Scientific Computing runtime for VisualBasic.NET

sciBASIC#: A Microsoft VisualBasic feature runtime for data science application on Windows/Linux/macOS And China Tianhe Super Computing Platform. It was mainly consists with a data frame system, a data science analysis system, a data graphics system and a general application core runtime.

sciBASIC#(read as scientific visualbasic or just sciBASIC sharp) is a Microsoft VisualBasic language feature runtime for your data science application which is running in the CLI environment on Windows/Linux/macOS Desktop/Server platform or supercomputer platform. This framework project includes a lot of mathematics utility tools and the utility code extension functions for the data sciences application which is programming in VisualBasic language, and it also extends the VisualBasic programming language syntax. Makes the VisualBasic programming style more modernized in the data science industry by using this runtime library framework.

Abount VisualBasic code style guidelines:

https://github.com/xieguigang/sciBASIC/tree/master/docs/vb_codestyle

Guides for using this framework, you can found the document and content index at the README.md(This guidelines document is currently compiling for users):

https://github.com/xieguigang/sciBASIC/tree/master/docs/guides

Runtime Installation

Compile & Application Development on this runtime required the latest VisualStudio 2017.
If you are running sciBASIC runtime on Windows, please makesure your operating system supports .NET framework 4.6
If you are running sciBASIC runtime on Linux/macOS, please install mono runtime at first by following the installation manual on mono-project website. And then the Microsoft VisualBasic core runtime is required, you can find this runtime file in this repository: Microsoft.VisualBasic.7z, just extract this 7z archive and put the Microsoft.VisualBasic.dll kernel in the application directory.

Install this framework via nuget package

For .NET Framework 4.6:

https://www.nuget.org/packages/sciBASIC#

# For install latest stable release version:
PM> Install-Package sciBASIC
# For install latest unstable beta version:
PM> Install-Package sciBASIC -Pre

sciBASIC runtime can be split as two part: Part1 is the general application runtime, like scripting helper, commandline system, and text document parser; Another part of the runtime is the data science runtime, like math function, cluster function, or charting runtime for data visualization. All of the data science related namespace in sciBASIC are marked with asterisk.

FAQs

1. Which platform that I can using this framework? For writing x86/x64 server/Desktop Win32 CLI program.

2. Relationship between Microsoft VisualBasic.NET and sciBASIC? sciBASIC is fully compatible with the native VB.NET language, sciBASIC is a kind of dialect derive from the Microsoft VisualBasic.NET language.

3. Is there any interactive WinForm/WPF control for charting plot? One of this framework its primary target is aim at provides a drawing environment for your CLI program create high quality printable content for scientific manuscript. This framework is not too much involved with "interactive".

ODEs scripting language feature

Example for solving a dynamics system using VisualBasic ODEs scripting language feature, demo created for the Lorenz system:

Dim x, y, z As var
Dim sigma# = 10
Dim rho# = 28
Dim beta# = 8 / 3
Dim t = (a:=0, b:=120, dt:=0.005)

Call Let$(list:=Function() {x = 1, y = 1, z = 1})
Call {
    x = Function() sigma * (y - x),
    y = Function() x * (rho - z) - y,
    z = Function() x * y - beta * z
}.Solve(dt:=t) _

TextRank

PageRank analysis on the text paragraph for find out the keyword, here is the pagerank result of the this example paragraph:

"the important pagerank. show on pagerank. have significance pagerank. implements pagerank algorithm. textrank base on pagerank."

GraphQuery

GraphQuery is a query language and execution engine tied to any backend service. It is back-end language independent.

Imports Microsoft.VisualBasic.Data.GraphQuery
Imports Microsoft.VisualBasic.Data.GraphQuery.Language
Imports Microsoft.VisualBasic.MIME.application.json
Imports Microsoft.VisualBasic.MIME.application.json.Javascript
Imports Microsoft.VisualBasic.MIME.Markup.HTML

' define your graph query at here
Dim queryText As String = "..."
Dim query As Query = QueryParser.GetQuery(queryText)
Dim engine As New Engine
' http get of the html document text from web server or local filesystem
Dim url As String = "..."
Dim doc As HtmlDocument = HtmlDocument.LoadDocument(url)
Dim data As JsonElement = engine.Execute(doc, query)
' debug view of the graph query result
Dim json As String = data.BuildJsonString(New JSONSerializerOptions With {.indent = True})

Call Console.WriteLine(json)

sciBASIC Power the R# ggplot graphics library

The R# language is another scientific computing language which is designed for .NET runtime, R# is evolved from the R language. There is a famous graphics library called ggplot2 in R language, so keeps the same, there is a graphics library called ggplot was developed for R# language.

charting via R# ggplot

Another charting

Imports namespace for use the sciBASIC charting plot system api:

Imports Microsoft.VisualBasic.Data.ChartPlots

3D heatmap

Dim func As Func(Of Double, Double, (Z#, Color#)) =
_
    Function(x, y) (3 * Math.Sin(x) * Math.Cos(y), Color:=x + y ^ 2)

Call Plot3D.ScatterHeatmap.Plot(
    func, "-3,3", "-3,3",
    New Camera With {
        .screen = New Size(3600, 2500),
        .ViewDistance = -3.3,
        .angleZ = 30,
        .angleX = 30,
        .angleY = -30,
        .offset = New Point(-100, -100)
    }) _
    .SaveAs("./3d-heatmap.png")

Contour Heatmap

You can using a lambda expression as the plot data source:

Dim f As Func(Of Double, Double, Double) =
    Function(x, y) x ^ 2 + y ^ 3

Call ScatterHeatmap _
    .Plot(f, "(-1,1)", "(-1,1)", legendTitle:="z = x ^ 2 + y ^ 3") _
    .SaveAs("./scatter-heatmap.png")

Stacked Barplot

The stacked barplot is a best choice for visualize the sample composition and compares to other samples data:

Imports Microsoft.VisualBasic.Data.ChartPlots

' Plots metagenome taxonomy profiles annotation result using barplot
Dim file = "./FigurePlot-Reference-Unigenes.absolute.level1.csv"
' Using color brewer color profiles
Dim taxonomy As BarDataGroup = csv.LoadBarData(file, "Paired:c8") 

Call BarPlot.Plot(
    taxonomy,
    New Size(2000, 1400),
    stacked:=True,
    legendFont:=New Font(FontFace.BookmanOldStyle, 18)
) _
    .SaveAs("./FigurePlot-Reference-Unigenes.absolute.level1.png")

beta-PDF

Public Function beta(x#, alpha#, _beta#) As Double
    Return Pow(x, alpha - 1) * Pow((1 - x), _beta - 1) *
        Exp(lgamma(alpha + _beta) - lgamma(alpha) - lgamma(_beta))
End Function

Public Function lgamma(x As Double) As Double
    Dim logterm As Double = Math.Log(x * (1.0F + x) * (2.0F + x))
    Dim xp3 As Double = 3.0F + x

    Return -2.081061F - x + 0.0833333F / xp3 -
