ABOUT THE TALK

As a Real Estate aggregator, we deal with huge amounts of data: our crawler processes 6M ads/mo from 10k sites. In addition, the information on the source site is usually poor: many ads have no address, price, or description; but we can enrich this thanks to technology.

Taking noisy data, we make it great with machine learning.

In this talk, we will discuss 5 ways we use AI/ML to improve user search experience:

- Offering new ways of filtering. Our cutting-edge Convolutional Neural Networks make it possible to recognize images, detect watermarks and even evaluate apartment renovation quality.

- Boosting deduplication to 99% accuracy. We have developed our own technology for duplicates detection, which is now being patented, and we will explain how we have created it from scratch.

- Predicting price for poorly filled ads. Algorithms based on gradient boosting (GBM) over decision trees predict property price with 92% accuracy, and spam prevention systems work with 96% F1 score.

- Enriching ads with accurate address and parameters. RNNs help us determine crucial information that is often missing from the source ad, such as the apartment's exact address, area, room count, floor and other features.

- Enhancing images. We've constructed GANs that can remove almost any watermark or logo from images so users can properly view them.
