Before diving into learning, it’s important to understand the basics. AI is the broader concept of machines mimicking human intelligence, while ML is a subset that focuses on enabling machines to learn from data and improve over time.
Key Differences Between AI and ML
| Aspect | Artificial Intelligence (AI) | Machine Learning (ML) |
|---|---|---|
| Definition | Simulates human intelligence | A subset of AI focusing on learning models |
| Goal | Create intelligent systems | Improve performance with data |
| Example | Chatbots, robotics, computer vision | Recommendation systems, fraud detection |
2. Identify Your Learning Goals
Why are you interested in AI and ML? Defining your goals will help you select the right path. Are you exploring AI for career opportunities, automating processes, or simply out of curiosity?
For instance:
- Career Development: Focus on building practical skills for job roles like Data Scientist, AI Engineer, or ML Developer.
- Personal Projects: Experiment with AI tools like ChatGPT or Python libraries to create fun projects.
- Academic Pursuits: Dive into theoretical foundations to contribute to AI research.
