Nonregular event: Data Science at Booking

Leave a comment

We are pleased to announce the following event, sponsored by Booking.com and in collaboration with Gemleb. In this session, people from Booking.com will explain us what kind of problems they deal with related to data science and machine learning (the talks may be more technical oriented than usual).

1) Data Science: For Fun and For Profit

Data Science is relatively new, but the ideas and techniques that form the underpinnings for this evidence-oriented discipline have a solid foundation in hundreds of years of scientific development. In order to understand the new science of data, one must first understand the science of science.
The Scientific Method, the unintended effects of repeated significance testing and Simpson’s paradox: this talk will focus on the practical applications of the theoretical constructs that lie at the heart of Data Science; and expand on some potential pitfalls of statistical analysis that you are likely to encounter when venturing into the field.

Lukas is an experienced data science professional with a background in computing science and online machine learning for real time decision support. A strong advocate of “Evidence-Based Everything”, he is forever learning and helping machines do the same. As a Data Scientist at Booking.com, the world’s leading accommodation website, Lukas is exploring novel ways to make booking hotels online into a more personal experience.

2) Topic Modelling on Travel Data.

Booking.com collects millions of diverse endorsements from its users, for example, London endorsed for Shopping, Brussels for Chocolate, Athens for Museums and Barcelona for its nightlife. These endorsements are organised using Latent Dirichlet Allocation to a set of topics and used to personalise the Email-Marketing campaign of Booking.com. The results from experiments on more than 40 million unique users demonstrate the conceptual value of the discovered topics.

Athanasios Noulas completed his PhD in Machine Learning in the University of Amsterdam where he focused on Dynamic Bayesian Networks and Deep Learning. He then worked as a strategist in Source Capital where he developed algorithms for high frequency automated training. He is currently working for Booking.com as a Data Scientist in the Visitor Profiling team, where he performs analysis on user-behaviour and implements algorithms that adjust the web-site to the user’s needs.

At the end we will have some drinks and time for networking.

Personalization in CRM event review

Leave a comment

On March 9th, 2015 BCNanalytics was proud to host its second conference, “Personalisation in CRM”.

  • 198 people registered
  • 165 people atteneded
  • 83 empty beer bottles by the end of the event

The event was hosted at the Mobile World Centre and was attended by people representing  industries like banking, e-commerce, consulting, gaming, fashion, telecom, as well as academia and independent entrepreneurs.

To start off the event we had Manuel Bruscas, co-founder of BCNanalytics, present some of the key news of our organisation, like the creation of a job board on our site and some of the potential events we would like to organise like a hackathon or workshops.

Manuel presenting

We had Pau Agulló, also co-founder of BCNanalytics, introduce our two keynote speakers and later serve as moderator during the Q&A session.

Pau presenting speakers

Our first speaker was Pier Paolo Rossi, current director of Business Intelligence at Banc Sabadell. Pier Paolo’s presentation covered a wide range of examples coming from his multi-industry experience having worked in telecomms (Movistar), retail (Caprabo) and lately banking (Banc Sabadell). He showed how personalisation can be applied to pricing, product, information layout and other areas of your business to expand the lifetime engagement and experience of your customers. His talk highlighted two points we would all do well to remember: “you can’t manage what you can’t measure” and “your customer is the most important thing”.

Pier Paolo Rossi

Our second speaker was Llorenç Solà, Director of CRM and Customer Strategy for Vistaprint Europe. Llorenç explained us that using personal content in communication wins over non-personalised approaches because it allows a business or organization to become more relevant to their users. He also reminded us that appropriate personalisation is by no means easy to achieve, since it always involves: data storage, analysis, statistical modelling and a user friendly strategy around frequency of touch points. There was particular emphasis given on the last point applied to email practices. In his opinion if long term performance is desired then email campaigns should not be measured simply by gross revenue. That would only lead to the controversial practice of mass emailing, which can arguably degrade your ability to communicate and influence your customers. Instead performance should be measured by the efficiency by which you get customers to interact with your communication.

Llorenç Solà

After the presentations our keynote speakers formed a panel and we discussed what had been presented. The audience was actively engaged with many questions for our presentors. Regarding the role of privacy in personalisation, one opinion was that if done right, personalisation is welcomed by customers. When asked which channel to use for communication the answer was that you should make your customer choose the channel for communication that they want. Other questions addressed the role of people and technology, as well as further discussion on the impact of limiting the amount of emails sent to customers in favor of more personalised content.

The conference closed with a networking event with free beers provided by our sponser Estrella Damm. People took this opportunity to ask further personal questions to our keynote speakers as well as meet fellow members of Barcelona’s analytics community. Thank you all for making this event a success. Please help us decide on our next event as well as ideas for other events by filling out this survey.

Beer time!!

Visualizing Barcelona’s Public Bikes Usage

Leave a comment

Did you know that Spain has the greatest number of bicycle sharing systems in the world? Having a high demand for these makes a lot a sense – the mild winter leaves one no bad-weather-excuses for not biking; and in the summer the bicycle is the most pleasant transport method for going to the beach. But if you have ever tried to go to the beach on the bici (that’s how the public bikes are called in Barcelona) on a lovely Sunday morning, you’ve probably stumbled on your closest station being empty. So you walk under the scorching Spanish sun to the next station, and quite possibly – to the one after that, until you can find a bicycle. Once you finally arrive to the beach, all the stations are now full, and there’s a line of people waiting to return their bicing.

Each time this happened to me, it got me thinking that there should be a way to forecast the demand in order to improve the supply. Fortunately, the guys at CityBikes have provided an API with the momentary availability of bikes. So, I scraped a several days worth of data, averaged the bikes per station and produced the following image.

bici

The white dots are the stations that are on average (almost) full and the reds are (again almost) always empty.
Great, but this doesn’t help at all with the forecast, because even though the station which is closest to my apartment is in yellow (meaning that on average there are bikes), it is always empty in the morning and always full at night. The obvious solution would be to average the bikes on each station by time of the day and then create an animation with that. And I did. Here’s the result, conclusions and R source code to generate it.http://www.nikefreerunshoesplus.com nike free shoes
