Launching the CI/CD and R Collectives and community editing features for How can I safely create a directory (possibly including intermediate directories)? You feed the model with a list of sentences, and it scores each whereas the lowest the better. ; Transformer: A GPT is a decoder-only transformer neural . You can simulate that by adding multiple [MASK] tokens, but then you have a problem with how to compare the scores of prediction so different lengths reliably. From what I understand, though, this is probably not a good idea, since it is unlike training, as mentioned by @thomwolf in another thread (#473 (comment)) (emphasis mine): Unfortunately, given the way the model is trained (without using a token indicating the beginning of a sentence), I would say it does not make sense to try to get a score for a sentence with only one word. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? I've tried this approach with GPT2 model using Huggingface Transformers library, but, I couldn't get satisfactory results due to the model's unidirectional nature which for me didn't seem to predict within context. as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and In this article I will describe an abstractive text summarization approach, first mentioned in $[1]$, to train a text summarizer. model_prefix: model_type: UNIGRAM vocab_size: 20 self_test_sample_size: 0 character_coverage: 0.9995 input_sentence_size: 0 shuffle_input_sentence: 1 seed_sentencepiece_size: 1000000 shrinking_factor: 0.75 max_sentence_length: 4192 num .
