Case Study: partnership between DataAi and Digital Catapult UK

Scoring of clients for subprime credit card

Problem: determine the probability that an applicant will default in the next 6 months to 1 year

Challenges: very high default rates, hundreds of variables,data inconsistency, poor statistics

Solution: We boost the accuracy by more than 30% and reduce losses by 18%

Technology: substantial pre-processing and data cleaning and classification with Random Forest

 

Churn prediction

Problem: based on CDR files (contact detailed records), to predict the probability of a customer to churn

Solution: we matched the accuracy of industry competitors (Kxen) with a less computational intensive approach

Technology: we used complex network analysis with weighted graphs to develop a diffusion model.

 

Customer segmentation

Problem: based on transactional data from credit cards, predict customer behaviours and categorisation.

Solution: we were able to predict when a customer will become inactive or travel abroad over the next 30 days.

Technology: Self-Organized Maps, Neural Networks and Random Forests algorithms.

 

Hotel demand prediction

Problem: Predict the demand of hotel bookings, occupancy rate and optimize the RPR.

Solution: we were able to predict the sales up to one month ahead with 89% accuracy.

Technology: Deep learning neural networks for time-series prediction corrected for seasonality effects based on historical data, competition and Google trends.

 

Image recognition and multimodal learning

Problem: based on facial images, determine emotional states and personality traits.

Solution: we developed an algorithm that achieves human level accuracy in a large database of 30 000 images.

Technology: Convolutional Neural Networks and Stacked Denoising Auto-Encoders
