mh this was introduced to associate the correct lifetime for the kernel matrix [here](https://github.com/rust-ml/linfa/blob/master/linfa-svm/src/classification.rs#L174). We could copy the kernel matrix and avoid the lifetime there

in Elements of Statistical Learning the training vectors are sometimes called `predictors`, perhaps that's a better name than `records`

Good point! ESL uses predictors as a synonym for training data in the `Least Angle Regression` section and it should only be used for those features which are used in...

mh I wasn't aware of the Array2/Array1 implementation, but yeah I think it is not possible with the current trait system (though I'm absolutely not an expert there) the only...

a comment under the reddit post mentioned [polars](https://github.com/ritchie46/polars) and I'm now thinking about adding a dataframe type: ```rust pub type Dataframe = DatasetBase ``` observe the missing type on `polars::Dataframe`,...

the latter for example it makes no sense for ICA to support categorical features, but we could extend the scope of some algorithms with categorical types

you can write a transformer `f(Array) -> Array2` without dataframes, but would make handling strings easier

I investigated a bit and came up with these different dependency mismatches: * `cfg-if` caused by `reqwest`, opened an issue here https://github.com/davidMcneil/mnist/issues/7 * `generic-array` caused by `ndarray-npy` which we can...
