This work follows previous results on Model Calibration (or Model Generation...) via Optimal Transport in various settings such as local volatility, local stochastic volatility, path dependent exotic products, VIX SPX calibration, and shows the versatility of this approach. 3/3

[EPSRC Random Systems CDT @CDTRandomSys]

CDT Student Benjamin Joseph, Jan Obloj @oxunimaths & Gregoire Loeper @BNPParibas have been working on model calibration via #OptimalTransport.

[EPSRC Random Systems CDT @CDTRandomSys]

They have addressed the case of calibration of equity products with stochastic rates, for which they give an exact calibration procedure. In their applications the resulting model is a local volatility model, where the state variables are the equity spot and the short rate. 2/3

Mental Health Awareness Week runs from 15–21 May.

Some events are now fully booked, but there are still plenty of opportunities to get involved. Don't forget to sign-up for daily tips emails.

Under 30% of STEM postgraduate research students identify as female. Our first Maryam Mirzakhani Scholar will address the M in STEM.

Marta joins us in the autumn. We look forward to many more. Thanks to @xtxmarkets for principal funding. #WomeninMaths

In the special case where the activation is the identity, we show that the equation reduces to a linear PDE and the limiting kernel agrees with the signature kernel (https://t.co/XLpQRlcv9o). (4/4)

Congratulations to first year CDT student Nicola Muça Cirone @ImperialMaths on their paper with @CristopherSalvi being accepted at #icml2023 (https://t.co/YlL7sOOUCb).

[EPSRC Random Systems CDT @CDTRandomSys]

these architectures converge weakly to Gaussian processes indexed on some spaces of paths and with kernels satisfying certain partial differential equations (PDEs) varying according to the choice of activation function. (3/4)

It's only 5 tweets since Oxford Mathematician Alison Etheridge was last elected member of an organisation. Luckily no-one remembers tweets for more than 5 seconds so we can confidently announce Alison has been elected member of the National Academy of Sciences. @theNASciences

Thanks to our keynote speakers Ilya Chevyrev, Ellen Powell, @eyal_neuman & @SamCMaths for sharing their research with us in a selection of excellent talks. Thanks also to @DesHigham for a hugely popular public talk on #DeepLearning (what could go wrong?) https://t.co/AG371sq1A5

[EPSRC Random Systems CDT @CDTRandomSys]

Thanks so much to all who took part in our 2023 Conference on Mathematics of Random Systems @ICMS_Edinburgh. We had excellent talks from our amazing students reflecting the broad range of topics in the CDT. The abstracts can be found on our website https://t.co/g2qTbLbmgg
