     "Consider a high-dimensional `space` whose `dimensions` are defined by the number of `features` (e.g. `10 features` would result in a space with `10 dimensions`. The resulting `volume` of this `space` is the amount of `samples` that could be drawn from the `domain` and the number of `samples` entail the `samples` you need to address your `learning problem`, ie `decoding` outcome. That is why folks say: \"get more data\", `machine learning` is `data`-hungry: our `sample` needs to be as representative of the high-dimensional domain as possible. Thus, as the number of `features` increases, so should the number of `samples` so to capture enough of the `space` for the `decoding model` at hand.\n",

     "This referred to as the [curse of dimensionality](https://en.wikipedia.org/wiki/Curse_of_dimensionality) and poses as a major problem in many fields that aim to utilize `machine learning`/`decoding` on unsuitable data. Why is that?\n",
