Bases: transformers.training_args.TrainingArguments

Class that inherits HF TrainingArguments and add on top of it arguments needed for session-based and sequential-based recommendation

Parameters

• shuffle_buffer_size (int) –

• validate_every (Optional[int], int) – Run validation set every this epoch. -1 means no validation is used by default -1

• eval_on_test_set (bool) –

• eval_steps_on_train_set (int) –

• predict_top_k (Option[int], int) – Truncate recommendation list to the highest top-K predicted items (do not affect evaluation metrics computation) by default 10

• log_predictions (Optional[bool], bool) – log predictions, labels and metadata features each –compute_metrics_each_n_steps (for test set). by default False

• log_attention_weights (Optional[bool], bool) – Logs the inputs and attention weights each –eval_steps (only test set)” bu default False

• learning_rate_num_cosine_cycles_by_epoch (Optional[int], int) – Number of cycles for by epoch when –lr_scheduler_type = cosine_with_warmup. The number of waves in the cosine schedule (e.g. 0.5 is to just decrease from the max value to 0, following a half-cosine). by default 1.25

• experiments_group (Optional[str], str) – Name of the Experiments Group, for organizing job runs logged on W&B by default “default”
