Hello MADlib users and developers, Now that the 1.9 release is out the door, I put up a candidate roadmap on the MADlib wiki https://cwiki.apache.org/confluence/display/MADLIB/Roadmap that I would like to get the community’s input on. It is also copied below in this email. This roadmap is roughly for the remainder of 2016.
Please feel free to share your thoughts on the proposal. It is based on the mailing lists, JIRA issues, pull requests, feedback from users, conferences ,etc. Predictive models Novelty detection using 1-class SVM https://issues.apache.org/jira/browse/MADLIB-990 Mixed effects modeling https://issues.apache.org/jira/browse/MADLIB-987 k-nearest neighbors (kNN) https://issues.apache.org/jira/browse/MADLIB-927 MCMC Probit and Logit regression Factorization machines Gaussian Mixture Model using Expectation Maximization (EM) algorithm Multi-layer Perceptron Geographically Weighted Regression (GWR) Graph Shortest path https://issues.apache.org/jira/browse/MADLIB-992 Standard traversal depth first search breadth first search topological sort One mode projection (converting a bi-partitite graph of user-item graph to user-user or item-item graph) Connected components Page rank Hierarchical graph cut Between-ness centrality Minimum spanning tree Utilities Path functions (phase 2) https://issues.apache.org/jira/browse/MADLIB-977 Prediction metrics https://issues.apache.org/jira/browse/MADLIB-907 Sessionization https://issues.apache.org/jira/browse/MADLIB-909 Pivoting https://issues.apache.org/jira/browse/MADLIB-908 Anonymization https://issues.apache.org/jira/browse/MADLIB-911 URI tools https://issues.apache.org/jira/browse/MADLIB-910 Stratified sampling https://issues.apache.org/jira/browse/MADLIB-986 Usability Expand coverage for PivotalR Expand coverage for PMML export Interface improvement and consistency Implement an interface using named parameters Python API Performance and scalability Work around PostgreSQL 1 GB field size limit https://issues.apache.org/jira/browse/MADLIB-991 Platform Support for PostgreSQL 9.5 https://issues.apache.org/jira/browse/MADLIB-944 The next release v1.9.1 is at the end of June, and the JIRAs so far targeted for this release are https://issues.apache.org/jira/issues/?jql=project%20%3D%20MADLIB%20AND%20fixVersion%20%3D%20v1.9.1%20ORDER%20BY%20summary%20ASC%2C%20key%20ASC%2C%20priority%20DESC I’d like to encourage us to get on a quarterly release cycle if at all possible.
