Dr Ekaterina Rogatchevskaia – ‘The Russian Revolution and the world today: exhibition and beyond’

Dr Katya (Ekaterina) Rogatchevskaia is the Lead Curator of the East European Collections in the British Library. She headed the organization of the Library’s exhibition “Russian Revolution: Hope, Tragedy, Myths’’ which commemorated the 100 year anniversary of the Russian Revolution.

During the meeting, Dr Rogatchevskaia guided us through the exhibition, beginning with its promoting poster. As she admitted, she did not initially like it, but the image used in 20th century by the Red Army for propaganda appeared to be powerful for modern spectators. Dr Rogatchevskaia vividly presented to us not only the history of the Russian Revolution, embodied in the British Library’s exhibits, but also the perception of the revolutions’ impact around the world. At the end of the meeting we could see fragments of Russian films from the first half of the 20th century and observe how those images – although stained with propaganda – managed to leave lasting and emotional impressions.

Jonathan Burn – How machines learn: writing a phone app to recognise birdsong

Jonathan Burn (OC) works in merchant bank IT and marketing. He is, in addition, a funk musician and mathematician, was a primary school teacher, and did a degree in Economics at the LSE in his own time for fun. He also has a masters in Artificial Intelligence from Imperial.
With an engaging and clear set of slides, Jon took us carefully through what sound is, how computers store the information contained in sounds, and how they can be set up to learn the best ways of identifying new sounds. This is done mainly through the ‘random forest’ technique: a way of generating questions to ask about a new sound which most accurately and efficiently put it into the right group (e.g. robin or blackbird).
