When you want machine learning to convey the meaning of a text, it can do one of two things: rephrase the information, or just show you the most important parts of the content. Without adding any new parameters, we'll obtain a very powerful abstractive text summarizer after training for just 5 epochs on 3000 examples from the training dataset. ( For anyone who's interested in batching the above process, here's the code: A caveat was that token_type_ids from tokenizer.batch_encode_plus should not be passed to the gpt2_model in order to obtain the same results as the line-by-line inference. If it cannot be used as language model, I don't see how you can generate a sentence using BERT. This "answer" does not give you the probability P(word | context) but rather it predicts the most likely word. having all inputs as a list, tuple or dict in the first positional argument. elements depending on the configuration (GPT2Config) and inputs. etc.). training: typing.Optional[bool] = False logits (torch.FloatTensor of shape (batch_size, sequence_length, config.vocab_size)) Prediction scores of the language modeling head (scores for each vocabulary token before SoftMax). ) token_type_ids: typing.Optional[torch.LongTensor] = None Contains pre-computed hidden-states (key and values in the attention blocks) that can be used (see ) Developed by OpenAI, GPT-2 is a large-scale transformer-based language model. output_hidden_states: typing.Optional[bool] = None Abstractive summarization techniques commonly face issues with generating factually incorrect summaries, or summaries which are syntactically correct but do not make any sense. past_key_values: typing.Union[typing.Tuple[typing.Tuple[typing.Union[numpy.ndarray, tensorflow.python.framework.ops.Tensor]]], NoneType] = None You get two sentences such as: - I put an elephant in the fridge. bos_token_id = 50256 How to extract the coefficients from a long exponential expression?

How can I install packages using pip according to the requirements.txt file from a local directory? I see. attentions: typing.Optional[typing.Tuple[tensorflow.python.framework.ops.Tensor]] = None The documentation example wasn't very good in my opinion because instead of predicting the single, most likely word, the example fetched all possible words (50,257 of them) did some complicated filtering using the HF top_k_top_p_flitering() function, then fed those filtered results to the PyTorch multinomial() probability distribution . output_attentions: typing.Optional[bool] = None 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. Hope this question is simple to answer: How can I run the probability calculation entirely on gpu? Because of bi-directionality of BERT, BERT cannot be used as a language model. is there a chinese version of ex.

It seems like the OP concluded that you can score the whole sentence including the first word, by appending a bos_token (<|endoftext|>) at the beginning of the string. it's computing P(there|<|endoftext|>) * P(is|there,<|endoftext|>) * * P(desk|the,))? training: typing.Optional[bool] = False Path of transformer model - will load your own model from local disk. **kwargs loss: typing.Optional[torch.FloatTensor] = None encoder_attention_mask: typing.Union[numpy.ndarray, tensorflow.python.framework.ops.Tensor, NoneType] = None n_labels - How many labels are we using in this dataset. **kwargs input_ids. You can get around that behavior by passing add_prefix_space=True when instantiating this tokenizer, but since Based on byte-level Byte-Pair-Encoding. When used with is_split_into_words=True, this tokenizer needs to be instantiated with add_prefix_space=True. We fill this gap by pre-training a sentence state with complex-valued BERT-like architecture, and adapting it to the classical-quantum transfer learning scheme for sentence classification. input_ids: typing.Optional[torch.LongTensor] = None Only relevant if config.is_decoder = True. a= tensor(32.5258) So, the right way to get a sentence's probability would be. input) to speed up sequential decoding. position_ids: typing.Optional[torch.LongTensor] = None How to choose voltage value of capacitors. mc_loss: typing.Optional[torch.FloatTensor] = None Much like the autofill features on your iPhone/Android, GPT-2 is capable of next word prediction on a much larger and more sophisticated scale.

Although the recipe for forward pass needs to be defined within this function, one should call the Module Random sampling may also affect the generation of longer text as sampling interrupts the coherence across consecutive sentences. token_type_ids: typing.Optional[torch.LongTensor] = None So I should be using self.tokenizer.bos_token and self.tokenizer.eos_token to start and end a sentence properly (instead of the hardcoded 50526 |endoftext| token). padding tokens when inputs_embeds are passed instead of input_ids, it does the same (take the last value in It can be fine-tuned to solve a diverse amount of natural language processing (NLP) problems such as text generation, summarization, question answering, translation, and sentiment analysis, among others. New delimiter or special tokens can be added to the GPT tokenizer using its add_special_tokens method: Like Seq2Seq models, I also considered cross-entropy loss over target (summary) sequences because considering cross-entropy loss over both source (article) and target sequences did not change the performance. @jhlau your code does not seem to be correct to me.
