Advanced Machine Learning made easy, efficient, reproducible
There are some options you can define in your .Rprofile (usually found in your home directory), so you do not have to define each time you execute a function.
General plotting theme; set to e.g. "whiteigrid" or "darkgraygrid"
Name of default palette to use in plots. See options by running rtpalette()
Font family to use in plots.
Number of cores to use. By default, rtemis will use available cores reported by future::availableCores(). In shared systems, you should limit this as appropriate.
Default plan to use for parallel processing.
Static graphics are handled using the mplot3 family.
Dynamic graphics are handled using the dplot3 family.
Functions for Regression and Classification begin with s_*.
Run select_learn to get a list of available algorithms
The documentation of each supervised learning function indicates in
brackets, after the title whether the function supports classification,
regression, and survival analysis [C, R, S]
Functions for Clustering begin with c_*.
Run select_clust to get a list of available algorithms
Functions for Decomposition and Dimensionality reduction begin with
d_*.
Run select_decom to get a list of available algorithms
Functions for Cross-Decomposition begin with x_*.
Run xselect_decom to get a list of available algorithms
Meta models are trained using meta* functions.
Function documentation includes input type (e.g. "String", "Integer", "Float"/"Numeric", etc) and range in interval notation where applicable. For example, Float: [0, 1)" means floats between 0 and 1 including 0, but excluding 1
For all classification models, the outcome should be provided as a factor, with the first level of the factor being the 'positive' class, if applicable. A character vector supplied as outcome will be converted to factors, where by default the levels are set alphabetically and therefore the positive class may not be set correctly.

Important Note: We assume that true labels are a factor where the first level is the "positive" case, a.k.a. the event. All methods used here, "pROC", "auc_pairs", "ROCR", have been setup to expect this. This goes against the default setting for both "pROC" and "ROCR", which will not give an AUC less than .5 because they will reorder levels. We don't want this because you can have a classifier perform worse than .5 and it can be very confusing if levels are reordered automatically and different functions give you different AUC.

Numeric vector, length = ncol(x): Use in kernel density estimation for steepest ascent classification. |
alpha |
Numeric: A scalar tuning parameter for normal kernels. When this parameter is set to zero, the mean shift algorithm will operate as usual. When this parameter is set to one, the mean shift algorithm will be approximated through Newton's Method. When set to a value between zero and one, a generalization of Newton's Method and mean shift will be used instead providing a means to balance convergence speed with stability. |
iterations |
Integer: Number of iterations to perform |
epsilon |
Numeric: used to determine when to terminate the iteration of an individual query point. If the distance between the query point at iteration i and i+1 is less than epsilon, then iteration ceases on this point. |
epsilonCluster |
Numeric: Used to determine the minimum distance between distinct clusters. This distance is applied after all iterations have finished and in order of the rows of queryData. |
parameters |
A scalar or vector of paramters used by the specific algorithm. There are no optional parameters for the "LINEAR" method, "KDTREE" supports optional parameters for the maximum number of points to store in a leaf node and the maximum value for the quadratic form in the normal kernel, ignoring the constant value -0.5. |

This is a work in progress to be potentially incorporated into train_cv
You start by training a cross-validated model using train_cv, then this function
can be used to calibrate the model. In order to use all available data, each outer
resample from the input mod is resampled (using 5-fold CV by default) to train
and test calibration models. This allows using the original label-based metrics
of mod and also extract calibration metrics based on the same data, after
aggregating the test set predictions of the calibration models.

Invert a color or calculate the mean of two colors in HSV or RGB space. This may be useful in creating colors for plots
colorOp(col, fn = c("invert", "mean"), space = c("HSV", "RGB"))colorOp(col, fn = c("invert", "mean"), space = c("HSV", "RGB"))
col |
Input color(s) |
fn |
Character: "invert", "mean": Function to perform |
space |

For multiple box plots, the recommendation is:
x=dat[, columnindex] for multiple variables of a data.frame
x=list(a=..., b=..., etc.) for multiple variables of potentially
different length
x=split(var, group) for one variable with multiple groups: group names
appear below boxplots
x=dat[, columnindex], group = factor for grouping multiple variables:
group names appear in legend
If orientation == "h", xlab is applied to y-axis and vice versa.
Similarly, x.axist.type applies to y-axis - this defaults to
"category" and would not normally need changing.

Checks if grid search needs to be performed.
All tunable parameters should be passed to this function, individually or as
a list. If any argument has more than one assigned values, the function
returns TRUE, otherwise FALSE. This can be used to check whether
gridSearchLearn must be run.

The idea is that if you know which parameter values you want to use, you
define them directly
e.g. alpha = 0, lambda = .2.
If you don't know, you enter the set of values to be tested,
e.g. alpha = c(0, .5, 1), lambda = seq(.1, 1, .1).

The main difference from the original stats::heatmap is the addition of a colorbar on the side.
This is achieved with colorGrad.
Other differences:
Dendrograms are not drawn by default. Set Rowv = T and Colv = T to get them.
Column labels are only drawn perpendicular to the x-axis if any one is
longer than two characters.
Otherwise, the arguments are the same as in stats::heatmap

You can group data either by supplying x as a list where each element contains one vector per
group, or as a data frame where each column represents group,
or by providing a group variable, which will be converted to factor.
For bivariate plots, see mplot3_xy and mplot3_xym. For heatmaps, see
mplot3_heatmap
To plot histograms of multiple groups, it's best to use hist.type = "lines", which will
use mhist
and space apart the breaks for each group
Invisibly returns the output of density, hist, qqnorm, or NULL

For calibration plots, type = "aggregate.all" is likely the more informative one.
It shows calibrations curves before and after calibration by aggregating across all
outer test sets. The type = "aggregate.by.resample" option shows the calibration
curves after calibration for each outer resample.
For Brier boxplots, type = "aggregate.all" shows 1 score per outer resample prior
to calibration and multiple (equal n.resamples used in calibrate_cv) brier scores
per outer resample after calibration. This is for diagnostic purposes mainly.
For presentation, the type = "aggregate.by.resample" option shows the mean Brier
score per outer resample prior to calibration and after calibration and makes more
sense. The uncalibrated estimates could be resampled using the calibration model
resamples to produce a more comparable boxplot of Brier scores when using the
type = "aggregate.all" option, but that seems artifactual.
More options are certainly possibly, e.g. an "aggregate.none" that would show all calibration resamples for all outer ersamples, and can be added in the future if needed.

