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.
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.
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.
.csv) have the following format:
a1+ a2+ a3- indicates that
a1comes with an increase in the values of attribute
a2and a decrease in the values of attribute
3indicates that 3/4 of the objects in the dataset support this pattern.
