Mobipaleo is a tool that allows to extract frequent complex co-variations of the form "plus/minus a1, ..., plus/minus an" between numerical attributes in a database.
These co-variations of attributes called "gradient patterns" play a key role in many real-world applications where the volume of digital data to be managed is large, such as ecological, biological or medical data.


To use MOBI-PALEO, you must first register before login. Once logged in, you can submit a task via an available form.
Three parameters must be provided:

Task file

The dataset must be a simple text file with the extension .dat. The number of lines represents the total number of objects except for the first line which contains the names of the different attributes. The other lines give the values of each object on each attribute.


 a1   a2   a3 
 22   1200   4 
 24   2300   2 
 30   2700   3 
 28   3000   1 
is a valid dataset with 3 attributes and 3 objects.

The task frequency

The support (frequency) of a pattern indicates how important (its weight) is in the dataset. It is advisable to indicate a weak support to avoid extracting only generalities, then reduce the number of patterns in post-processing by filtering on the results.

Output file

The result files (.csv) have the following format:

Example of a result file:

 a1+   a2+   3 
 a1+   a2+   a3+   2 
 a1+   a2+   a3-   3 
 a1+   a2-   a3+   2 
 a1+   a3+   2 
 a1+   a3-   3 

The pattern a1+ a2+ a3- indicates that
