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. AI is a broad field with numerous subfields, each with its unique objectives and specializations.

What are the different types of artificial intelligence?

As AI grows in popularity, the technology is discussed in various ways. 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

If you are new to this topic, you may also see the terms “machine learning,” “deep learning,” “data science,” and others creep into AI discourse. AI is a broad field with several subsets, including Machine Learning (ML) and Deep Learning (DL).

While there isn't an official definition for any of these terms, and while experts argue over the exact boundaries, there is a growing consensus on the broad scope of each term. 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.

Data science is a cross-disciplinary field that uses all of the above, amongst other skills like data analysis, statistics, data visualization, and more, to get insight from data.

You should also check out industry events, whether it’s webinars at DataCamp, data science and AI conferences, or networking events.

Develop a portfolio

A strong portfolio that showcases your skills and projects can make you stand out from other candidates. More importantly, a project attempting to solve a real-world problem will impress hiring managers.

As Nick Singh, author of Ace the Data Science Interview, said on the DataFramed Careers Series podcast,

The key to standing out is to show your project made an impact and show that other people cared. Why are we in data? We're trying to find insights that actually impact a business, or we're trying to find insights that will actually shape society or create something novel. We're trying to improve profitability or improve people's lives using and analyzing data, so if you don’t somehow quantify the impact, then you are lacking impact.

Nick Singh, Co-author of Ace the Data Science Interview

Your portfolio should contain a variety of projects that highlight your proficiency in key AI tools and algorithms. Check out our article on how to build a great data science portfolio for more information and tips.

Develop an effective resume

In today's digital age, your resume isn't just read by human eyes; it must also pass through Applicant Tracking Systems (ATS). These are automated software used by many companies to filter out resumes that don't meet certain criteria. Consequently, it's crucial to tailor your resume to be ATS-friendly while still catching the eye of hiring managers.

According to Jen Bricker, former Head of Career Services at DataCamp:

60% to 70% of applications get shifted out of consideration before humans actually look at the application.

Jen Bricker, Former Head of Career Services at DataCamp

As such, it’s extremely important to structure resumes as effectively as possible. You can read more about building a stand-out data scientist resume in a separate article.

Get noticed by hiring managers

Being proactive on social platforms can help attract the attention of hiring managers. As Sadie St. Lawrence, CEO of Women in Data, points out on the DataFramed Careers Series, sharing your projects and ideas on LinkedIn or Twitter, engaging with AI communities, and contributing to open-source projects can increase your visibility and showcase your passion for AI.

If you want to be seen, then you have to share your work. The analogy I like to use is a music box. If you've ever seen a music box, when it's closed and just sitting on the table, you never actually get to hear what the beautiful sound is inside of it. It’s similar for data scientists that lack communication skills. They may have these amazing skills, but they're all locked in this box, and no one ever knows about them. You have to open the box, and you do that by being able to tell those stories and communicate those skills. So, it's really up to you. Do you want people to hear your story and experience your amazing skills and ability? Then you're going to need the communication skills so that you can open your box.

Sadie St. Lawrence, CEO of Women in Data

Remember, breaking into AI takes persistence, continuous learning, and patience. But with these steps, you're setting yourself up for success. Good luck with your AI journey!
