LKJCholesky returns a Union

4

LKJCholesky causes type stability problems. MWE ```julia using Turing, Random @model function simple_model() F ~ LKJCholesky(2, 3.0) end model = simple_model() @code_warntype model.f( model, Turing.VarInfo(model), Turing.SamplingContext( Random.default_rng(), Turing.SampleFromPrior(), Turing.DefaultContext() ),...

PDMat on vector from arraydist fails with reversediff

3

I bumped into some more shenanigans with `reversediff` and covariance matrices. Generating a vector of numbers using `arraydist`, multiplying that with a matrix from LKJCholesky, and passing it back to...

Asssigning to a Vector of Matrices produces BoundsError

2

Sampling from `LKJ ` or `LKJCholesky` and assigning to a vector of matrices errors, regardless of AD backend. The code compiles but errors with a `BoundsError`. Sampling from the Prior...

Divergence from GLMnet when using a matrix with many variables

2

When fitting models with a large number of variables, Lasso.jl and GLMnet return different paths, and the difference grows bigger as the number of variables is bigger. An example to...

Memory leak when running GPU broadcast in a loop

6

I need to run GPU operations inside a loop, where the output of one iteration is used in the next one. However, even very simple GPU broadcasts result in a...

add constructor for binary classifiers

5

This PR adds a separate constructor `NeuralNetworkBinaryClassifier` for binary classification. Unlike for the existing `NeuralNetworkClassifier` constructor, in the final layer always has size 1. By default, a sigmoid function is...

precise step

3

An attempt to avoid the worst floating point errors when calculating step. @rafaqz let me know what you think about this heuristic

writing a Regular Intervals to netcdf produces Explicit Intervals

3

Writing a `Raster` to a netcdf and reading it back in again yields a `Raster` with `Explicit Intervals`, even if the raster originally had `Regular Intervals`. E.g. ```julia using Rasters,...

`cat` preserves metadata of first raster

1

A `Raster` created by concatenating multiple other `Raster`s keeps the `metadata` of the first `Raster`. Is that on purpose? MWE: ```julia using Rasters, RasterDataSources months = [4,5,6] rasters = map(m...

Plotting RGB Rasters with Makie

7

I used to be able to plot RGBA rasters with Makie using heatmap, but some recent version apparently broke this. I now get an error message that says ``` Makie...
