WebJun 8, 2024 · A Vocabulary object maps each word in the problem context to a 0-based integer index, based on how common the word is. For example, if you had some more or less normal source text, the word “the” might be mapped to 4 if it was the fifth most common word/token in your source text. WebCLIP. CLIP (Contrastive Language-Image Pre-Training) is a neural network trained on a variety of (image, text) pairs. It can be instructed in natural language to predict the most relevant text snippet, given an image, without directly optimizing for the task, similarly to the zero-shot capabilities of GPT-2 and 3. WebDec 23, 2024 · One way to do that is with a Counter ( Counter docs ): counter = Counter () for text in data_iter: counter.update (tokenizer (text)) You can get the frequency of the tokens from the counter, then build the vocabulary from the counter: vocab = vocab.vocab (counter, min_freq=MIN_WORD_FREQUENCY) Share Improve this answer Follow sklearn projects github
