AI Awards
Winner of the $1M 2019 Zestimates prize
Nima was part of the team that won the $1M Zillow Prize for creating the most accurate home valuation algorithm.

The algorithm won by a comfortable margin, beating more than 3800 teams from 91 countries.

The teams's improvements will help push the Zestimate's current nationwide error rate of 4.5 percent to below 4 percent. The tool automates valuations on 110 million homes across the U.S.

Finalist in the Grupo Bimbo Inventory Demand Forecasting Competition
Nima ranked 7th in the Grupo Bimbo Inventory Demand Forecasting Kaggle competition against 1,969 teams. Before the model, Grupo Bimbo direct delivery sales employees made daily inventory calculations based on their personal experiences with each store. Our model accurately forecasted daily sales using historical sales data, product data, store data, and third party data such as weather to help Grupo Bimbo maximize sales and minimize returns in over 1M stores.

5th place in the IEEE BIG DATA Bosch Production Line Performance Competition
Nima was part of the team that placed 5th in the Bosch Production Line Performance Competition. Bosch challenged Kagglers to predict internal failures using thousands of measurements and tests made for each component along the assembly line. This enabled Bosch to bring quality products at lower costs to the end user.

It takes sizzling passion to win the most competitive data science competitions in the world. Students, event organizers, and event attendees can attest to the fact that Nima's passion comes across on the stage.

Whether speaking to experienced data scientists or to non-technical executives, Nima's obvious data-love-and-obsession captivates his audience, leaving them excited and curious about the future of Machine Learning.

Nima was selected as a speaker for ReWork 2018 Machine Learning Summit in Montreal where he presented on Demand Forecasting.

Nima also spoke at RBC Disruptors with a live audience of 500 and 174,000+ online views.

"Shahbazi has competed in 20 Kaggle events, coming second five times and finishing in the top 15 another five times. He finished in the top five per cent of challengers on contests for everything from a Grupo Bimbo (the Mexican bakery multinational that owns Dempsters, Hostess, Vachon brands in Canada) inventory algorithm, a Home Depot online search relevancy challenge, a drug store sales volume prediction engine, a music recommendation system and even the 2017 Data Bowl that looked at lung-cancer detection".

"Zillow has slowly improved its Zestimate from a median error rate of 14 per cent when it started in 2006 to 5.7 per cent when the contest began in mid-2017. It's now down to 4.5 per cent nationally (it's higher in some cities and lower in others), and once the winners' tweaks to the algorithm are incorporated, the company expects the error rate to dip to about 4 per cent".

"Jordan Meyer of the United States, Chahhou Mohamed of Morocco, and Nima Shahbazi of Canada bested more than 3,800 teams representing 91 countries with an algorithm that beat Zillow's benchmark model (evaluated against real-time home sales between August and October 2018) by approximately 13 percent."

"It's amazing to know that millions of people will benefit from our ideas," said Shahbazi, who competed as a team with Mohamed against Meyer in the contest's initial qualifier, but who decided to join forces with Meyer for the final round. "We brought every novel idea we could to our code and kept experimenting. For every idea that worked, there were a hundred that didn't work. But we kept going."
Zillow awards $1 million to team that reduced home valuation algorithm error to below 4%
On average, Zillow said, the Zestimate is $10,000 off the actual sale price for a median-priced home of about $223,900, and the information gleaned from the Zillow prize winnings could shave $1,300 off that discrepancy. It also moves the Zestimate's national median error rate below 4%.

"[the co-founders started Deepnify] to help food companies predict daily demand for their products, and reduce foot waste, by analyzing a mix of historic sales data and consumer trends.

"It's an important niche," Shahbazi says. "If you lower the waste, you can lower the price, which is good for the customers. More customers is good for the stores, and it's also environment friendly."

"Drug store giant challenged Kagglers to forecast 6 weeks of daily sales for 1,115 stores located across Germany. The competition attracted 3,738 data scientists, making it our second most popular competition by participants ever.
Nima Shahbazi took second place in the competition, using his background in data mining to gain an edge. By fully exploring and understanding the dataset, Nima was able to engineer features that many participants overlooked."
