LinPred(3) User Contributed Perl Documentation LinPred(3)NAME
PDL::Filter::LinPred - Linear predictive filtering
SYNOPSIS
$a = new PDL::Filter::LinPred(
{NLags => 10,
LagInterval => 2,
LagsBehind => 2,
Data => $dat});
($pd,$corrslic) = $a->predict($dat);
DESCRIPTION
A filter by doing linear prediction: tries to predict the next value in a data stream as accurately as possible. The filtered data is the
predicted value. The parameters are
NLags Number of time lags used for prediction
LagInterval
How many points each lag should be
LagsBehind
If, for some strange reason, you wish to predict not the next but the one after that (i.e. usually f(t) is predicted from f(t-1)
and f(t-2) etc., but with LagsBehind => 2, f(t) is predicted from f(t-2) and f(t-3)).
Data The input data, which may contain other dimensions past the first (time). The extraneous dimensions are assumed to represent
epochs so the data is just concatenated.
AutoCovar
As an alternative to Data, you can just give the temporal autocorrelation function.
Smooth Don't do prediction or filtering but smoothing.
The method predict gives a prediction for some data plus a corresponding slice of the data, if evaluated in list context. This slice is
given so that you may, if you wish, easily plot them atop each other.
The rest of the documentation is under lazy evaluation.

TriD::VRML(3pm) User Contributed Perl Documentation TriD::VRML(3pm)NAME
PDL::Graphics::TriD::VRML -- TriD VRML backend
SYNOPSIS
BEGIN { $PDL::Graphics::TriD::device = "VRML"; }
use PDL::Graphics::TriD;
use PDL::LiteF;
# set some vrml parameters
my $set = tridsettings(); # get the defaults
$set->browser_com('netscape/unix');
$set->compress();
$set->file('/www-serv/vrml/dynamic_scene.wrl.gz');
line3d([$x,$y,$z]); # plot some lines and view the scene with a browser
DESCRIPTION
This module implements the VRML for PDL::Graphics::TriD (the generic 3D plotting interface for PDL). You can use this backend either (a)
for generating 3D graphics on your machine which can be directly viewed with a VRML browser or (b) generate dynamic VRML worlds to
distribute over the web.
With VRML, you can generate objects for everyone to see with e.g. Silicon Graphics' Cosmo Player. You can find out more about VRML at
"http://vrml.sgi.com/" or "http://www.vrml.org/"
BUGS
Probably incomplete/buggy implementation of some TriD features.

i have folowing code.
i dont want data in an array. i like to put my data file info (after filtering and converting to lower case) in to a string call "name". so it would look like this,

Hi,
Please i'd like to use prediction techniques in sklearn
I have this file:
x | y
1| 1

--> prediction techniques must give me this model y=x*x
using this model i can predict the value y of x=3
This is a sample example. In my experiment i use a file with 1000... (3 Replies)
