Description

Deep learning has been a sweeping revolution in the current world of AI and machine learning. It uses convolutional neural networks (CNNs) to help Teslas see the road properly; it uses reinforcement deep learning to help SpaceX land rockets automatically, and it uses recurrent neural networks (RNNs) to make machines translate better. The list goes on and on. But traditional industries may not see how this new, hot technology can help them.

Alex Liang details how the data science team at American Tire Distributors (ATD) uses machine learning solutions to rejuvenate the company. He used LSTM RNN models ensembled with fbProphet to generate staffing-level forecasts and further optimized with CVXPY for maximum optimality of staffing schedules. He also implemented deep neural nets as part of a pricing optimization pipeline, where DNNs are used for clustering as well as product demand modeling. The warehouse solution is now being used every day across the entire US in 140 distribution centers to cost-effectively staff more than 2,000 people daily and is on track to realize ~10% in labor cost savings and the pricing solutions are now being fully productionalized into the revenue management process, automating and optimizing pricing decisions for the majority of products. He outlines the overall business problem context, initial machine learning prototyping, resolving challenges in data and compute, and application automation. You’ll leave with key takeaways in developing this solution, including both technical and business lessons.

Prerequisite knowledge

  • General knowledge of deep learning
  • Experience with Python and data technologies (SQL, databases, and Hive)
  • Familiarity with cloud computing concepts

What you'll learn

  • Understand that any traditional industry can improve its business processes and create concrete values with open source technologies, cloud computing platforms, current cutting-edge deep learning, and AI techniques

Most AI talks are about applications in tech, software, ecommerce, maybe finance or health; but there are so many other industries, ripe for AI revolution. If you want to know how we apply deep learning solution in a traditional industry, come to this session. I will talk about the challenge we faced, both from data and business adoption, the solution we developed, and some other lessons and general thoughts about applying AI.

Implementing state of the art deep learning models is hard, put those models into production and scale up is harder, getting the business buy-in and put deep learning to generate real business value is even harder. And this is the main challenge faced by non-tech industries when applying AI. In traditional industries, data is messy, tech infrastructure tend to be outdated, and people’s mindset requires change, how do we apply cutting machine learning and push for business impact? Come to this session to find out.
