Append an existing model

[sonalmahajan01]

Hi,

Can we somehow read an existing model and append to it?

Thanks and Regards,

If you add a new document to a existing data source, and then set the model to unprepared $model->setPrepared(false); then when you try to classify something it will regenerate the model. But no there isn't a way to append to an existing model without recomputing.

Hi,

Thanks for the prompt reply. Actually my requirement was to generate model using a document records. and then based on scenario change, append another document records to the same model so i don't have to store all the files used for creating the model.

Any way this can be done with the current version?

Thanks and Regards,

I don't think that option is available at the moment sorry :(

Hi,
One more question related to the above question. Can we use multiple models for classification of a document? Like for loading classifiers:
public static function Factory($files){
if(empty($files) || count($files) != 1){
throw new \Exception("No file to load");
}
$classifierfile = $files[0];
if(!is_file($classifierfile)){
throw new \Exception("unable to find .model file!");
}
$fp = fopen($classifierfile, "r");
$content = fread($fp, filesize($classifierfile));
fclose($fp);

$classifier = unserialize($content);
unlink($classifierfile);
return $classifier;

}
Cause the parameter is $files, can i send an array of files and loop through them and read them. In that case ho do i deal with $classifier = unserialize($content);

If this can somehow work, then we dont need to append a model but use multiple models to classify a document.

Many thanks,
Sonal
