Hyperparameter Tuning and Model Performance Analysis

1. Define Objectives

1.1 Identify the Problem Statement

Clearly articulate the problem that the AI model aims to solve.

1.2 Set Performance Metrics

Determine the key performance indicators (KPIs) to evaluate model effectiveness, such as accuracy, precision, recall, and F1 score.

2. Data Preparation

2.1 Data Collection

Gather relevant datasets from reliable sources or generate synthetic data using tools like DataRobot or Google Cloud AI.

2.2 Data Cleaning

Utilize AI-driven tools such as Trifacta or Pandas for data wrangling and preprocessing to ensure data quality.

2.3 Feature Engineering

Implement techniques to create new features that enhance model performance using libraries like Scikit-learn or Featuretools.

3. Model Selection

3.1 Choose Algorithms

Select appropriate algorithms based on the problem type (e.g., regression, classification) using frameworks like TensorFlow, Keras, or PyTorch.

3.2 Initial Model Training

Train the initial model with default hyperparameters to establish a baseline performance.

4. Hyperparameter Tuning

4.1 Define Hyperparameters

Identify hyperparameters that significantly impact model performance, such as learning rate, batch size, and number of layers.
