Problem with Naive Bayes - Index was outside the bounds of the array #831
Description
examples.xlsx
Dear
I am a new guy in machine learning. I have a problem with Naive Bayers. I use code in tutorial about Naive Bayers.
This is my code:
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string FolderPath = openFileDialog1.FileName;
DataTable DanhSach = new ExcelReader(FolderPath).GetWorksheet("Classification - Yin Yang");
double[][] inputs = DanhSach.ToJagged("X", "Y");
// double[][] outputs = DanhSach.ToJagged("G", "K");
int[] outputs = DanhSach.Columns["G"].ToArray();
//ScatterplotBox.Show("Yin-Yang", inputs, outputs).Hold();
var teacher = new NaiveBayesLearning<NormalDistribution>();
var nb = teacher.Learn(inputs, outputs);
int numberOfClasses = nb.NumberOfClasses; // should be 2 (positive or negative)
int nunmberOfInputs = nb.NumberOfInputs; // should be 2 (x and y coordinates)
// Classify the samples using the model
int[] answers = nb.Decide(inputs);
// Plot the results
ScatterplotBox.Show("Expected results", inputs, outputs);
ScatterplotBox.Show("Naive Bayes results", inputs, answers)
.Hold();
}
I have attach file data which I download from tutorial.
Then I build this codes. And I have a bug is "Index was outside the bounds of the array". I don't know why. Please help me. Thanks very much.
