## Some List
* Train Set - Set used for training the ML model (For instance optimize the model parameters [For Parametric Model])
* Test Set - Set used to evaluate results.
* Prediction - Prediction of velocity given a measurement.
Implicit / Explicit Assumptions[^001]:
* The laser beam is eye safe.
* Just some information[^002].
### Some Existing Links
The results are pretty good in [RMSE][001] / [MAE][002].
## Some Text to Test
Free text, **bold text**, *italic text*, [__bold text__][003] or _italic text_.
Also, `Mono Spaced Text` and regular [boring text][04].
Some [Link](https://www.wikipedia.com) and [Reference Link][1].
Some list...
* Examining Deep Learning (DL) Based Methods
Always some text on [Deep][1] Learning.
* Hyper Parameters
Adding an exhaustive search of the optimal Hyper Parameters.
