On my third day with Regency, I accompanied their project manager to a number of development sites, and we discussed some of the challenges he frequently encounters with developments. In one of his most recent projects, Midtown East, he encountered a number of serious unforeseen issues once construction had already started, all of which were challenging because they required involvement from the Department of Environment and Natural Resources. The first issue he encountered was the soil on the site was actually semi-toxic because there had been chemical pollution from a computer chip plant that had been there almost twenty years prior. The solution for this issue was to literally “get new dirt” which ended up costing nearly two million dollars, which was unforeseen. The second major issue encountered on this project was a culvert that ran underneath the site, which guided rainwater runoff into Crabtree Creek about half of a mile down the road. The culvert was far too small to handle all of the additional runoff from the new shopping center, so it had to be replaced, which made it into a City of Raleigh problem, but interestingly enough, the Regency was required to pay for it. The third issue with encountered with this development was the location of the retention pond for runoff. There wasn’t enough space for a traditional retention pond so they had to put it beneath the massive parking deck they were building. Ultimately, the project manager told me that the single most important part of big developments is allocated a decent chunk of money in the budget to unforeseen issues; it’s a win-win situation, because if it gets used you are on budget but if you don’t encounter any issues, you don’t have to spend it, and you are under budget.

Wrap Up With Dr. Laber
Today we had a brief meeting with Dr. Laber to wrap up these past few weeks and review our meetings with the Design Team and Mine Çetinkaya-Rundel. Additionally Dr. Laber talked about a project he is working on where he is hoping to make education more accessible especially at a University level.
Through this work experience I was able to get some insight on what it would be like to pursue statistics or AI in college and became exposed to concepts like reinforcement learning, respondent driven sampling and dynamic programming. I was also able to learn about the research his students were working on like the ethics of AI, Mount Boredom, and luck and skill in games.
Day 2 (5/27) How much should we really pay?
Regency Centers is a publicly traded commercial real estate company. They hold 395 mixed use developments across the United States, of which roughly 85% are grocery-anchored retail sites. So essentially, Regency acquires grocery-anchored centers and re-develops them or they acquire land and develop their own grocery-anchored centers. Ultimately, they are continuously doing similar projects, but the most important part of these projects is the profit, and the most important part of turning a profit is spending the right amount on the front end. There were multiple interesting tools that Regency uses to determine value of existing centers and prospective developments. One of the tools used to evaluate existing centers is called PLACER. PLAER is a data analysis application that uses cell phone data to determine many different things about shopping centers, and even specific stores. The app displays data collected from the phones of customers, with and almost alarming amount of personal information; it tracks where the customer travelled from, how old they are, the amount of money they spend in the center, the amount of time they spend in the center, how many times per month they visit the center, their race, and their annual income, just to name a few. The data is compiled in the app so that it can be easily interpreted to help predict profitability and therefore value. Another important evaluation tool, used for both existing and prospective developments, is Cap Rate, which is a monetary equation: Annual Net Income/Total Cost of Investment. This is one of the primary tools used to evaluate centers.
Day 6: James Grove Sales Team
After a great memorial day weekend, Mr. George decided to send me with the sales team for James Grove, the same development that I had been working with over the previous week. As seen in the featured image above, I worked with Haley and Stephanie, the sales team that was put in charge of selling James Grove. Typically, the sales team works out of a trailer built on site, however Haley and Stephanie will be resigned to a tent for the next month or so until the trailer is completed. While this made for a hot day, it was nothing short of eventful. There were 12 total appointments, where either Haley or Stephanie had to meet with the client and their agent to discuss the Lennar Offer Process and give them a detailed overlook of the available lots. The best part of today’s experience was having a fly-on-the-wall perspective of the conversations with the clients. Their reactions when we told them the starting bidding prices would be $515K (mind you, for a 2300 square foot townhome) was priceless on many occasions, however Haley and Stephanie both demonstrated incredible experience and professionalism addressing the clients concerns. While my initial interest at Lennar was land acquisition, I walk away from today knowing that sales is also something that I would enjoy tremendously.
6/2/21
Today was our final day. We started off by giving our presentation on how the company could effectively use applications like Teams and gave examples of how channels could be organized. We ended the presentation with a long Q&A, and hopefully, our suggestions helped to give the company a good overview of how Teams works. After that, we had a brief presentation on how the results of our email campaign went, and finally, we got to hear a presentation on how the company tracks its finances and they demonstrated some scenarios with made-up numbers. It was very interesting to see how these things are tracked, and we learned a lot about how many factors go into financial decisions in a company, especially when it’s a smaller business.
