In the other hand, it has been studied intensively a
group of mathematical models named Artificial Neural Networks, or simply,
neural networks. They are models that have the brain as source for basic
principles. In a short and not complete time line, the works have started in
1943 with McCulloch and Pitts proposing a general theory for learning machine;
1960, Rosenblatt and his collaborators studied the perceptron; 1961, Caianiello
created a learning algorithm based on hebb’s learning rule; 1970, use of Evolutionary
Algorithms by John Holland; and 1985, recognition
of the back-propagation by some group of scientists. In the current state of
the art, those methods based on learning machine are applied intensively for
modeling natural phenomena with high nonlinearity-level, nosy, but with some
hidden law that are difficult or even impossible for the current mathematical
theory captures.
Here is studied the application of neural networks for
modeling gene expression. In a more precise way, gene expression is modeled via
estimation, once the sharp value is not possible to be known, due to
technological limitation and biological fluctuation.
