We’re told data science is the key to unlocking the value in big data, but nobody seems to agree just what it is. Is it engineering, statistics. . .both? David Donoho’s “50 Years of Data Science”, which is itself a survey of Tukey’s “Future of Data Analysis”, offers one of the best criticisms of the […]
The huge flows of data enabled by social media, smart phones and the internet have created a revolution in the way we interact with events around the world, especially in the arena of conflict. This environment has given us access to information which can be used for investigative journalism, conflict analysis and the identification of […]
Word embeddings are a family of Natural Language Processing (NLP) algorithms where words are mapped to vectors in low-dimensional space. The interest around word embeddings has been on the rise in the past few years, because these techniques have been driving important improvements in many NLP applications like text classification, sentiment analysis or machine translation. […]
1st line of the technical support is frequently providing answers to FAQ and pre-assembled conversations for operators to follow. With the enhancements in A.I. and Machine Learning, how much of this task could be supported with the aid of software? While this raises many questions and challenges, the first would be how would software understand […]

“The model was working just fine two weeks ago, but now I can’t reproduce it!” “Bob’s on vacation – how do I run his model?” “Is my neural network useless or should I continue tweaking its parameters?” Have you ever heard any of the above before? We had the same problems when running research and […]
In this talk, we will explore the invisible side of visual data, investigating how machine learning can detect subjective properties of images and videos, such as beauty, creativity, sentiment, style, and more curious characteristics. We will see how these detectors can be applied in the context of web media search, advertising and social media. And […]
Search is a common feature for apps. The basic implementation of search as an information retrieval exercise does not allow for personalisation. A smart search, that boosts the information retrieval with sorting based on the relevance to an individual, adds to the user experience.
