Nonlinear Regression with GeneXproTools 4.3: Predicting Evaporation

This video shows how to create nonlinear regression models with GeneXproTools 4.3, focusing on: (1) Data analysis and visualization; (2) Creating the baseline multilinear regression model in Excel; (3) Preparing the data for training and testing; (4) Loading the data and creating a model in GeneXproTools; (5) Generating the model code (matlab code, expression tree, and mathematical expression); (6) Deploying and scoring a model in Excel; and (7) Evaluation of the importance of model variables.

Time Series Prediction in Testing Mode

By creating a model in Testing Mode, you have more control over the quality of the model at making predictions. Now in GeneXproTools 4.3, by using the Import Models feature, it’s possible to create a model while in Testing Mode and then import it from a different run primed for prediction. This video shows how to do this in GeneXproTools using the monthly closings of the Dow-Jones industrial index. It also shows the difference between Testing Mode and Prediction Mode in GeneXproTools using a very simple time series example.

Classification Video

This quick tour to Classification uses a well-known dataset for diagnosing breast cancer as either benign (0) or malignant (1). It covers all the basic steps of predictive modeling, including: (1) Loading training and testing data, (2) Creating a model, (3) Evaluating the predictive accuracy of a model, (4) Generating code automatically, (5) Optimizing a model, (6) Simplifying a model, (7) Choosing the set of functions to work with, (8) Choosing different architectures or model plans, (9) Experimenting with different numerical constants, (10) Exploring different fitness functions, and (11) Making predictions with the evolved models. All the video takes are real-time modeling sessions without cuts to give you a feel for how easy it is to model with GeneXproTools. The dataset used throughout the video consists of a total of 524 cases, of which 350 are used for training (that is, for building the models) and 174 for testing the predictive accuracy of the generated models.

Function Finding Video

This quick tour to Function Finding shows how to do nonlinear regression with GeneXproTools using real-world production data of 446 firms with three independent variables.

All the video takes are real-time modeling sessions without cuts to give you a feel for how easy it is to model with GeneXproTools. In this particular case, you’ll see that explaining Production as a function of Labor, Material, and Capital is an easy problem for GeneXproTools and exceptionally good models are obtained in virtually all runs.

Time Series Prediction Video

This quick tour to Time Series Prediction shows how easy it is to make predictions with GeneXproTools using Dow-Jones industrial historical data. It covers all the basic steps of predictive modeling, including: (1) Loading and transforming a time series, (2) Creating models in testing mode, (3) Evaluating the predictive power of a model, (4) Creating models in prediction mode, (5) Generating code automatically, (6) Optimizing a model, (7) Simplifying a model, (8) Experimenting with different embedding dimensions and delay times, (9) Choosing the set of mathematical functions to work with, (10) Choosing different architectures or model plans, (11) Experimenting with different numerical constants, and (12) Exploring different fitness functions. All the video takes are real-time modeling sessions without cuts to give you a feel for how easy it is to make predictions with GeneXproTools. For all the runs of this video, each value from the original raw time series (data file dj.dat obtained from the Time Series Data Library) was replaced by its moving average using a smoothing period of 10.


Logic Synthesis Video

This quick tour to Logic Synthesis uses the well-known odd-3-parity function which, of the logical functions with three inputs, is one of the hardest to model with learning algorithms. The video covers all the basic steps of logic circuit design with GeneXproTools, including: (1) Loading the rule table, (2) Creating logic circuits with only NOT-AND-OR, (3) Simplifying a logic circuit, (4) Generating code automatically in 16 programming languages, (5) Exploring different linkers, (6) Creating logic circuits with just NAND gates, (7) Creating logic circuits with just NOR gates, (8) Creating logic circuits with just MUX gates, (9) Creating logic circuits with only NOT-AND-XOR, (10) Creating logic circuits using all kinds of gates and convert them immediately into canonical logical systems, (11) Optimizing a logic circuit, and (12) Exploring different fitness functions. All the video takes are real-time modeling sessions without cuts to give you a feel for how easy it is to design logic circuits with GeneXproTools.

"Finally, a world class user interface in the field of genetic programming and evolutionary computation !! GeneXproTools is simply unrivaled in its marvelous user interface, the breadth of its Fitness Functions, the choice and flexibility in Math and Logic functions, the clarity of its final Model Presentation, and a built in panel for Scoring new data, right inside the interface. This kind of functionality and ease of use has never been seen before in the field of Genetic Programming. Additionally, Dr Ferreira's specific methodology of Gene Expression Programming makes important contributions to the field of evolutionary computation, and the various algorithms she has developed and deployed inside of GeneXproTools are brilliantly conceived, and her methodologies evolve highly predictive models that solve real business problems. GeneXproTools is an extraordinary structural tour de force."

"Gene Expression Programming, combined with GeneXproTools, allow us here at Mercator GeoSystems to explore new and exciting methods for spatially modelling the relationship between a company's outlets and their customers. The GeneXproTools software is simple to use, well-designed and very flexible. In particular the ability to load training data from a database, and the option to create models in the programming language of our choice, really make this product stand out. Product support is excellent and very responsive - heartily recommended!"

"As a professional software developer, I could have attempted to read up on all the latest developments in the field of evolutionary programming and start writing my own modeling tools. One look at the GeneXproTools demo, however, was enough to convince me of the absurdity of that thought. Not only does GeneXproTools have all the power that I would ever need, but it also allows me to customize all parts of the modeling process. I don't have to know the first thing about evolutionary algorithms and yet I can write my own grammars or fitness functions if I wanted to. It is obvious that a huge amount of work went into the making of GeneXproTools, and I am now a very happy customer. Keep up the great work, Gepsoft!"

"I've been working as a coastal engineer and mathematical modeler for more than 10 years and now I'm using GeneXproTools to discover complex nonlinear relations that exist in hydraulic and wave processes. For example, GeneXproTools recently helped me establish several explicit approximations to the Wave Dispersion Equation and now with the new version, which allows more independent variables, fitness functions and unlimited records, I plan to develop my own formulae to evaluate the wave overtopping of breakwaters and seawalls. Thanks Gepsoft for providing such an exciting, creative and useful software tool to the scientific community."

"GeneXproTools is being used to look at problems involving parasite populations, where the data is highly skewed. The results using GeneXproTools are considerably better than those obtained using conventional statistics."

"We are using GeneXproTools for modeling the rainfall-runoff process and time series forecasting. GeneXproTools has a nice graphical user interface system and a lot of flexibility in choosing the type of input file. Configuring the problem setup, running and visualizing the graphical outputs with GeneXproTools is indeed user friendly. Being able to get the final model in the languages of our choice makes GeneXproTools stand out from other packages."
