Imports System





Public Class Form1
    '贝叶斯分类
    '使用Accord.IO里的的excel读取类
    Dim table As DataTable = New ExcelReader("E:\pro\books\AI_.net\src\AI_learn\learnai-1\data\examples.xls").GetWorksheet("Classification - Yin Yang")
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        '读取样本
        ' 转换datatable为输入输出数组
        Dim inputs As Double()() = table.ToJagged(Of Double)("X", "Y")
        Dim outputs As Integer() = table.Columns("G").ToArray(Of Integer)()
        '绘制数据
        ScatterplotBox.Show("样本数据", i
