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

Following the success of the previous tutorial on Machine Learning in Python, we organise another session on this topic. We will be covering other aspects of ML this time, so this Code Clinic can be attended as a follow-up from the previous ML Python session, as well as a separate independent session – everyone is welcome to join.
We will continue using scikit-learn Python library (scikit-learn.org).
Last time we went through the simple example of solving a classification problem using ML, while this time we will pay attention to the regression problem.
Additionally, we will learn about the feature selection methods, which allow reducing the overfitting and improving the accuracy of the predictions, and will apply feature selection to our dataset. Then, we will evaluate the performance of different regression algorithms via such metrics as Mean Absolute Error, Mean Squared Error, and R^2.
At the end of the session, we may discuss the differences between supervised and unsupervised learning problems and look deeper at the available algorithms for each type of data.
The following tools will be used in this code clinic:
Python3 – www.python.org
Python SciPy libraries:
scipy
numpy
matplotlib
pandas
sklearn (shorten from scikit-learn)
Irina Chelysheva will be working in Spyder IDE – www.spyder-ide.org, but, please, feel free to use your favourite one
