2. Key AI Concepts and Terminology

Machine Learning (ML)

• Definition: A subset of AI that enables systems to learn and improve from experience without being explicitly programmed.
• Key Formula: $Y = f(X)$, where $Y$ is the output, $X$ is the input data, and f is the function that maps inputs to outputs.

Deep Learning (DL)

• Definition: A subset of ML involving neural networks with multiple layers that can learn from vast amounts of data.
• Key Concept: Utilizes algorithms called artificial neural networks inspired by the human brain.

Neural Networks

• Definition: Computational models composed of interconnected nodes (neurons) that process information using dynamic state responses to external inputs.
• Key Formula: $y = \phi ( \sum_{i=1}^{n} w_i x_i + b )$, where $\phi$ is the activation function, $w_i$ are weights, $x_i$ are inputs, and $b$ is bias.

Natural Language Processing (NLP)

• Definition: AI's ability to understand, interpret, and generate human language.
• Applications: Language translation, sentiment analysis, and speech recognition.

Computer Vision

• Definition: Enables computers to interpret and make decisions based on visual data.
• Applications: Image recognition, object detection, and facial recognition.

4. Practical Commands and Azure Portal References

Setting Up Azure Machine Learning Workspace

1. Access Azure Portal: Go to Azure Portal.
2. Create Workspace:
   • Search for Machine Learning and select Workspaces.
   • Click Create and fill in required details (Subscription, Resource group, Workspace name, Region).
3. Configure Workspace:
   • Set up storage account, key vault, application insights, and container registry as needed.

Deploying a Machine Learning Model

Using Azure CLI Commands:

bash

# Install Azure CLI ML extension
az extension add -n azure-cli-ml

# Create a compute instance
az ml compute create --name my-compute --size STANDARD_D2_V2 --type AmlCompute

# Submit a training job
az ml run submit-script -c my-compute -e my-environment -s train.py

# Register the model
az ml model register -n my-model --file outputs/model.pkl

# Deploy the model
az ml model deploy -n my-service -m my-model:1 --ic inferenceConfig.json --dc deploymentConfig.json

Azure Portal Steps:

1. Navigate to Azure Machine Learning Studio.
2. Create Compute Resources: Under Compute, set up compute instances and clusters.
3. Upload Data and Scripts: Use Datasets and Notebooks sections.
4. Train Model: Use Automated ML or Designer for a visual interface.
5. Deploy Model: Under Endpoints, create a new deployment.

5. Memory Techniques and Mnemonics

Mnemonic for AI Concepts

"My Dog Never Needs Catnip"

• My (Machine Learning)
• Dog (Deep Learning)
• Never (Neural Networks)
• Needs (Natural Language Processing)
• Catnip (Computer Vision)

Story-Based Memory Technique

Imagine you're training your Dog to perform tricks (Machine Learning). As training progresses, your dog learns complex tricks (Deep Learning) by mimicking other dogs (Neural Networks). One day, your dog starts understanding your words (Natural Language Processing) and even watches TV with you, recognizing animals on the screen (Computer Vision).
