On the weekend of March 24–26, YCombinator-backed startup DeepGram hosted a deep learning hackathon. The weekend-long event included speakers and judges from Google Brain, NVIDIA, and... Read more
Visualising Similarity: Maps vs. Graphs
The visualization of complex data sets is of essential importance in communicating your data products. Beyond pie charts, histograms, line graphs and other common forms of visual communication begins the reign of data sets that encompass too much information to be easily captured by these simple...

Applying Deep Learning to natural language processing
Language is the medium that humans use for conversing. Giving machines the ability to learn human language with natural language processing has given rise to several new products and possibilities that were not previously imaginable. Natural language processing (NLP) is one of the most important technologies... Read more
How We Game the Algorithm to Tame the Algorithm
Algorithms are everywhere. Sometimes we see traces. Once in a while we feel the effects. Mostly, we go about our days vaguely aware of an invisible algorithmic presence. We set out to learn how people live with algorithms now and what it means for the future.... Read more
