Following the Scent of AI to Vienna

Written by: Katherine Sanders

Studying abroad in the spring gets cold quick. In the first weeks, every country we traveled to sat around 35F°. Walking around and admiring architecture was entertaining until the cold overwhelmed us. To escape into warmth while staying entertained, we retreat into Sephoras. At the Sephora in Prague, Baran wandered over to the perfumes while I swatched lip liners on my hand. Baran is picky when it comes to scent, so I went over with her and asked what makes a scent “good.” There’s different concentrations of elixirs… and some notes are better than others… but I still couldn’t grasp what makes a scent objectively great. 

Since my nose can’t pick up on the best scent for me, I let AI pick. Cosmotecha Vienna is a perfume shop located in Vienna. It’s run by EveryHuman, a company that creates personalized perfumes based on customers’ results to a personality quiz. With Baran’s love of perfume, my love of personality quizzes and our shared CS 3600: Introduction to AI class, this was the perfect activity for us to escape the Austrian cold.

Cosmotecha is a small, narrow space in the heart of the city. On the right, a sleek machine fills small viles with different liquids as the conveyor belt moves. Grey stools line the wall, seating customers as they complete the quiz and watch the machine. EveryHuman’s founder Frederik Duerinck says the machine is AI-enabled and learns how to create new scents with different ingredients. It understands what scents work well together, but takes liberties in creating new fragrances.

The personality quiz starts with multiple choice questions: words to describe your personal style, where you grew up (suburbs, city, countryside) and your hobbies. Then, there are questions similar to personality tests like MBTI. From not at all to very much, customers declare how much they relate with statements like, “is shy,” “easily distracted” and “is curious.” The quiz asked where we would rather be at that moment. The beach? The countryside? Baran and I chose the center of a bustling city. We didn’t want to be anywhere else.

Baran and I took our time answering each question. We added insight to make sure we both had a mix of our own personal vision and the perceptions from those around us. I usually think of myself as a dark, deep purple, but I’m more lavender than I thought. Baran is much friendlier than she thinks. The quiz ends by asking what scents we would enjoy in our fragrances. I chose to have more oud and musk and less citrus and fruit, but the machine had a different formula in mind.

Soon, three perfumes were created, boxed and handed to me. Spraying them on strips of paper, I was schocked. Each one was exactly how I wanted to smell. They weren’t just “fine” or “good,” they were right.

“636” is complex and grounding, reminding me of the luck I have; “audrey” is elegant and admirable; and “vitality” is youthful without smelling immature. While there was some intuitive reasoning behind the names for my scents, the main reason for their names was the reminders I needed. 

I cycle through each perfume now, reminded not just of their meanings but of the experience of exploring a friend’s passion.

A Day Pass for a Prague Pump

Written by Katherine Sanders

Maddie woke up on the night train with a nail missing. Ever since she learned how to do her nails in the summer, Maddie always has her nails long and painted. When she turned to me with her finger up, I knew it was going to drive her crazy. Prague, one of the cheapest cities in Europe, also has the cheapest manicures. Baran was enthusiastic about getting her nails done, too. 

Whenever I have nail polish on, I find a way to rip it off. Acrylics might be different since they can’t tear off easily, but I’d probably find a way. Although quite cheap, it wasn’t in my best interest to get my nails done. My other option was to stay at our hotel and get some work done. Homework? Homework… no. 

I made a list of gyms in Europe during winter break because I thought that one day I might need a day pass on a weekend trip. Today was the day. I searched up the gym, Form Factory, and found a location two minutes from our hotel. I went to street view on Google Maps and didn’t see a sign or a door, so I went to investigate when Baran, Maddie and I split up. I walked around a small strip mall for a couple minutes. Before giving up, I passed a girl my age also looking around, confused. I backed up and watched as she entered through a side door. I followed her. As she held the door open for me, she said something to me in Czech, to which I responded, “ahaha, yeah!”

I walked up two flights of stairs before reaching the front desk. She took my passport, email and phone number. She said, “Do you need a drink before your workout?” 

“Do I need to pay?” 

My day pass was free. I ran back to the hotel and changed into–don’t think I’m disgusting–one of my sleeping outfits. It was my only option. I only brought one pair of shoes for this trip: my Dr. Marten Mary Jane’s. My gym fit was definitely questionable. I got weird looks, but gains are gains. 

The weight lifting area was a small spiral staircase down from the main lobby. One side was for dumbbells, cables and machines. It had the usual: chest and shoulder press machines, a couple cables, leg extensions and a hamstring curl. The other side had benches, large leg presses, a smith machine and hip thrust. 

Back in the states, I had a strict routine I followed consistently. I split up my body into four sections: back and biceps; glutes, adductors and quads; chest, shoulders and triceps; glutes, hamstrings, abductors and calves. I lifted heavy weights and pushed until failure frequently which is hard to recreate without a gym. For glutes and quads, I can fill up my backpack with the heaviest items I have and perform step ups with a chair. For my chest, I can do deficit push ups. For biceps and shoulders, I can do movements with resistance bands. I took this time in Prague to do the exercises I never get to do. 

The machines in Europe are identical to the ones in the states. The only difference is the weights are exclusively in kilograms. In my head, I multiplied the numbers by two to get a rough estimate of how much I was lifting. The conversion from pounds to kilograms is actually 1lb to 2.205kg, so in the end I lifted much more than I thought. 

I stayed at Form Factory for about an hour. The five minute walk back to the hotel left me with time to clean up and relax. Maddie and Baran returned, showing off their new nails. The price was low for how well they came out. I hope they get their nails done again soon.
