What is TF-IDF

TF-IDF stands for "Term Frequency, Inverse Document Frequency." It's a way to score the importance of words (or "terms") in a document based on how frequently they appear across multiple documents. ​ Intuitively…If a word appears frequently in a document, it's important. Give the word a high score.But if a word appears in many documents, … Continue reading What is TF-IDF

Neural Networks using Keras (with Image recognition case study)

Problem Statement: Here, we need to identify the digit in given images. We have total 70,000 images, out of which 49,000 are part of train images with the label of digit and rest 21,000 images are unlabeled (known as test images). Now, We need to identify the digit for test images. However there are lots … Continue reading Neural Networks using Keras (with Image recognition case study)
