Hugging Face DistilBert & Tensorflow for Custom Text Classification.
How to fine-tune DistilBERT for text binary classification via Hugging Face API for TensorFlow. Intro. In this tutorial, you will see a binary text classification implementation with the Transfer Learning technique. For this purpose, we will use the DistilBert, a pre-trained model from the Hugging Face Transformers library and its API for Tensorflow. Why DistilBert.…
NLP: Text Pre-processing and Feature Engineering. Python.
Pre-process text data, create new features (including target variable for binary classification) with Python: Numpy, Pandas, Regex, Spacy, and Tensorflow. Intro. Data pre-processing is a fundamental part of data scientist work. Apart from data collecting, it is one of the principal stages. On it depends our future model’s quality and accuracy. The better we clean/prepare…
