How to Learn AI From Scratch in 2024:

Artificial intelligence, or AI, is technology that enables computers and machines to simulate human intelligence and problem-solving capabilities.

Today, the term “AI” describes a wide range of technologies that power many of the services and goods we use every day – from apps that recommend tv shows to chatbots that provide customer support in real time.

In this article, you’ll learn more about artificial intelligence, what it actually does, and different types of it.

What is Artificial Intelligence (AI)?

• AI, or Artificial Intelligence, is a branch of computer science focused on creating systems that can perform tasks that would normally require human intelligence.
• These tasks range from understanding natural language, recognizing patterns, making decisions, and learning from experience.

What are the different types of artificial intelligence?

To simplify the remainder of the article, it’s important to look at the different types of AI. AI can be categorized into three levels based on its capabilities:

• Artificial Narrow Intelligence (ANI): This is the most common form of AI we interact with today. ANI is designed to perform a single task, like voice recognition or recommendations on streaming services.
• Artificial General Intelligence (AGI): An AI with AGI possesses the ability to understand, learn, adapt, and implement knowledge across a wide range of tasks at a human level. While large language models and tools such as ChatGPT have shown the ability to generalize across many tasks—as of 2023, this is still a theoretical concept.
• Artificial Super Intelligence (ASI): The final level of AI, ASI, refers to a future scenario where AI surpasses human intelligence in nearly all economically valuable work. This concept, while intriguing, remains largely speculative.

The difference between data science, artificial intelligence, machine learning & deep learning:

AI is a broad field with several subsets, including Machine Learning(ML) and Deep Learning (DL).Here’s a breakdown of how these terms can be defined:

• Artificial intelligence refers to computer systems that can behave intelligently, reason, and learn like humans.
• Machine learning is a subset of artificial intelligence focused on developing algorithms with the ability to learn without explicitly being programmed.
• Deep learning is a subset of machine learning. It is responsible for many of the awe-inspiring news stories about AI in the news (e.g., self-driving cars, ChatGPT). Deep learning algorithms are inspired by the brain's structure and work exceptionally well with unstructured data such as images, videos, or text.

Learning AI can be an exciting endeavor, but it’s not without its challenges. However, with a clear roadmap, the right resources, and a strategic approach, you can navigate this landscape effectively. Here’s how to learn AI in 2024:

1. Master the prerequisite skills:

These foundational skills will form the backbone of your AI understanding and capabilities:

• Basic mathematics:

AI relies heavily on mathematical concepts, particularly its subfields like machine learning and deep learning.

Basic understanding of linear algebra, calculus, and probability is essential. For instance, concepts such as matrices and linear transformations from linear algebra are frequently used in AI algorithms.

• Basic statistics:

AI makes a lot of sense when you understand statistics. Concepts like statistical significance, distribution, regression, and likelihood play a significant role in different AI applications.

• A willingness to learn:

A proactive mindset and an enthusiasm for learning and adapting to new knowledge and technologies are pivotal for anyone looking to break into and advance in AI.

2. Develop specialist AI skills:

Let's delve into the essential skills you need to develop to master AI. Similar to the prerequisite section above—the level of mastery you’ll need for these skills largely depends on what type of role you wish to pursue.

Statistics:

• Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. It provides the backbone for understanding and working with data in AI.
• The four fundamentals of statistics using Python, including summary statistics and probability, statistical models such as linear and logistic regression, techniques for sampling, how to perform hypothesis tests, and draw conclusions from a wide variety of data sets.

Mathematics:

• As discussed earlier, certain areas of mathematics form the foundation of AI algorithms.
• Linear algebra, calculus, probability, and differential equations are all mathematical tools that will be used in your AI journey.

Programming:

• AI implementation requires a sound understanding of programming.
• Knowing how to write code allows you to develop AI algorithms, manipulate data, and use AI tools and libraries.
• Python is currently the most popular language in the AI community due to its simplicity, flexibility, and availability of data science libraries.

Data structures:

• Data structures allow you to store, retrieve, and efficiently manipulate data.
• Therefore, knowledge of data structures like arrays, trees, lists, and queues is essential for writing efficient code and developing complex AI algorithms.

Data manipulation:

• Data manipulation involves cleaning, transforming, and manipulating data to prepare it for further analysis or feeding it into AI models.
• Skills in using libraries like pandas for data manipulation are essential for working in AI.

Data science:

• Data Science is a blend of various tools, algorithms, and machine learning principles aimed at discovering hidden patterns from raw data.

Machine learning:

• Machine Learning is a subfield of AI where machines learn from data to improve their performance or make accurate predictions.
• It's essential to understand different machine learning algorithms, how they work, and when to use them.

Deep learning:

• Deep Learning, a subset of machine learning, uses neural networks with multiple layers (hence 'deep') to model and understand complex patterns in datasets.
• It's behind many of the most advanced AI applications today, from voice assistants to self-driving cars.

3. Learn the essential AI tools and packages:

Knowing the right tools and packages is crucial to your success in AI.
