  15. 15. PHP ML - Other features Clustering (K-means algorithm). Similar to SV Classification method. The main difference of this method is detecting new areas. Metrics. Provides probability score. We can get the value of chance the some results is present in the data set. Pipeline. Allows to use multiple algorithms in the sequence. In other words you can make calculation in the queue. Neural network (MLPClassifier). Advanced classification feature. It is much more slower. Datasets. A base class for handling input data. PHP Array, CSV, TXT and SVM files are able from the box.
  16. 16. PHP-ML Disadvantages. PHP PERFORMANCE!!! Arkadiusz Kondas is working on the lib practically alone. Algorithm c4.5/5.0 (Classification and Regression Tree) is not implemented. We should use Pipelines + SVR/SVC but it is not very comfortable. Some major parameters of algorithms are dropped. For example lift() in the Apriori
  17. 17. Alternatives
  18. 18. Acquia Lift Cвiй, рiднесенький! Module is available on drupal.org Expensive. Used algorithms are not published. Indeed we have API only.
  19. 19. TensorFlow Free Flexible. Supports google cloud machine learning support is present (paid subscription). Has JS fork. Complex Don’t have PHP support.
