Recurrent Neural Networks: a suitable model for the brain?

Artificial neural networks (ANNs) form the architecture behind machine learning and artificial intelligence. These technologies are undergoing an explosion in use – from computer vision systems for self-driving cars and Snapchat filters, to voice recognition and big data processing for research. These algorithms are powerful because they effectively program themselves; they learn associations between input and output from large training datasets, and then apply this ‘knowledge’ to new situations. Computer vision, for example, is a complex problem that is incredibly difficult to write software for. It is hard enough for a computer to understand the outline of a cat against…

MedEthEx: Artificial Intelligence and Medical Ethics

MedEthEx is a prototype system developed by Michael Anderson, Susan Anderson and Chris Armen, to address the issue of ethics in medicine. The authors claim that the system can serve a vital educational role – both in and out of the clinic – and provide medical practitioners with the tools necessary to survive in the clinical setting, where such ethical dilemmas are bound to arise. Indeed, the system purports to guide medical practitioners through the hazy moral grey areas of medical ethics. Anderson, Anderson and Armen suppose that medical dilemmas arise due to a conflict of deep-rooted intuitions, or prima…

The RUMS Review: Back to the Beginning

A short interview with Rebecca Mackenzie, a fifth-year medical student and co-founder of the RUMS Review. What prompted you to establish the RR? The fact that a student magazine for the medical school didn’t already exist, which was crazy considering all of the amazing things going on in-and-around the medical school. It’s also lovely for alumni to see what current students are getting up to, as well as for current students to see the amazing things alumni have gone on to do. This provided the perfect platform! What was the most difficult thing about starting the RR? The easiest thing…

Prescribing Prevention

Dr Farrah Jawad is a registrar in Sport and Exercise Medicine.  She currently works at the Institute of Sport, Exercise and Health in London and co-ordinates the British Journal of Sports Medicine Trainee Perspective blog which can be accessed via http://blogs.bmj.com/bjsm/ .  She tweets at @FJSEM It has been said that exercise, if it were a pill, would be prescribed for almost everyone and would be one of the most cost effective interventions available.Low cardiorespiratory fitness has been shown to be a more important risk factor for all-cause mortality than hypertension, high cholesterol and smoking. One systematic review and meta-analysis…
