What’s New in SuperML Java 3.0.1

SuperML Java 3.0.1 represents a major milestone in the framework’s evolution, introducing state-of-the-art Transformer architectures and comprehensive PMML export capabilities. This release elevates SuperML from a classical ML library to a complete, modern ML platform.

🎉 Major New Features

1. Complete Transformer Architecture Implementation

SuperML 3.0.1 introduces a fully production-ready Transformer implementation following the “Attention Is All You Need” paper:

🤖 Three Architecture Variants

✅ Core Components (100% Complete)

MultiHeadAttention: Scaled dot-product attention with configurable heads
PositionalEncoding: Sinusoidal position embeddings
LayerNorm: Feature-wise normalization with learnable parameters
FeedForward: Two-layer MLP with ReLU/GELU activation
TransformerBlock: Complete encoder/decoder blocks

Quick Example:

// BERT-style text classification
TransformerEncoder classifier = new TransformerEncoder.Builder()
    .modelDimension(512)
    .numLayers(6)
    .numHeads(8)
    .numClasses(2)
    .build();

classifier.fit(tokenizedTexts, labels);
double[] predictions = classifier.predict(testTexts);

2. Production-Ready PMML Export

Complete PMML 4.4 support for cross-platform model deployment:

🔄 Supported Models

✅ LinearRegression - Coefficients and intercept export
✅ LogisticRegression - Logit normalization and class probabilities
✅ Ridge/Lasso - Regularization metadata and coefficients
✅ DecisionTree - Hierarchical tree structure and splits
✅ RandomForest - Ensemble representation with majority voting

🌐 Cross-Platform Deployment

Apache Spark MLlib - Direct pipeline integration
Python scikit-learn - jpmml-evaluator support
R Environment - Native PMML package compatibility
Enterprise Systems - SAS, SPSS, Azure ML, Amazon SageMaker

Quick Example:

// Export model with business-friendly names
PMMLConverter converter = new PMMLConverter();
String[] features = {"customer_age", "annual_income", "credit_score"};
String pmmlXml = converter.convertToXML(model, features, "loan_approval");

boolean isValid = converter.validatePMML(pmmlXml);
Files.write(Paths.get("business_model.pmml"), pmmlXml.getBytes());

Transformer Quick Start

import org.superml.transformers.models.TransformerEncoder;
import org.superml.transformers.tokenization.AdvancedTokenizer;

// Create and use a transformer for text classification
AdvancedTokenizer tokenizer = new AdvancedTokenizer.Builder()
    .vocabSize(30000)
    .maxLength(512)
    .build();

TransformerEncoder model = new TransformerEncoder.Builder()
    .modelDimension(512)
    .numLayers(6)
    .numHeads(8)
    .numClasses(2)
    .dropout(0.1f)
    .build();

// Train
String[] texts = {"I love this!", "This is terrible"};
int[] labels = {1, 0};
int[][] tokenizedTexts = tokenizer.batchTokenize(texts);
model.fit(tokenizedTexts, labels);

// Predict
double[] predictions = model.predict(tokenizer.batchTokenize(new String[]{"Great!"}));

PMML Export Quick Start

import org.superml.pmml.PMMLConverter;
import org.superml.linear_model.LogisticRegression;

// Train any SuperML model
LogisticRegression model = new LogisticRegression();
model.fit(X_train, y_train);

// Export to PMML for cross-platform deployment
PMMLConverter converter = new PMMLConverter();
String pmmlXml = converter.convertToXML(model);

// Validate and save
if (converter.validatePMML(pmmlXml)) {
    Files.write(Paths.get("model.pmml"), pmmlXml.getBytes());
    System.out.println("✅ Model ready for deployment!");
}
