WebK-means clustering on text features¶. Two feature extraction methods are used in this example: TfidfVectorizer uses an in-memory vocabulary (a Python dict) to map the most frequent words to features indices and hence compute a word occurrence frequency (sparse) matrix. The word frequencies are then reweighted using the Inverse Document … Web2 feb. 2024 · Lorsque vous mettez m exemples dans un minibatch, il vous faut faire 0(m) calculs et utiliser 0(m) mémoire, mais vous réduisez le total d’incertitude dans le gradient par un facteur de seulement 0(sqrt(m)). En d’autres mots, il y a des retours qui diminuent marginalement lorsqu’on met plus d’exemples dans le minibatch.
