I try to use tft.compute_and_apply_vocabulary and tft.tfidf to compute tfidf in my jupyter notebook. However I always get the following error: tensorflow.python.framework.errors_impl.InvalidArgumentError: You must feed a valueforplaceholder tensor'compute_and_apply_vocabulary/vocabu...
For most NLP tasks the second step is to calculate the term frequency–inverse document frequency (TF-IDF). Here's the approach: tfidf(t,d,D) = tf(t,d) * idf(t,D) IDF(t) = log_e(total number of documents / number of documents that contain term t) Where t denotes the terms;...
Can someone please tell me what support I can get from Lucene to compute this ? What parameters I can directly calculate from Lucene (can I get tf, idf directly through some method in lucene?) and how to compute cosine similarity with Lucene (is there any function which directly ...

The simple way to calculate days between two dates is to remove both of their time component i.e. setting hours, minutes, seconds and milliseconds to 0 and then subtracting their time and diving it with milliseconds worth of one day. var firstDate= new Date(firstDate.setHours(0,0,0,0...
