# Machine Learning Functions {#machine-learning-functions}
## evalMLMethod {#machine_learning_methods-evalmlmethod}
Prediction using fitted regression models uses `evalMLMethod` function. See link in `linearRegression`.
## stochasticLinearRegression {#stochastic-linear-regression}
The [stochasticLinearRegression](../../sql-reference/aggregate-functions/reference/stochasticlinearregression.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.
## stochasticLogisticRegression {#stochastic-logistic-regression}
The [stochasticLogisticRegression](../../sql-reference/aggregate-functions/reference/stochasticlogisticregression.md#agg_functions-stochasticlogisticregression) aggregate function implements stochastic gradient descent method for binary classification problem. Uses `evalMLMethod` to predict on new data.
