OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Automatic Debiased Machine Learning via Neural Nets
Debiased machine learning based on regression requires estimation of an unknown debiasing function. We give an automatic method of estimating the debiasing function based on any machine learner. This method only depends on the parameter of interest and the machine learner. We give primitive regularity conditions for neural net estimation of the debiasing function and show its superior performance relative to inverse probability weighting in estimating the average treatment effect in a state of the art example.
