Top 3 Uses of Artificial Intelligence: PTSD, Music, and Art

AI is all around us… In your phone, computer, and even your car. Every year these AI systems get smarter, faster, and a little bit scarier. We created a list of our favorite AI Implementations that take computing to the extremes. Let us know your favorite by Tweeting or posting on LinkedIn using @CXO Nexus.

1. PTSD, Neuroscience, and AI

Researchers have found a way to detect PTSD in veterans using only a small sample of their voice and a computer.

Can you define AI? Merriam Webster says AI is “the capability of a machine to imitate intelligent human behavior.” But is it imitation when it surpasses our intelligent behavior?

PTSD, or Posttraumatic stress disorder, is a psychiatric disorder caused by traumatic experiences that cause disturbing thoughts, dreams, flashbacks, and many more symptoms. Currently, most diagnoses are determined by self-assessment. With 12% of the world population reportedly having PTSD, self-assessment and limited clinical diagnoses leave many cases unreported and not treated. But what if it didn’t have to be that way?

AI and machine learning are proving to be applicable in all aspects of our lives. PTSD is no different. Researchers used a basic Random Forest, a statistical machine learning technique, “learned” how to categorize people based on mathematical models and example data to determine who has PTSD.

Without getting too much into the nitty-gritty, this machine learning algorithm took audio recordings of 53 Iraq and Afghanistan veterans with PTSD and 78 recordings of veterans without PTSD. These recordings were then inputted into the same voice recognition software that was used to make Apple’s Siri. The audio recordings were then captured in smaller segments totaling 41,000 separate clips which were processed through the Random Forest algorithms.

With this new database of audio clips, the algorithm was able to detect a pattern in speech defined by a lifeless, metallic tone, that has been described by psychologists for years but never quantified.

Thanks to AI and machine learning, we now have a tool to detect PTSD in a matter of hours, from home, with only a smartphone and a short voice recording.

2. AI Music. The next Beethoven?

AI music startups are popping up everywhere and musicians are thrilled.

Is AI the next Beethoven? Well, not yet, but it’s coming!

Since 2017, an Australian AI music startup Popgun has been creating an AI system that can take a recording of a human piano player and respond with a melody that could come next. Within one year the AI system learned so much from this exercise that it could compose and play piano, bass, and drums at the same time.

Other startups have used AI to help musicians create music in a matter of minutes instead of hours of recording, hating it, rewriting, rerecording, and on and on. Other startups have created systems that let listeners create music they want to hear using certain parameters that they like.

While there hasn’t been a hit song created by AI, there has been big collaborations. Jukedeck worked with a Korean company, Enterarts, where the AI system created chord sequences that Jukedeck then took and recorded with human artists.

Since then, there have been many collaborations that use AI to create musical pieces. While AI isn’t creating hit songs, it is empowering musicians in a way that helps them create the music we love.

3. What Is Art? Robots think they know.

Artists are partnering with AI companies to create new takes on old art pieces and one of a kind pieces.


What is art? The highly admired author, Margaret Hungerford, would argue that “Beauty is in the eye of the beholder.” The owner of the algorithm-generated print, shown to the right, took this saying to heart. Through all of the controversy and the pricey tag, this anonymous person bought the print for $432,500 even though it had never been shown in galleries or exhibitions before coming to market.

A collaboration between Dr. Ahmed Elgammal and AI, named AICAN, has created an exhibit devoted to an AI artist. This team argues that art can be anything if it is new and surprising. This AI system, and others like it, takes thousands of art pieces and categorizes them to create a database to work from.

Art databases are nothing new, but once the AI system has this information, it can determine what makes these pieces unique and special. Taking all these inputs, the AI system creates something similar to the original with almost no input, or something unique with minimal input.

While some find this new and surprising, others claim these AI systems and their human counterparts are just stealing ideas, designs, and everything else. Critics say that an art piece created by a third party AI system, using art pieces they didn’t make, is not art.

Either way, advances in AI are extraordinary and give us a better idea of what is to come. Just like the AI system that can detect PTSD in minutes and the AI systems that can develop music, this AI system could one day create one of a kind art pieces custom made for you in minutes.