Create resamples of your data, e.g. for model building or validation.
"bootstrap" gives the standard bootstrap, i.e. random sampling with replacement, using
bootstrap, "strat.sub" creates stratified subsamples using strat.sub,
while "strat.boot" uses strat.boot which runs strat.sub and then
randomly duplicates some of the training cases to reach original length of input
(default) or length defined by target.length.

resample is used by multiple rtemis learners, gridSearchLearn, and
train_cv. Note that option 'kfold', which uses kfold results in resamples
of slightly different length for y of small length, so avoid all operations which rely
on equal-length vectors. For example, you can't place resamples in a data.frame, but
must use a list instead.

This function is for binary classification. The outcome must be a factor with two levels, the first level is the 'positive' class. Ensure there are no missing values in the data and that variables are either numeric (including integers) or factors. Use preprocess as needed to impute and convert characters to factors.
Factor levels should not contain the "/" character (it is used to separate conditions in the addtree object)
[gS] Indicates that more than one value can be supplied, which will result in grid search using internal resampling lambda = gamma/(1 - gamma)

Early stopping is implemented by fitting n.trees initially, checking the
optionally smoothed validation error curve, and adding n.new.trees if
needed, until error does not reduce or max.trees is reached.
[gS] in the argument description indicates that a vector of values can be
passed, in which case grid search will be performed automatically using the
resampling scheme defined by grid.resample.params.
This function includes a workaround for when gbm.fit fails.
If an error is detected, gbm.fit is rerun until successful and the
procedure continues normally

A common problem with glm arises when the testing set containts a predictor with more
levels than those in the same predictor in the training set, resulting in error. This can happen
when training on resamples of a data set, especially after stratifying against a different
outcome, and results in error and no prediction. s_GLM automatically finds such cases
and substitutes levels present in x.test and not in x with NA.

GLS can be useful in place of a standard linear model, when there is correlation among
the residuals and/or they have unequal variances.
Warning: nlme's implementation is buggy, and predict will not work
because of environment problems, which means it fails to get predicted values if
x.test is provided.
robut = TRUE trains a robust linear model using MASS::rlm.
gls = TRUE trains a generalized least squares model using nlme::gls.

You should cconsider, or try, setting mtry to NCOL(x), especially for small number of features.
By default mtry is set to NCOL(x) for NCOL(x) <= 20.
For imbalanced datasets, setting stratify.on.y = TRUE should improve performance.
If autotune = TRUE, randomForest::tuneRF will be run to determine best mtry
value.
[gS]: indicated parameter will be tuned by grid search if more than one value is passed

Logical: If TRUE, sets |
... |
Additional train.params to be passed to learner. Will be concatenated
with |
Note on resampling: You should never use an outer resampling method with replacement if you will also be using an inner resampling (for tuning). The duplicated cases from the outer resampling may appear both in the training and testing sets of the inner resamples, leading to underestimated testing error.
If there is an error while running either the outer or inner resamples in parallel, the error message returned by R will likely be unhelpful. Repeat the command after setting both inner and outer resample run to use a single core, which should provide an informative message.
The train command is replacing elevate.
Note: specifying id.strat for the inner resampling is not yet supported.

Given an index of columns, convert identified columns of data.frame to factor, ordered factor, or integer. A number of datasets are distributed with an accompanying index of this sort, especially to define which variables should be treated as categorical (here, factors) for predicting modeling. This functions aims to make data type conversions in those cases easier.

Matrix: Training z dataset |
x.test |
Matrix (Optional): Testing x set |
z.test |
Matrix (Optional): Testing z set |
y |
Outcome vector (Optional): If supplied, linear combinations of |
outcome |
Character: Type of outcome |
k |

typex |
Character: "standard", "ordered". Use "standard" if columns of x are unordered; lasso penalty is applied to enforce sparsity. Otherwise, use "ordered"; fused lasso penalty is applied, to enforce both sparsity and smoothness. |
typez |
Character: "standard", "ordered". Same as |
penaltyx |
Float: The penalty to be applied to the matrix x, i.e. the penalty that results in the canonical vector u. If typex is "standard" then the L1 bound on u is penaltyx*sqrt(ncol(x)). In this case penaltyx must be between 0 and 1 (larger L1 bound corresponds to less penalization). If "ordered" then it's the fused lasso penalty lambda, which must be non-negative (larger lambda corresponds to more penalization). |
penaltyz |
Float: The penalty to be applied to the matrix z, i.e. the penalty that results in the canonical vector v. If typez is "standard" then the L1 bound on v is penaltyz*sqrt(ncol(z)). In this case penaltyz must be between 0 and 1 (larger L1 bound corresponds to less penalization). If "ordered" then it's the fused lasso penalty lambda, which must be non-negative (larger lambda corresponds to more penalization). |
standardize |
Logical: If TRUE, center and scale columns of |
upos |
Logical: Require elements of u to be positive |
vpos |
Logical: Require elements of v to be positive |
verbose |
Logical: Print messages, including |
n.cores |
Integer: Number of cores to use |
outdir |
Path to output directory. Default = NULL |
