Configuration Files

MainConfig.m

Elements description

• terrain_number: The string with the terrain number ("13" for this group).
• training_percentage: The percentage of the original set to use in training set.
• simulation_plot: The boolean flag to enable/disable the simulation plot.
• test_set_error_plot: The boolean flag to enable/disable the plot of error in test set.
• simulation_error_plot: The boolean flag to enable/disable the plot of error in simulation.
• sets_from_file: The boolean flag to enable/disable the use o training/test sets from specific files.
• training_set_path: The path to training set if set_from_file flag is true.
• training_set_path: The path to test set if set_from_file flag is true.

NeuralNet.m

Elements description

• layers: The layers architecture (ei: [2, 30, 10, 1] including the input and output layers).
• eta: The learning rate.
• epsilon: The error dimmension.
• weight_init: The weight initialization mode (RANDOM or FAN_IN).
• activation: The activation function (TANH or EXPONENTIAL).
• momentum: The momentum coeficient (must be between 0 and 1).
• weight_decay: The weight decay proportion.
• max_epochs: The max epochs for the training.
• learning: The learning mode (BATCH or INCREMENTAL).
• optimization: The optimization of backpropagation (SGD or ADAPTIVE_ETA or ADAM).
• alfa: The adaptive eta alfa parameter.
• beta: The adaptive eta beta parameter.
• error_horizon: The adaptive eta k parameter.
• output_funtion: The output function (LINEAR).
• beta_1: The beta 1 Adam parameter.
• beta_2: The beta 2 Adam parameter.
• adam_epsilon: The epsilon Adam parameter.

Building Project

This project uses octave with statistics octave package previuos installed.

To install statistics pacakage in octave execute the following command in the Octave's Command Window:

	pkg install -forge statistics

Run the project by executing the following command in the Octave's Command Window having as working directory the project folder:

	source main.m
