Wait! A Note on Registration:
We’ve launched Cvent—our new events platform!
Registration for any event with a start date after Sept. 28 now requires a CFA Institute account.
I don’t have a CFA Institute account
- No problem! You’ll have the chance to create one prior to registration.
I already have a CFA Institute account
- Great! Be sure to use your existing credentials at registration.
Initially we review the use of deep learning methods from image analysis and natural language processing applied to the problem of forecasting financial time-series. We extend these methods with state-of-the-art techniques from machine translation and thereby propose a novel multi-horizon forecasting model for limit order book data. Our empirical findings demonstrate that this new models outperforms existing methods significantly, however it is computationally expensive. We overcome this computational bottleneck by employing a cutting-edge hardware accelerator called an Intelligence Processing Unit (IPU). Our results demonstrate that IPUs can offer order of magnitude speed-ups compared with even Graphical Processing Units (GPUs) – the enabling technology that underpins the Deep Learning revolution of the last decade.