6/1/21
Today we started with a meeting where we learned about the behind-the-scenes aspect of business, and how a website is optimized to both contain accurate content but also have enough key search terms that it will show up early on Google. After that, we met one more time with our business development group to finalize the email that we were going to get to send out to Vascular Wellness’s potential partners in West Virginia. We gathered emails and sent the campaign out, and we will get to check the results tomorrow to see who opened the email and who clicked on the link to go to the website.
Day 1 (5/25) “Retail is theater” The creative side to development…
On my first day working with Regency Centers, we covered at great length multiple aspects of commercial development property management. Two aspects which I found particularly interesting were the visual element of mixed use commercial developments, and the Halo effect. To begin with the visual element of retail, I was told that “retail is theater” and that bad “theater” ultimately made for less success in retail. Essentially, storefront appearance is incredibly important because it makes customers feel special; it makes them want to shop. So, when regency develops new shopping centers, or when they acquire existing centers and re-develop them, a great degree of attention is given to the little visual details that enhance the shopping experience. I got to see this “theater” at work in Cameron Village, which is owned and managed by Regency Centers. The Halo affect was also an incredibly intriguing detail that I learned about. Essentially, the Halo affect is something that occurs with tenants in shopping centers, when one tenant will pay higher rent to be near a premium tenant. As it pertains to Regency Centers, they experience this very often with Whole Foods Market; retailers will pay higher rent to be next to a Whole Foods because it attracts affluent customers. Additionally, the Whole Foods will expect to pay lower rent because they are aware that other tenants will pay inflated rent in order to be in close proximity to them.
Improving Epsilon-Greedy: Q-Learning
Today was mostly a wrap-up session, but we were given some more time to explore topics of interest to us. I elected to spend some more time with RL, namely improving the epsilon-greedy algorithm explained in my last post. I decided to use the egreedy philosophy and apply it to a method of RL known as Q-Learning. Q-Learning is an algorithm where you take all the possible states of your agent, and all the possible actions the agent can take, and arrange them into a table of values (the Q-Table). These values represent the reward given to the agent if it takes that particular action while in that particular state. While they start at zero, the point of the algorithm is to accurately map and fill-in the Q-Table so that the most efficient (or close to it) series of actions is taken. The algorithm itself is pictured below
Most of these steps have been explained or are self-explanatory, however measuring reward is less intuitive. R is measured using what is known as the Bellman equation
As you can see, the Q value at a certain point in the table (state, action) is updated based on the reward given and a few other parameters specified by the user such as the learning rate (alpha) and the discount rate (gamma, how much we weight the short and long-term rewards). The action choice part uses the epsilon-greedy strategy I described in my previous post, however unlike the last post, epsilon starts at 1 and slowly decays throughout the training process. This makes it so that the algorithm can explore its choices to the fullest extent early on but as it does so, it becomes more sure of the best choices. I tested this algorithm on the taxi cab problem using software called OpenAI Gym, and as expected the rewards increased over time while epsilon decreased. I have had so much fun at this internship, and I hope to continue to explore AI and reinforcement learning in the future. Thanks for reading!
Ankle Fusions
Today I was at home because of Covid-19 restrictions at Duke Hospital. I spent the day researching the uses of ankle fusions. An ankle fusion is when a plate is surgically inserted at the ankle joint and the cartilage of the joint is removed. This causes the bones involved in the joint to grow together which will no longer allow for movement in the ankle. An ankle fusion is most commonly used when there is a serve injury to the ankle joint or there is arthritis in the ankle joint. For example, I met with a patient that had a gun shot wound to the talus causing massive amounts of damage in the ankle joint. The ankle was fused to allow for the talus to heal and to stop the pain that was being caused by a damaged talus. After an ankle fusion, the patient will no longer have a wide range of motion in their foot, however, they will still be able to walk and they will no longer be in pain.
The image above shows two different ways that the ankle can be fused.
Final Workday
Today was the final day for working on our projects. So far it looked really good and all things worked as they should. Today i was planning on adding many of the addons i made earlier last week like extra ammo and extra smoke grenades. Overall the game looked really good and i found that there weren’t any bugs that i found with the project. I also prepared for the presentations to other WEPs tomorrow by making a video that you can see below. Signing off Rohin.
