Overview

Gonum

Build status Build Status Build status codecov.io coveralls.io go.dev reference GoDoc Go Report Card stability-unstable

Installation

The core packages of the Gonum suite are written in pure Go with some assembly. Installation is done using go get.

go get -u gonum.org/v1/gonum/...

Supported Go versions

Gonum supports and tests using the gc compiler on the two most recent Go releases on Linux (386, amd64 and arm64), macOS and Windows (both on amd64).

Release schedule

The Gonum modules are released on a six-month release schedule, aligned with the Go releases. i.e.: when Go-1.x is released, Gonum-v0.n.0 is released around the same time. Six months after, Go-1.x+1 is released, and Gonum-v0.n+1.0 as well.

The release schedule, based on the current Go release schedule is thus:

  • Gonum-v0.n.0: February
  • Gonum-v0.n+1.0: August

Build tags

The Gonum packages use a variety of build tags to set non-standard build conditions. Building Gonum applications will work without knowing how to use these tags, but they can be used during testing and to control the use of assembly and CGO code.

The current list of non-internal tags is as follows:

  • safe — do not use assembly or unsafe
  • bounds — use bounds checks even in internal calls
  • cblas — use CGO gonum.org/v1/netlib/blas/netlib BLAS implementation in tests (only in mat package)
  • noasm — do not use assembly implementations
  • tomita — use Tomita, Tanaka, Takahashi pivot choice for maximimal clique calculation, otherwise use random pivot (only in topo package)

    fourier: new package for fourier analysis and related functions

    Please take a look.

    So far I have only added the backing code. I want to add CFFT[IFB] and then I will dismantle some of the array.go support (remove 1-based indexing and the linear support types). It makes sense to add the API in this PR, so suggestions welcome here.

    meta-issue: document deprecation of all old gonum/xyz repos

    (putting it there, feel free to redirect to the best place)

    we should clearly put on all the old gonum/xyz repositories' README.md that these repos are deprecated and that issues, PRs should be redirected at gonum/gonum.

    I don't think we clearly communicated this.

  • optimize: completely overhaul Global

    optimize: completely overhaul Global

    The previous implementation of Global was a minefield for incorrectly implementing global optimization methods. It was very difficult to correctly implement methods (both of the provided methods were incorrect), and the resulting code is very ugly. This commit switches to use channels to communicate, allowing a more clear ordering of concurrent code. This also enables better shutdown of methods.

    In addition to the main fix of Global, this refactors the two Global methods to use the updated interface, and makes some small improvements that were previously not possible. In addition, there are some small cleanups of Local to better match between the two calls.

    If anyone has been curious about what is meant by 'Don't communicate by sharing memory, share memory by communicating' this is it, and why.

    This is commit one of ~~two~~ three. The ~~second~~ final commit will add element-wise weights, after the API is otherwise settled.

    Possible considerations are adding a reset method to allow data/locality reuse.

  • floats: add SameScalars to compare two float64 values with NaN == NaN.

    floats: add SameScalars to compare two float64 values with NaN == NaN.

    What

    floats/floats.go has a function

    // Same returns true if the input slices have the same length and all elements
// have the same value with NaN treated as the same.
func Same(s, t []float64) bool {
...}

    I would like to add there a function SameScalars which does the same for scalar inputs:

    // SameScalars returns true if the inputs have the same value with NaN treated as the same.
func SameScalars(a, b float64) bool {
	return a == b || (math.IsNaN(a) && math.IsNaN(b))
}

    Rationale

    Such a function will be useful for unit testing functions which are expected to return NaNs for some inputs.

    Updated proposal

    Rename Same to AllSame (breaks code) and call the new function Same.

  • stat: ROC signature

    stat: ROC signature

    I came up with what I think is an improvement to the ROC function, in which the cutoffs are defined explicitly instead of the number of cutoffs n. This allows for unequally-spaced cutoffs, allows for all cutoffs to be used more naturally, and simplifies the code itself.

    Is this a good idea -- should I put a PR in for it, @sbinet @kortschak ?

    Also, I was thinking maybe ROC should output an error as well, instead of all the panic statements? Or is it appropriate that it panic?

    What I did is here, in case you wanted to look at the specifics of what I am suggesting: https://github.com/Armadilloa16/stat/tree/roc

  • graph/path: fix yen k-shortest path with root cycles

    graph/path: fix yen k-shortest path with root cycles

    Previously the code was not removing nodes on the root of the search path, resulting in searches that could re-enter previously searched nodes. In addition to this, the logic for making edges was incorrectly making both directions for digraphs and only one direction for undirected graphs.

    Finally, the range of nodes to include in the spur-node set was off-by-one. This is now clarified by including the comment from the wiki article since the pseudo-code is less clear than the English due to choice of range indexing convention.

    Please take a look.

    distuv NonCentralT

    What are you trying to do?

    The current implementation of the StudentsT distribution doesn't allow you to specify a non-centrality parameter ($\delta$). This would be useful because the noncentral-t distribution is useful for power analyses and in Bayesian inference (my personal usecase)

    Are you able to help contribute the feature?

    See #1819: I'm currently using translations I've made of R's nmath C library, and these translations could be used as the basis for this.
