using System;
using MyMLAppML.Model;
namespace myMLApp
{
class Program
{
static void Main(string[] args)
{
// Add input data
var input = new ModelInput()
{
Col0 = "This restaurant was wonderful."
};
// Load model and predict output of sample data
ModelOutput result = ConsumeModel.Predict(input);
// If Prediction is 1, sentiment is "Positive"; otherwise, sentiment is "Negative"
string sentiment = result.Prediction == "1" ? "Positive" : "Negative";
Console.WriteLine($"Text: {input.Col0}
Sentiment: {sentiment}");
}
