Sparse columns

8

Should a dedicated API/column metadata to efficiently support sparse columns be part of the spec? ## Context It can be the case than a given column has more more than...

Currently we fix `n_iter`. I think we should instead implement some kind of stochastic convergence criterion (either on the training data or on held out validation split) and instead configure...

Unfortunately, I cannot see the `soda-inria/hazardous` repo from my codecov account at the moment (even after granting the permissions to codecov to access the `soda-inria` organization).

Measure GPU occupancy when running the benchmark on a Flex 170 on Intel DevCloud

4

vtune can be installed from the oneAPI basekit. Here is the command to record GPU statistics from the benchmark: ``` vtune -collect gpu-hotspots -- python kmeans.py --n-data-samples 5000000 --engine-providers sklearn-numba-dpex...

https://github.com/IntelPython/dpcpp-llvm-spirv should be available from the `dppy/label/dev` conda channel. It should be much lighter weight than the `"intel::dpcpp_linux-64"` we currently use as a dependency for `sklearn_numba_dpex`.

Make it possible to specify a given SYCL device programmatically

2

At the moment the only way to select a given device (cpu, gpu, with level zero or OpenCL or default host device) is via the `SYCL_DEVICE_FILTER` environment variable. It would...

Add array API support for Ridge(solver='cholesky')

4

Note: this PR uses `xp.linalg.solve` without being able to pass `assume_a="pos"` as is [possible in scipy](https://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.solve.html). As a result, the precise nature of the square matrix decomposition used to solver...

ENH fetch_file to fetch data files by URL with retries, checksuming and local caching

4

The goal of this helper would be to make it possible to have education examples that download and cache datafiles that are then manually loaded with functions such as `pandas.read_csv`,...

FIX TunedThresholdClassifierCV error or warn with informative message on invalid metrics

20

This PR fixes two usability problems with the new `TunedThresholdClassifierCV` when using it with invalid values for the `scoring` parameter: - the first case, is passing a scoring name or...

`dask.array` module should expose dtype objects and the `isdtype` function

```python >>> import dask.array as da >>> da.float32 Traceback (most recent call last): Cell In[5], line 1 da.float32 AttributeError: module 'dask.array' has no attribute 'float32' >>> da.isdtype Traceback (most recent...
