Thanks Nick,

I had a problem reading back an object.  Here is my code snippet

SparseAveragedPerceptron p = new SparseAveragedPerceptron(learningRate, 
threshold, thickness);
p.initialize(dataSize, featureSize)

for (int i = 1; i <= rounds; i++) {
    for (each data instance)
        p.learn(featureIndex, featureValue, labelIndex, lablelValue);
    p.doneWithRound();
}
p.doneLearning();

p.write(new ExceptionlessOutputStream(new ObjectOutputStream(new 
FileOutputStream("file")));
p.read(new ExceptionlessInputStream(new ObjectInputStream(new 
FileInputStream("file")));

Here is the error I got:
Error in UTF formatting: malformed input around byte 14

What is the recommended way of saving and reading?
