Training a Small Language Model AI Using Text Files, C#, and SQL Database

Azure

In the ever-evolving landscape of artificial intelligence, training language models has become a pivotal aspect of developing applications capable of understanding and generating human language. This article delves into the process of training a small language model AI using text files, C#, and an SQL database, providing a comprehensive guide with example code, files, and queries.

Step 1. Preparing the Text Data

To initiate the training process, a substantial dataset of text is required. For this example, we utilize a text file named sentences.txt, containing realistic and diverse sentences that the AI will learn from.

Example of sentences.txt

  • The quick brown fox jumps over the lazy dog.
  • Artificial intelligence is transforming industries worldwide.
  • Machine learning algorithms improve with more data.
  • Understanding natural language is a complex task.
  • Data scientists analyze patterns in large datasets.
  • Neural networks are inspired by the human brain.
  • AI applications are becoming increasingly common.
  • Programming languages like Python and C# are popular in AI development.
  • The future of AI is both exciting and uncertain.
  • Developers must ensure AI systems are ethical and unbiased.

Step 2. Setting Up the SQL Database

The next step involves setting up an SQL database to store the processed text data. We’ll create a database and a table to hold the tokenized text data.

SQL Commands to Create Database and Table.

CREATE DATABASE LanguageModelDB;
USE LanguageModelDB;
CREATE TABLE TextTokens (
    Id INT PRIMARY KEY IDENTITY(1,1),
    Sentence NVARCHAR(MAX),
    Tokens NVARCHAR(MAX)
);

Step 3. Tokenizing Text Data Using C#

With the database ready, we proceed to write a C# program that reads the text file, tokenizes the sentences, and stores the tokens in the SQL database. Tokenization involves breaking down the text into individual words or tokens, which can then be processed by the language model.

Text Data Class

public class TextData
{
    public string Sentence { get; set; }
    public string[] Tokens { get; set; }
}

Main Program

using System;
using System.Data.SqlClient;
using System.IO;
using Microsoft.ML;
using Microsoft.ML.Data;
public class TextData
{
    public string Sentence { get; set; }
    public string[] Tokens { get; set; }
}
class Program
{
    static void Main()
    {
        var context = new MLContext();
        var lines = File.ReadAllLines("sentences.txt");
        var data = new TextData[lines.Length];
        for (int i = 0; i < lines.Length; i++)
        {
            data[i] = new TextData { Sentence = lines[i] };
        }
        var dataView = context.Data.LoadFromEnumerable(data);
        var textPipeline = context.Transforms.Text
            .TokenizeIntoWords("Tokens", "Sentence")
            .Append(context.Transforms.Text.ProduceWordBags("Features", "Tokens"));
        var tokenizedData = textPipeline.Fit(dataView).Transform(dataView);
        var preview = context.Data.CreateEnumerable<TextData>(tokenizedData, reuseRowObject: false);
        using (SqlConnection connection = new SqlConnection("your_connection_string"))
        {
            connection.Open();
            foreach (var row in preview)
            {
                string query = "INSERT INTO TextTokens (Sentence, Tokens) VALUES (@Sentence, @Tokens)";
                using (SqlCommand command = new SqlCommand(query, connection))
                {
                    command.Parameters.AddWithValue("@Sentence", row.Sentence);
                    command.Parameters.AddWithValue("@Tokens", string.Join(" ", row.Tokens));
                    command.ExecuteNonQuery();
                }
            }
        }
    }
}

Replace "your_connection_string" with your actual SQL Server connection string. This program reads the sentences from the text file, tokenizes them, and inserts the tokens into the SQL database.

Step 4. Querying the SQL Database

Once the data is stored in the SQL database, you can query it to retrieve the tokenized sentences for further processing or analysis.

Example SQL Query

SELECT * 
FROM TextTokens;

This query will return all the sentences and their corresponding tokens stored in the database, allowing you to verify the tokenization process and use the data for training your language model.

In-Depth Explanation

  1. Tokenization and Data Storage: The tokenization process is crucial for breaking down sentences into individual components that the AI model can process. The TokenizeIntoWords method in the ML.NET library is used for this purpose, converting sentences into arrays of tokens. These tokens are then transformed into feature vectors using ProduceWordBags, which are essential for training the language model.
  2. Database Interaction: Storing the tokenized data in an SQL database provides a structured way to manage and query the training data. The C# program demonstrates how to read the text file, tokenize the sentences, and store the results in the database, making it easy to manage large datasets and retrieve data efficiently for training purposes.

Conclusion

By following these steps, you can effectively train a small language model AI using text files, C#, and an SQL database. This method offers a flexible and scalable approach to preparing and managing your training data, suitable for developing chatbots, text analysis tools, or other language-based applications. With this setup, you have a solid foundation for your AI projects, enabling you to leverage the power of language models to enhance your applications.

This comprehensive guide ensures that you understand each step of the process, providing you with the knowledge and tools to train your own language model AI successfully.
