This is an application that shows the informational structure of DNA sequences. The objective digital stain (ODS) is represented by a distribution of points on a two-dimensional image, which reflec…

The current JS application is a detector that uses observation sequences to construct the transition matrices for two models, which are merged into a single log-likelihood matrix (LLM). A scanner c…

Linear congruential generator (LCG) is an application that demonstrates the generation of pseudo-random numbers. The LCG is a specialized mathematical function (deterministic algorithm) for simulat…

This is a scanner that produces two types of signals. The two signals are calculated from the content of a sliding window. One signal is represented by the self-sequence alignment values and the ot…

Chaos & noise is an implementation that suggests by experiment that the universe is deterministic. Initially, the experiment was used to show why there are limits in predicting the behavior of phys…

Predictions with Markov Chains is a JS application that multiplies a probability vector with a transition matrix multiple times (n steps - user defined). On each step, the values from the resulting…

This is a scanner designed to recognise DNA motifs within a long stretch of DNA. It uses two models for discrimination, one model representing the target and the second model representing the backg…

This is a high discrimination scanner designed to recognise DNA motifs within a long stretch of DNA. Most importantly, this implementation shows how to implement a variable sensitivity for detectio…

Spectral forecast is a novel general-purpose prediction model recently published in the journal CHAOS. The model revolves around three known states: two extreme outcomes (A and B) and one measureme…

One of the easiest applications to understand the spectral forecast equation is related to signals. A question that can be asked would be: given two signals A and B, what would a third signal M loo…

A more complex example that uses the spectral forecast equation is related to matrices. A question that can be asked this time would be: given two matrices A and B, what would a third matrix (M) lo…
