##### ODE with R

Differential equations play an important role in biology, chemistry, physics, engineering, economy, and other disciplines. In R they can be solved numerically with a few lines of code, and several packages support solving them. We will demonstrate this with some easy, but interesting examples.

##### MLpackages

We will shortly repeat what we learned about the 'mlr3' package last year. A quick look at the 'mlpack' package and on AdaBoosting in general. Then there is 'tabnet', a package relying on PyTorch and providing deep neural network technology for tabular data.
