+MADlib v1.14:
+
+Release Date: 2018-April-28
+
+New features:
+* New module - Balanced datasets: A sampling module to balance classification
+ datasets by resampling using various techniques including undersampling,
+ oversampling, uniform sampling or user-defined proportion sampling
+ (MADLIB-1168)
+* Mini-batch: Added a mini-batch optimizer for MLP and a preprocessor function
+ necessary to create batches from the data (MADLIB-1200, MADLIB-1206,
+ MADLIB-1220, MADLIB-1224, MADLIB-1226, MADLIB-1227)
+* k-NN: Added weighted averaging/voting by distance (MADLIB-1181)
+* Summary: Added additional stats: number of positive, negative, zero values and
+ 95% confidence intervals for the mean (MADLIB-1167)
+* Encode categorical: Updated to produce lower-case column names when possible
+ (MADLIB-1202)
+* MLP: Added support for already one-hot encoded categorical dependent variable
+ in a classification task (MADLIB-1222)
+* Pagerank: Added option for personalized vertices that allows higher weightage
+ for a subset of vertices which will have a higher jump probability as
+ compared to other vertices and a random surfer is more likely to
+ jump to these personalization vertices (MADLIB-1084)
+
+Bug fixes:
+ - Fixed issue with invalid calls of construct_array that led to problems
+ in Postgresql 10 (MADLIB-1185)
+ - Added newline between file concatenation during PGXN install (MADLIB-1194)
+ - Fixed upgrade issues in knn (MADLIB-1197)
+ - Added fix to ensure RF variable importance are always non-negative
+ - Fixed inconsistency in LDA output and improved usability
+ (MADLIB-1160, MADLIB-1201)
+ - Fixed MLP and RF predict for models trained in earlier versions to
+ ensure misisng optional parameters are given appropriate default values
+ (MADLIB-1207)
+ - Fixed a scenario in DT where no features exist due categorical columns
+ with single level being dropped led to the database crashing
+ - Fixed step size initialization in MLP based on learning rate policy
+ (MADLIB-1212)
+ - Fixed PCA issue that leads to failure when grouping column is a TEXT type
+ (MADLIB-1215)
+ - Fixed cat levels output in DT when grouping is enabled (MADLIB-1218)
+ - Fixed and simplified initialization of model coefficients in MLP
+ - Removed source table dependency for predicting regression models in MLP
+ (MADLIB-1223)
+ - Print loss of first iteration in MLP (MADLIB-1228)
+ - Fixed MLP failure on GPDB 4.3 when verbose=True (MADLIB-1209)
+ - Fixed RF issue that showed up when var_importance=True with no continuous
+ features (MADLIB-1219)
+ - Fixed DT/RF issue for null_as_category=True and grouping enabled
+ (MADLIB-1217)
+
+Other:
+ - Reduced install-check runtime for PCA, DT, RF, elastic net (MADLIB-1216)
+ - Added CentOS 7 PostgreSQL 9.6/10 docker files
