Step 2: Data Collection & Preparation

  • Gather labeled datasets (e.g., user purchase history).

  • Clean data using Python’s Pandas:

    python
    Copy
    df.drop_duplicates(inplace=True)
df['text'] = df['text'].str.lower()  # Normalize text

Step 3: Model Training & Optimization

  • Train models using cloud platforms (Google Colab, AWS SageMaker).

  • Optimize for mobile with quantization (reduce model size).

Step 4: On-Device vs. Cloud-Based AI

  • On-Device: Faster, offline access (e.g., Face ID).

  • Cloud-Based: Handle complex tasks (e.g., ChatGPT API).
