The proportion of data to be sampled from the full dataset. Use a value between 0 and 1 for a proportion (e.g. 0.5 for 50%), or for a specific number of examples, use an integer larger than 1. Leave blank for no sampling
Drop document if the total words is lower than this value
>= 1

Default: 1
Drop document if the total words is greater than this value
>= 1
exclusiveMinimum: false

Whether to lower case all words in training, i.e. whether to treat upper case and lower case words equally. Only utilized for custom embeddings or for the default model base: word_en_300d_2M.
Default: false
Maximum number of words in vocabulary, words will be trimmed if frequency is too low. Only utilized for custom embeddings or for the default model base: word_en_300d_2M.
>= 1
exclusiveMinimum: false
Number of epochs to train custom word2vec embeddings
Default: 15
Solr collection or cloud storage path which contains extra documents that will be used to get better vocabulary coverage as well as to train custom word embeddings if custom Model Base is specified.
Which fields in the text collection to use. If multiple fields, please separate them by comma, e.g. description_t,title_t.
The format of the texts training data - solr, parquet etc.
Word-vector dimensionality to represent text (suggested dimension ranges: 100~300)
Default: 150
The window size (context words from [-window, window]) for Word2Vec
Default: 8
Proportion of the unique questions that should be used as validation samples. When val_size > 1, then that specific number of unique questions will be sampled rather than a proportion.
>= 0.001
exclusiveMinimum: false
Default: 0.1
Maximum length of text processed by the model. Texts longer than this value will be trimmed. This parameter is especially important for Transformer-based models as it affects training and inference time. Note that the maximum supported length for Transformer models is 512, so you can specify any value up to that. The default value is the max value between three times the STD of question lengths and two times the STD of answer lengths.
Fraction of input to drop with Dropout layer (from 0-1)
Default: 0.3
Batch size during training. If left blank, this will be set automatically based on the input data
Batch size during validation. If left blank, this will be set automatically based on the input data
List of layers of RNNs to be used, with possible values of lstm, gru. E.g. ["lstm", "lstm"]. This value will be automatically decided based on data if left blank
List of RNN layer units numbers, corresponding to RNN function list. E.g. 150, 150. This value will be automatically decided based on data if left blank
L2 penalty used in AdamW optimizer. Bigger values will provide stronger regularization. Default values are 0.0003 for RNN models and 0.01 for Transformer models.
Stop training if no improvement in metrics by this number of epochs
Base learning rate that should be used during training. Reasonable values are from 0.0001 to 0.003 depending on model base. It's better to use lower LR with Transformer models.
Minimum learning rate used during training. Reasonable values are from 0.00001 to 0.00003.
Number of epochs used for the warm-up stage for learning rates. Reasonable values are from 0-4 epochs, usually 1-2 are used.
Number of epochs used in flat stage for learning rates. Reasonable value would be one-half of the epochs, so the other half will be with Cosine Annealing learning rate.
The main metric at k that should be monitored to decide when to stop training. Possible metrics are: ["map", "mrr", "recall", "precision"]
Default: mrr@3
List of evaluation metrics on validation data that will be printed in the log at the end of each epoch. Possible metrics are: ["map", "mrr", "recall", "precision"]

Default: false
Epsilon is the AdamW optimizer. By default 1e-8 is used for RNN models and 1e-6 is used for Transformer models.
Max norm used for gradients clipping. By default it’s not used for RNN models but 1.0 value is used for Transformer models.
Stores encoded representations of previous batches in memory for better negative examples sampling. Works well for Transformer models. Leave this at 'auto' to let the training module determine this.
