Simbrain

Simbrain is a free, portable neural network software for Windows. This software helps you create and analyze artificial neural networks. It comes with a wide number of sample neural networks which can directly be imported and studied. To start from the scratch, you can build a network by adding new neurons, setting source neurons, connecting them with all to all or one to one connection, inserting network (Backprop, Competitive Network, Echo State Network, Feed Forward Network, LMS, SRN, etc.), adding neuron groups (SOM, WTA, etc.), etc. It lets you configure network preferences including network time step, synapse visibility threshold, connections setting, etc.

There are various kinds of simulation to simulate created neural networks. These include simulations of Actor-Critic, Agent Trails, and Cortical Circuit problems. You can visualize network simulation with bar charts, pie charts, histograms, time series, projection plot, and raster plot. It also lets you run scripts to perform custom simulations. It provides Coupling Manager and Coupling List tools too. While simulation goes on, the time and iteration statistics are displayed on the main interface. A document viewer (New Doc Viewer) is also provided to add instructions to be included in a simulation.

Neural Networks

Neural Networks is a free neural network software. It can be used for simulating neural networks and other forms of data. This tool visually demonstrates the feedforward backpropagation algorithm. There is visual feedback for weight adjustments and error analysis. You can import your neural network datasets to this software and create new neural nets as well. Then you can run the back-propagation learning algorithm on the dataset. This software then predicts outcomes for the set of input values.

Neural Network supports graphical modification and creation of neural networks. This allows for separate training and test sets, where the network is trained by the training set. Also, it features a Construction Wizard. This feature lets the applet load plain comma-delimited text files as data, and construct an appropriate neural network for it.

The good part of this software is that its interface is very clean and intuitive. Separate sections to select a tool to construct and edit the neural network. Then you can switch between Create and Solve mode to design and test your neural networks.

JustNN

JustNN is another free neural network software for Windows. Using this free software, you can train, validate, and query neural networks.

You can start with some exercises to get familiar with the software, such as simulation of XOR, Color Circle, Horse Races, etc.

To start with neural networks, you can create a grid with input columns, output columns, training example row, validating example row, and querying example row. You can add grid cell values as integer, real, boolean, and text. You can check the created grid to find problems in it and fix them accordingly. From the formed grid, a neural network can be created with input nodes, hidden nodes, output nodes, and connection weights. You can then start the learning process using Action > Start Learning option. And for this, you can set up some control options like learning rate, validating rules, slow learning options, target error stops, etc. The display mode can be set to Grid, Network, Input Importance, or Learning Progress Graph. You can view the related information of a created network including learning cycles, training error, etc.

Sharky Neural Network

Sharky Neural Network is another free neural network software to study neural network classifications.

• It lets you generate learning points by selecting amount and arrangement (square cartesian, circle cartesian, square radial, circle radial). You can save generated points as a points or text file.
• You can select a shape to display learning points on the graph like XOR, circle, square, diamond, ring, face, etc. Also, you can select what to show on the points graph including points, points and network answer, points and areas, or network answers.
• From Learn tab, you can configure some settings like order to sort learning points (fixed, random, swapping permutation, etc.), enable/disable premphase error and verify options, etc.
• To choose 2D graph display options, move to Draw tab. From here, you can select animation speed and error plots (Mean Squared Error, Verify Error, Error, ni) to draw.
• You can learn neural networks in different modes including Hard, Normal, and Soft, and you can select number of epochs for the same.
