Quantitative parameters now print the number of possible values if they have been set with value_set() (@kmdupr33, #138).
The print() method for parameters() has changed to be more clear.
A new function, pull_dials_object() was also added.
Duplicate parameter combinations are now automatically removed from grid results.
The range for epochs() was change to start at 10 iterations instead of 1.
The lower range for spline_degree() now starts at 1 instead of 3.
The upper range for cost() now goes to 2^5 instead of 2^-1.
The grid_*() functions no longer generate subclassed tibbles.
predictor_prop() was added.
The levels argument for tune_grid() can now handle a named vector, to account for differences in ordering.
The range of dist_power() was changed so that the lower limit is 1.
The deprecation period for margin() is over; please use svm_margin() instead.
When kept in the original units, a parameter’s range must now be the same data type as the parameter.
Renamed margin() to svm_margin() (@gabrielodom and @gralgomez, #85)
A bug in space filling designs with qualitative parameters was fixed (#94)
A better error message was created when grids are used with parameters sets that contain parameters that require finalization (#99)
Space-filling desings now share the same attributes as other grid objects (#100)
The range for sample_frac() was fixed (#96)
smoothness() was added.param_set() is being renamed parameters(). The old name implied that you only use it to set parameters (say from a recipe or model rather than de novo). param_set() will be available until version 0.0.5.
The range for num_hash() was increase to be 2^8 to 2^12.
The range for max_tokens() was changed to be 0 to 1000.
offset() has been renamed kernel_offset() to avoid name conflicts.All parameter objects are now parameter functions. For example, the pre-configured object mtry is now a function, mtry(), with arguments for the range and the trans. This provides greater flexibility in parameter creation, and should feel more natural.
deg_free() erroneously produced real values; integers are now returned.
Default ranges were changed for learn_rate() and neighbors() were changed.
update.param_set() now takes multiple named arguments.
Two functions for space-filling designs were added: grid_max_entropy() and grid_latin_hypercube().
A data set was added for modeling ridership on the Chicago L trains.
spline_degree(), over_ratio(), under_ratio(), freq_cut(), unique_cut(), num_breaks(), min_unique(), num_hash(), signed_hash(), sample_prop(), window_size(), min_dist(), and degree_int() were added.Parameter objects now contain code to finalize their values and a number of helper functions for certain data-specific parameters. A force option can be used to avoid updating the values.
Parameter objects are printed differently inside of tibbles.
regularization was changed to penalty in a few models to be consistent with this change.
batch_size and threshold were added.
Added a set of parameters for the textrecipes package issue 16.
