Scalable machine learning library for Hive/Hadoop

Hivemall: Hive scalable machine learning library

Hivemall is a scalable machine learning library that runs on Apache Hive. Hivemall is designed to be scalable to the number of training instances as well as the number of training features.

Supported Algorithms

Hivemall provides machine learning functionality as well as feature engineering functions through UDFs/UDAFs/UDTFs of Hive.

Binary Classfication

• Perceptron

• Passive Aggressive (PA, PA1, PA2)

• Confidence Weighted (CW)

• Adaptive Regularization of Weight Vectors (AROW)

• Soft Confidence Weighted (SCW1, SCW2)

• AdaGradRDA (w/ hinge loss)

• Factorization Machine (w/ logistic loss)

My recommendation is AROW, SCW1, AdaGradRDA, and Factorization Machine while it depends.

Multi-class Classfication

• Perceptron

• Passive Aggressive (PA, PA1, PA2)

• Confidence Weighted (CW)

• Adaptive Regularization of Weight Vectors (AROW)

• Soft Confidence Weighted (SCW1, SCW2)

• Random Forest Classifier

• Gradient Tree Boosting (Experimental)

My recommendation is AROW and SCW while it depends.

Regression

• Logistic Regression using Stochastic Gradient Descent

• AdaGrad, AdaDelta (w/ logistic Loss)

• Passive Aggressive Regression (PA1, PA2)

• AROW regression

• Random Forest Regressor

• Factorization Machine (w/ squared loss)

• Polynomial Regression

My recommendation for is AROW regression, AdaDelta, and Factorization Machine while it depends.

Recommendation

• Minhash (LSH with jaccard index)

• Matrix Factorization (sgd, adagrad)

• Factorization Machine (squared loss for rating prediction)

k-Nearest Neighbor

• Minhash (LSH with jaccard index)

• b-Bit minhash

• Brute-force search using Cosine similarity

Anomaly Detection

• Local Outlier Factor (LOF)

Natural Language Processing

• English/Japanese Text Tokenzier

Feature engineering

• Feature Hashing (MurmurHash, SHA1)

• Feature scaling (Min-Max Normalization, Z-Score)

• Polynomial Features

• Feature instances amplifier that reduces iterations on training

• TF-IDF vectorizer

• Bias clause

• Data generator for one-vs-the-rest classifiers

System requirements

• Hive 0.11 or later

• Java 7 or later

  Note: It would work for Java 6 except hivemall-nlp but we recommend to use Java 7 or later.
