# Machine learning functions
## evalMLMethod (prediction) {#machine_learning_methods-evalmlmethod}
Prediction using fitted regression models uses `evalMLMethod` function. See link in `linearRegression`.
### Stochastic Linear Regression
The [stochasticLinearRegression](../agg_functions/reference.md#agg_functions-stochasticlinearregression) aggregate function implements stochastic gradient descent method using linear model and MSE loss function. Uses `evalMLMethod` to predict on new data.
### Stochastic Logistic Regression
The [stochasticLogisticRegression](../agg_functions/reference.md#agg_functions-stochasticlogisticregression) aggregate function implements stochastic gradient descent method for binary classification problem. Uses `evalMLMethod` to predict on new data.
