General

Throughout all methods, we will use 5-fold cross validation, as our resampling method, by specifying "repeatedcv" as the method argument to a caret::trainControl(). Similar to before, we will use Rsquared as our performance metric.

From here on out, we will use basis_form to refer to our previously defined basis formula.

my_ctrl <- caret::trainControl(method = "repeatedcv", number = 5, repeats = 5)
rsquared_metric <- "Rsquared"
basis_form <- as.formula(paste("response_1 ~ xA + xB*(splines::ns(x01, df = 2) + splines::ns(x02, df = 2) + splines::ns(x03, df = 2))"))

Linear additive model

First we will train a linear additive model on our previously defined basis function using caret::train and setting method="lm".

The main purpose of this linear additive model is to provide a baseline comparison to the other complex models we will train.

set.seed(12345)
mod_lin_add <- caret::train(form = basis_form,
                            method = "lm", 
                            metric = rsquared_metric, 
                            trControl = my_ctrl,
                            data = step_1_df)

Regularized regression with elastic net

We will train two different models with interactions, specifically one with all pair interactions between all step 1 input variables, and one with all triplet interactions. Given \(n\) coefficients, the number of coefficients that must be learned for a model with all \(m\)-input interactions will be modeled by:

\[ \sum_{k=1}^{m} \left( \begin{array} {c} n \\ k \end{array} \right) \]

However, for each categorical input variable, we have to subtract the number of possibilites of interactions between categories within a single variable.

So, for all pair interactions between all step 1 continuous input variables, the number of coefficients that must be learned is \(10 + \left(\begin{array}{c} 10 \\ 2 \end{array}\right) - \left(\begin{array}{c} 3 \\ 2 \end{array}\right) = 52\), excluding intercept. For all triplet interactions, the number of coefficients that must be learned is \(52 + \left(\begin{array}{c} 10 \\ 3 \end{array}\right) - 3\left(\begin{array}{c} 10 - 3 \\ 1 \end{array}\right) - \left(\begin{array}{c} 3 \\ 3 \end{array}\right) = 150\), excluding intercept.

All pair interactions between step 1 inputs

Let’s first fit a regularized regression model with elastic net, on all pairwise interactions between all step 1 inputs, using caret::train with method="glmnet". We specify centering and scaling as preprocessing steps.

set.seed(12345)
mod_glmnet_2 <- caret::train(response_1 ~ (.)^2,
                             method = "glmnet",
                             preProcess = c("center", "scale"),
                             metric = rsquared_metric,
                             trControl = my_ctrl,
                             data = step_1_df)

ggplot(mod_glmnet_2)

Create a custom tuning grid enet_grid to try out many possible values of the penalty factor (lambda) and the mixing fraction (alpha).

                         lambda = exp(seq(-6, 0.5, length.out = 25)))

Now retrain the pairwise interactions model using tuneGrid = enet_grid, then extracting the optimal tuning parameters.

Optimal tuning parameters found by caret’s method="nnet" are 5 hidden units (single layer), 0.1 decay.

Now using a more refined search grid over the tuning parameters.

nnet_grid <- expand.grid(size = c(2, 4, 6, 8, 10),
                         decay = c(1e-4, 0.1, 0.5))

Fitting the nnet model using this more refined search grid. The grid search might take a few minutes.

Random forest

Random forests have become a handy and convenient learning algorithm that has good predictive performance with “relatively little hyperparameter tuning”. We will use method = "rf" that allows us to use caret::train as we have for all other models. Importantly, we set importance = TRUE (no pun intended). The code chunk below might take a few minutes to run to completion.

set.seed(12345)
mod_rf_step1 <- caret::train(response_1 ~ .,
                             method = "rf",
                             importance = TRUE,
                             trControl = my_ctrl,
                             metric = rsquared_metric,
                             data = step_1_df)

mod_rf_step1

## Random Forest

## Resampling: Cross-Validated (5 fold, repeated 5 times) 
## Summary of sample sizes: 1611, 1609, 1611, 1610, 1611, 1610, ... 
## Resampling results across tuning parameters:

##   mtry  RMSE      Rsquared   MAE     
##    2    3.059271  0.7412863  2.129406

## Rsquared was used to select the optimal model using the largest value.
## The final value used for the model was mtry = 6.

Fit the rf model to the basis function.

Gradient boosted tree

Gradient boosting machines (GBM) build shallow trees in sequence, with each tree “learning and improving on the previous one”; as opposed to random forests which build deep independent trees. When gradient boosted and tuned, these shallow trees collectively form one of the best predictive models.

Set method = "xgbTree" in caret::train.

set.seed(12345)
mod_gbm_step1 <- caret::train(response_1 ~ .,
                              method = "xgbTree",

Support Vector Regression

The motivation for fitting a Support Vector Machine (SVM) is that SVMs have several advantages compared to other methods, as mentioned in the Hands-On Machine Learning with R book:

• SVMs attempt to maximize generalizability;
• SVMs are always guaranteed to find a global optimum since they are convex optimization problems, and don’t get stuck in local optima unlike in neural networks;
• SVMs are relatively robust to outliers by using a cost parameter;
• SVMs are flexible in adapting to complex nonlinear decision boundaries using kernel functions, e.g. the radial basis kernel

First, load kernlab library.

library(kernlab)

## Attaching package: 'kernlab'

## The following object is masked from 'package:purrr':
## 
##     cross

## The following object is masked from 'package:ggplot2':
## 
##     alpha

In Support Vector Regression (SVR), we will stick to the general rule of thumb to use a radial basis kernel in our caret::train call, using method="svmRadial".

