Consume
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}"); } } }
