Data Cowboys is a boutique data science and machine learning consulting cooperative, offering custom expert-level solutions for complex data problems. We have over a decade of academic and real-world experience in turning challenges into practical algorithms using a battery of machine learning, artificial intelligence, data science, and statistics tools, and we take pride in clearly communicating our results to audiences of all backgrounds.
Services provided include applications of deep learning techniques (convolutional networks, recurrent networks, attention mechanisms, adversarial training, etc) to problems in computer vision, natural language processing, decision-making under uncertainty, and other applications. We’re also particularly well-versed in deep learning libraries such as TensorFlow and PyTorch, and we can develop code that can be used practically in future projects.
"We've really enjoyed working with Data Cowboys. I have explained our startup to hundreds of people and to this day Sergey and Ilya grasped what we do the fastest. Within minutes, our first conversation transitioned from context to idea generation, and it has been the same for every meeting since. They are professional, timely, and have a great sense of humor to boot. And they are so fast - both with their thinking and their output! Thanks to their efforts we have not yet had to hire data scientists in-house, saving us lots of money as well."

"Sergey's machine learning consulting expertise has been invaluable to us at RichRelevance. He has a wonderful knack for quickly scoping a problem, alighting on a suitable machine learning solution, making efficient and early decisions on model choice and parameters, analyzing data, implementing solutions, and clearly communicating throughout the process. His solid grasp of Bayesian statistics, deep neural networks, online learning and optimization etc, and his ready and speedy application have produced significant and concrete value for us on many occasions."
Apu Mishra, Lead Data Scientist, RichRelevance
"Sergey has helped me with the writing of two books about data analytics: Data Driven and The Data Driven Leader. He's easy to work with, and provides well-considered and well-written results very quickly. While helping me with the technical aspects of my books, he consistently exhibited in-depth knowledge of analytics, machine learning, and data science, and he has the rare ability to communicate that knowledge clearly to readers at every level. I would be happy to recommend him to anyone requiring machine learning services of any kind."

"Sergey Feldman is the ideal combination you want in a consultant: he’s brilliant, knows his subject matter inside and out, and is great to work with – collaborative, candid and funny. He’s also typically lightning-fast, a straight shooter and accepts feedback readily and with grace. He also has a special gift for explaining complex analytical and other concepts in terms anyone can understand. I’d hire him again in a heartbeat, with total confidence that he will shine, get the job done right the first time and make me look great."

"The work Data Cowboys has done to support our anti-trafficking efforts has been incredible. We are not only able to confidently understand and share the data generated by the work that we do, we're also able to verify that we're having the impact we intend - to keep people safe from exploitation. Sergey is responsive, thoughtful, and a tremendous asset to our mission."