First see what are the parameters to be learned:

caret::getModelInfo("svmRadial")$svmRadial$parameters

##   parameter   class label
## 1     sigma numeric Sigma
## 2         C numeric  Cost

Now fit the model.

set.seed(12345)
mod_svr <- caret::train(form = basis_form,
                        method = "svmRadial",
                        preProcess = c("center", "scale"),
                        tuneLength = 10,
                        metric = rsquared_metric,
                        trControl = my_ctrl,

Multivariate Adaptive Regression Splines

The motivation for fitting a Multivariate Adaptive Regression Splines (MARS) model is to explore more nonlinear relationships between the step 1 inputs, unlike the first linear three models we trained in part iiA. Although our previously defined basis function that crosses categorical inputs with natural spline functions of x01 to x03 has been by far the best model, MARS is capable of extending linear models to capture multiple nonlinear relationships by searching for and discovering nonlinearities and interactions in the data that will help maximize predictive accuracy.

First, load earth library for MARS modeling.

library(earth)

## Loading required package: Formula

## Loading required package: plotmo

## Loading required package: plotrix

## Loading required package: TeachingDemos

Hands-On Maching Learning in R describes the inner workings of MARS. Instead of explicitly defining polynomial functions or natural spline functions ourselves, MARS provides a convenient approach to capture the nonlinear relationships in the data by assessing cutpoints, like step functions. The procedure assesses each data point for each input as a knot and creates a linear regression model with the candidate feature(s).

Basic MARS model

mod_mars_basic <- earth(response_1 ~ ., 
                        data = step_1_df)

This basic model tells us that 7 out of the 10 predictors were used, leaving out xA, x04 and x05, with a resulting Rsquared of 0.5406884.

plot(mod_mars_basic)

Tuning and resampling

To help in the tuning of this procedure, we can specify tuning parameters such as the maximum degree of interactions, degree, and the number of terms retained in the final model, nprune, in a tuning grid to be passed into the caret::train call. Since there is rarely any benefit in assessing greater than triplet interactions, we choose degree = 1:3. We also start out with 10 evenly spaced values and intend to zoom in when we later find an approximate optimal solution and there is cause to.

mars_grid <- expand.grid(degree = 1:3,
                         nprune = seq(2, 100, length.out = 10) %>% floor())

mars_grid %>% head()

##   degree nprune
## 1      1      2
## 2      2      2
## 3      3      2
## 4      1     12
## 5      2     12
## 6      3     12

We will use caret::train, as in the previous sections. The grid search might take a few minutes.

set.seed(12345)
mod_mars <- caret::train(response_1 ~ .,
                         method = "earth",
                         tuneGrid = mars_grid,
                         metric = rsquared_metric,
                         trControl = my_ctrl,
                         data = step_1_df)

## Rsquared was used to select the optimal model using the largest value.
## The final values used for the model were nprune = 23 and degree = 2.

The best model identified has Rsquared value of 0.8148037, with parameters nprune = 23 and degree = 2.

Plot the model.

ggplot(mod_mars)

For both degree = 2 and degree = 3, they yield the same Rsquared values, explaining the overlap in the plot, and the “absence” of degree 2.

Here, because the optimal Rsquared values stay constant beyond roughly nprune = 23 terms, there is no need to adjust to a more specific tuning grid.

Comparing methods

Now that we have fit all of the models, we can compare the cross-validation hold-out set performance metrics. We first compile all of the “resample” results together with the resamples() function.

iiC_results <- resamples(list(lm_basis = mod_lin_add,
                              glmnet_basis = mod_glmnet_basis,
                              glmnet_2way = mod_glmnet_2_b,
                              glmnet_3way = mod_glmnet_3_b,
                              nnet_basis = mod_nnet_b,
                              nnet_step1 = mod_nnet_step1,
                              rf_basis = mod_rf_basis,
                              rf_step1 = mod_rf_step1,
                              gbm_basis = mod_gbm_basis,
                              gbm_step1 = mod_gbm_step1,
                              svr_basis = mod_svr,
                              mars_basis = mod_mars))

Then we visually compare the performance metrics.

dotplot(iiC_results)

dotplot(iiC_results, metric = "RMSE")

dotplot(iiC_results, metric = "Rsquared")

dotplot(iiC_results, metric = "MAE")

Manually extract the results to make a custom figure.

iiC_results_lf <- 
  as.data.frame(iiC_results, metric = "RMSE") %>% tibble::as_tibble() %>% 
    mutate(metric_name = "RMSE") %>% 
  bind_rows(as.data.frame(iiC_results, metric = "Rsquared") %>% tibble::as_tibble() %>% 
    mutate(metric_name = "Rsquared")) %>% 
  bind_rows(as.data.frame(iiC_results, metric = "MAE") %>% tibble::as_tibble() %>% 
    mutate(metric_name = "MAE")) %>% 
  tidyr::gather(key = "model_name", value = "metric_value", -Resample, -metric_name)

iiC_results_lf %>% 
  ggplot(mapping = aes(x = model_name, y = metric_value)) +
  geom_boxplot() +
  stat_summary(fun.data = "mean_se",
               color = "red",
               fun.args = list(mult = 1)) +
  coord_flip() +
  facet_grid(. ~ metric_name, scales = "free_x") +
  theme_bw()

Clearly, the three best models are lm, glmnet_basis, and svr_basis, in that order.

as.data.frame(iiC_results, metric = "RMSE") %>% 
  GGally::ggpairs(columns = 1:12)

## Registered S3 method overwritten by 'GGally':
##   method from

Additionally, models lm_basis and glmnet_basis are highly correlated, as are glmnet_2way-glmnet_3way, rf_basis-rf_step1, rf_step1-gbm_basis.
