2. **Universe of Discourse Partitioning**: This is the most important step. Here, the range of values of the numerical time series *Y(t)* will be splited in overlapped intervals and for each interval will be created a Fuzzy Set. This step is performed by pyFTS.partition module and its classes (for instance GridPartitioner, EntropyPartitioner, etc). The main parameters are:
|
||||
- the number of intervals
|
||||
- which fuzzy membership function (on [pyFTS.common.Membership](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/common/Membership.py))
|
||||
- partition scheme ([GridPartitioner](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/partitioners/Grid.py), [EntropyPartitioner](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/partitioners/Entropy.py)[3], [FCMPartitioner](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/partitioners/FCM.py), [KMeansPartitioner](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/partitioners/KMeans.py), [HuarngPartitioner](https://github.com/PYFTS/pyFTS/blob/master/pyFTS/partitioners/Huarng.py)[4])

<span class="w"> </span><span class="sd">'''Sequence sorted by a key function.</span>
|
||||
|
||||
<span class="sd"> SortedCollection() is much easier to work with than using bisect() directly.</span>
|
||||
<span class="sd"> It supports key functions like those use in sorted(), min(), and max().</span>
|
||||
<span class="sd"> The result of the key function call is saved so that keys can be searched</span>
|
||||
<span class="sd"> efficiently.</span>
|
||||
|
||||
<span class="sd"> Instead of returning an insertion-point which can be hard to interpret, the</span>
|
||||
<span class="sd"> five find-methods return a specific item in the sequence. They can scan for</span>
|
||||
<span class="sd"> exact matches, the last item less-than-or-equal to a key, or the first item</span>
|
||||
<span class="sd"> greater-than-or-equal to a key.</span>
|
||||
|
||||
<span class="sd"> Once found, an item's ordinal position can be located with the index() method.</span>
|
||||
<span class="sd"> New items can be added with the insert() and insert_right() methods.</span>
|
||||
<span class="sd"> Old items can be deleted with the remove() method.</span>
|
||||
|
||||
<span class="sd"> The usual sequence methods are provided to support indexing, slicing,</span>
|
||||
<span class="sd"> length lookup, clearing, copying, forward and reverse iteration, contains</span>
|
||||
<span class="sd"> checking, item counts, item removal, and a nice looking repr.</span>
|
||||
|
||||
<span class="sd"> Finding and indexing are O(log n) operations while iteration and insertion</span>
|
||||
<span class="sd"> are O(n). The initial sort is O(n log n).</span>
|
||||
|
||||
<span class="sd"> The key function is stored in the 'key' attibute for easy introspection or</span>
|
||||
<span class="sd"> so that you can assign a new key function (triggering an automatic re-sort).</span>
|
||||
|
||||
<span class="sd"> In short, the class was designed to handle all of the common use cases for</span>
|
||||
<span class="sd"> bisect but with a simpler API and support for key functions.</span>
