This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor.

This is typically the number of times a row is repeated, but non-integer values are supported as well.

Giving some observation a weight of zero is equivalent to excluding it from the dataset; giving an observation a relative weight of 2 is equivalent to repeating that row twice. Negative weights are not allowed. Note: Weights are per-row observation weights and do not increase the size of the data frame. This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor. If you set weight = 0 for a row, the returned prediction frame at that row is zero and this is incorrect. To get an accurate prediction, remove all rows with weight == 0. | In/Out |

This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor.

Giving some observation a weight of zero is equivalent to excluding it from the dataset; giving an observation a relative weight of 2 is equivalent to repeating that row twice. Negative weights are not allowed. Note: Weights are per-row observation weights and do not increase the size of the data frame. This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor. If you set weight = 0 for a row, the returned prediction frame at that row is zero and this is incorrect. To get an accurate prediction, remove all rows with weight == 0. | In/Out |

This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor. If you set weight = 0 for a row, the returned prediction frame at that row is zero and this is incorrect. To get an accurate prediction, remove all rows with weight == 0. | In/Out |

TargetEncoderParametersV3
columns_to_encode
string[][] | List of categorical columns or groups of categorical columns to encode. When groups of columns are specified, each group is encoded as a single column (interactions are created internally). | In |
keep_original_categorical_columns
boolean | If true, the original non-encoded categorical features will remain in the result frame. | In |
blending
boolean | If true, enables blending of posterior probabilities (computed for a given categorical value) with prior probabilities (computed on the entire set). This allows to mitigate the effect of categorical values with small cardinality. The blending effect can be tuned using the inflection_point and smoothing parameters. | In |
inflection_point
double | Inflection point of the sigmoid used to blend probabilities (see blending parameter). For a given categorical value, if it appears less that inflection_point in a data sample, then the influence of the posterior probability will be smaller than the prior. | In |
smoothing
double | Smoothing factor corresponds to the inverse of the slope at the inflection point on the sigmoid used to blend probabilities (see blending parameter). If smoothing tends towards 0, then the sigmoid used for blending turns into a Heaviside step function. | In |
data_leakage_handling
enum | Data leakage handling strategy used to generate the encoding. Supported options are:
1) “none” (default) - no holdout, using the entire training frame.
2) “leave_one_out” - current row’s response value is subtracted from the per-level frequencies pre-calculated on the entire training frame.
3) “k_fold” - encodings for a fold are generated based on out-of-fold data. | In |
noise
double | The amount of noise to add to the encoded column. Use 0 to disable noise, and -1 (=AUTO) to let the algorithm determine a reasonable amount of noise. | In |
seed
long | Seed used to generate the noise. By default, the seed is chosen randomly. | In |
distribution
enum | Distribution function | In |

Giving some observation a weight of zero is equivalent to excluding it from the dataset; giving an observation a relative weight of 2 is equivalent to repeating that row twice. Negative weights are not allowed. Note: Weights are per-row observation weights and do not increase the size of the data frame. This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor. If you set weight = 0 for a row, the returned prediction frame at that row is zero and this is incorrect. To get an accurate prediction, remove all rows with weight == 0. | In/Out |
offset_column
VecSpecifier | Offset column. This will be added to the combination of columns before applying the link function. | In/Out |
fold_column
VecSpecifier | Column with cross-validation fold index assignment per observation. | In/Out |

Negative weights are not allowed. Note: Weights are per-row observation weights and do not increase the size of the data frame. This is typically the number of times a row is repeated, but non-integer values are supported as well. During training, rows with higher weights matter more, due to the larger loss function pre-factor. If you set weight = 0 for a row, the returned prediction frame at that row is zero and this is incorrect. To get an accurate prediction, remove all rows with weight == 0. | In/Out |
