Apple’s Siri. Google’s Google Assistant. Amazon’s Echo services.

These popular Artificial Intelligence applications have penetrated our everyday lives and made them more convenient, to say the least.

Artificial Intelligence is a myriad of technologies that enables 'intuitive' machines to offer human capabilities and imitate human intelligence. These automated tools can be trained to work as a human mind and comprehend, analyze, act, and evolve by using futuristic capabilities such as natural language processing, machine learning, data analytics, and voice recognition, among others. When AI technologies are integrated into a business setting, it can offer wide-ranging benefits. 

Why AI is Important: A Data-Driven Perspective

  • According to Accenture: "By 2035, AI can double economic growth rates in 12 developed countries and boost labor productivity by up to 40 percent." 
  • When used in conjunction with human effort, AI can allow people to spend more time on work that requires a human 'touch.' To put it in absolute terms, AI can take over 80% of the routine tasks and allow people to cater to the "20% of non-routine tasks that drive 80% of value creation."
  • Gartner predicts that "80% of emerging technologies will have AI foundations by 2021."

Clearly, AI is the future, and the future is here. 

What is Open Source Artificial Intelligence Software?

As complex as this sounds at the outset, these tools have increasingly become easy to use—thanks to engineers from tech giants such as Google, Facebook, and Uber, among others, as well as developers who routinely contribute to the open-source AI community and, thus, help churn out AI tools that characterize high-speed innovation.

More importantly, an open-source framework offers greater visibility into how developers 'think' and manage datasets and find patterns while keeping the feedback loop alive. All in all, relatively inexperienced professionals can leverage a constellation of AI tools, frameworks, libraries, and documentation and use these open-source artificial intelligence technologies for free.

With the right knowledge, even part-time data scientists can be successful, gaining confidence in the use of open-source AI tools and technologies to accelerate their projects and the projects of others.
