ML Project Lifecycle Planning

When to Use This Skill

Use this skill when:

• Ml Project Lifecycle tasks - Working on plan ml projects using crisp-dm, tdsp, and mlops methodologies with proper phase gates and deliverables
• Planning or design - Need guidance on Ml Project Lifecycle approaches
• Best practices - Want to follow established patterns and standards

Overview

ML project lifecycle methodologies provide structured approaches for planning, executing, and deploying machine learning systems with appropriate governance and quality gates.

{
    public async Task TrackExperiment(
        string experimentName,
        Func<Task<ExperimentResult>> experiment)
    {
        var runId = Guid.NewGuid().ToString();
        var startTime = DateTime.UtcNow;

        try
        {
            // Log parameters
            await LogParameters(runId, new Dictionary<string, object>
            {
                ["model"] = "gpt-4o",
                ["temperature"] = 0.7,
                ["max_tokens"] = 1000
            });

            // Run experiment
            var result = await experiment();

            // Log metrics
            await LogMetrics(runId, new Dictionary<string, double>
            {

                ["token_cost"] = result.TokenCost
            });

            // Log artifacts
