...

When developing a software package, it is useful to test changes by periodically running all the functions in a validation library. This function automates the process.VALIDATE DIRNAME runs each M-file in the directory DIRNAME. Each M-fileshould be a function that takes no inputs and returns a...

Using this script, you can generate a set of data regarding Sun Azimuth Positions at various instants of time for any location on Earth. This data can be used in many applications, like, in determination of orientation of any plane's azimuth from True North.The syntax is 'sun_azimuth_data' (no...

Association rules are a simple but very useful form of data mining that describe the probabilistic co-occurrence of certain events within a database. They were originally designed to analyse market-basket data, in which the likelihood of items being purchased together within the same transaction...

normxcorr2_general computes the normalized cross-correlation of matrices TEMPLATE and A. The resulting matrix C contains correlation coefficients and its values may range from -1.0 to 1.0.Limitations of normxcorr2:The documentation of normxcorr2 states that, "The matrix A must be larger than the...

In binary classification, the average accuracy obtained on individual cross-validation folds is a problematic measure of generalization performance. First, it makes statistical inference difficult. Second, it leads to an optimistic estimate when a biased classifier is tested on an imbalanced...

The idea is to give more emphasis in some examples of data as compared toothers by giving more weight. For example, we could give lower weights tothe outliers. The motivation to write this function is to compute percentilesfor Monte Carlo simulations where some simulations are very bad (in terms...

This function will summarize a 1-D vector of data (i.e. 1 column) based on what the user specifies as the statistic (e.g. mean, sum, etc.). It uses no loops, so it is extremely fast. However, it will use up memory as a result. I've included memory checks such that if you do not have enough...
