java.lang.Object
- ml.shifu.guagua.io.HaltBytable
- - ml.shifu.guagua.example.lr.LogisticRegressionParams

All Implemented Interfaces:

ml.shifu.guagua.io.Bytable
```
public class LogisticRegressionParams
extends ml.shifu.guagua.io.HaltBytable
```
A model class to store logistic regression weight on first iteration by using parameters, while in other iterations parameters is used to store gradients.
To make all workers started at the same model, master will compute a consistent model weights at the first iteration and then send to all the workers. Workers will start computing from the second iteration.
Workers are responsible to compute local accumulated gradients and send to master while master accumulates all gradients together to build a global model.
