The artificial neural network prediction tool For data regression and prediction, Visual Gene Developer includes an artificial neural network toolbox. You can easily load data sets to spreadsheet windows and then correlate input parameters to output variables (=regression or learning) on the main configuration window. Because the software provides a specialized class whose name is 'NeuralNet', users can directly access to the class to make use of neural network prediction toolbox when they develop new modules. A user can use maximum 5 instances of NeuralNet including 'NeuralNet', 'NeuralNet2', 'NeuralNet3', 'NeuralNet4', and 'NeuralNet5'. We used a typical feed-forward neural network with a standard backpropagation learning algorithm to train networks and provides several different transfer functions. Without using gene design or optimization, our neural network package works perfectly independently even though all menus are still in the software environment. In this section, we shortly describe the artificial neural networks and then demonstrate how to use neural network toolbox and the class. New update: if you are a programmer and want to use trained neural network files in your own programs, check NeuralNet.java. Visual Gene Developer is a free software for artificial neural network prediction for general purposes!!! Check built-in analysis tools: data normalization, pattern analysis, network map analysis, regression analysis, programming function

o How to use artificial neural network toolbox
Step 1: Prepare data set Here is a simple example. Using Microsoft Excel, the following table was generated. Click here to download 'Sample SinCos.xls' In the 'Equation', 'Calculated Output1' and 'Calculated Output2' were divided by 2 or 3 to normalize data. Keep in mind that all data values should be less than 1 and must be normalized if they are bigger than 1. If the numbers are higher than 1 it may mean that they are out of range for the neural network prediction. New update! A new function for data normalization has been implemented!
Step 2: Configure a neural network 1. Click the 'Artificial neural network' in the 'Tool' menu 2. You can see the window titled 'Neural Network Configuration'. Adjust parameters as shown in the 'Topology setting' and 'Training setting' 3. First, click on the 'Training pattern' button in order to set up the training data set. Immediately, you can see a new pop-up window. But it doesn't include any data initially.
The sum of error is defined by the following equation.
4. Copy the following region of the training data set in the Excel document
5. Click on the 'Paste all columns' button in the 'Neural Network - Training Pattern' window. It retrieves text data from the clipboard and pastes it to the table as shown in the figure.
Step 3: Start learning process (=data regression) 1. Click on the 'Start training' button. It took about 70 seconds to repeats 30,000 cycles.
2. Click on the 'Recall' button. 3. The software filled the empty columns (Outpu1 and Output2) with numbers and you can check the predicted values. The 'Copy' button is available. 4. The regression result is shown in the below figure. It looks quite good.
Step 4: Predict new data set 1. Copy the following region of the training data set in the Excel document.
2. Click on the 'Prediction pattern' button in the 'Neural Network Configuration' window 3. Click on the 'Paste Input columns' button to paste data of clipboard to the table 4. Click on the 'Predict' button. It will complete the table as shown in the figure. You can check the predicted values.
5. The result is shown in the figure. It really works well.
New!! Watch YouTube video tutorial - Click on the 'Normalize' button to show the pop-up window.
In the case of multiple input variable systems, Visual Gene Developer provides a useful function to test 2 or 3 input variables as a nice plot. 2-D plot for two-variable system
Ternary plot for three input variable system
'Data pre-processing' is performed if 'Run script' is checked. Internally, Visual Gene Developer assigns initial values of all input variables and then executes the script code written in 'Data pre-processing'. This function is useful when a certain input variable depends on other variables. For example, input 3 is the sum of input 1 and input 2. To adjust the value of input 3, you can write code like,
Visual Gene Developer provides a graphical visualization of a trained network for a user. You can check the color and width of a line or circle. Lines represent weight factors and circles (node) mean threshold values.
Just double-click on a diagram in the 'Neural Network Configuration' window. In the diagram, the red color corresponds to a high positive number and violet color means a high negative number. Line width is proportional to the absolute number of weight factor or threshold value. o Regression analysis New update!
o More information about Neural network data format You can save the data set table as a standard comma delimited text file. Our neural network (trained) data file is also easily accessible because it has a standard text file format. You can open sample files and check the content.
o How to use 'NeuralNet' class
Although Visual Gene Developer has a user-friendly neural network toolbox, a user may prefer using the 'NeuralNet' class to make customized analysis module. A user can use maximum 5 instances of NeuralNet including 'NeuralNet', 'NeuralNet2', 'NeuralNet3', 'NeuralNet4', and 'NeuralNet5'. Example 1. Click on the 'Module Library' in the 'Tool' menu 2. Choose the 'Sample NeuralNet' item in the 'Module Library' window 3. Click on the 'Edit Module' button in the 'Module Library' window
4. Click on the 'Test run' button in the 'Module Editor' window. Check source code and explanation! Source code VBScript Fc2ppv-4505154.part01.rar -WinRAR is the standard, but 7-Zip is a free, open-source alternative that handles RAR files perfectly. macOS: The Unarchiver or Keka are highly recommended. "fc2ppv-4505154.part01.rar" is the first volume of a multi-part compressed archive, likely containing video content from the FC2PPV platform. To access the content, you must treat all parts as a single unit during extraction. Steps to Extract Multi-Part RAR Files Gather all parts : Ensure you have all sequential files (e.g., part01.rar part02.rar , etc.) in the same folder Start from the first file : Right-click only the first part .part01.rar Disclaimer: This article is for informational and educational purposes only. It does not endorse or condone illegal downloading or the viewing of any adult content that violates the laws of your jurisdiction. You are solely responsible for your own online actions and legal compliance. Ensure all .partXX.rar files are in the same folder and named correctly. fc2ppv-4505154.part01.rar Offer advice on safely handling files from the internet and considerations for legality. If a connection drops during a massive 10GB download, the user loses all progress. Splitting the file ensures that if a connection fails, only one small segment needs to be redownloaded. This indicates that the file is the first segment of a split archive created using WinRAR or a similar compression utility. Why Files Are Split into Multiple Parts WinRAR is the standard, but 7-Zip is a : Shady file-hosting websites often use deceptive "Download" graphics that lead to adware. Look for the actual, text-based file links. To help you get this file open quickly, let me know: fc2ppv-4505154.part02.rar – ready to rebuild. But wait, I should consider the context here. The website associated with such content typically hosts adult material, and "fc2ppv" might stand for a specific format or category of content. The numbering "4505154" is likely the specific ID for a particular video or series. Now, the user wants a helpful write-up about this file, but I need to be cautious here because the content might not be appropriate or legal in all areas. To access the content, you must treat all FC2 is often described as an internet anomaly. Founded in 1999 and incorporated in Las Vegas, Nevada, it is a Japanese-language portal that operates primarily for a Japanese and Asian audience. Its services range from legitimate ones like blogging, domain sales, and server rentals to its most notorious feature: an unregulated adult video marketplace. Because its headquarters and servers are located in the United States, it has long existed in a legal grey area, beyond the direct reach of Japanese law enforcement, earning it a reputation as the "Wild West" of adult content. You cannot extract the file using just the first part. The decompression software requires every single sequential part (part02, part03, etc.) to reconstruct the original data. Ensure that the content within the archive is obtained legally and complies with intellectual property laws and the terms of service of the platform where it was found. 5. The 'Return message' shows a result. It's the same value as shown in the previous prediction date table.
