Beginner friendly tutorial for understanding what label propagation for semi-supervised learning is and learn how to use it for both tabular and text data — Introduction What is semi-supervised learning? As the name suggests, semi-supervised learning lies somewhere between supervised and unsupervised learning. Supervised learning in machine learning refers to the classical models we encounter where we have training data each data point labeled (in a classification problem setting) and a model is trained using that…

Take a look at the medspaCy Python package, an open source package effective for performing various NLP tasks when ti comes to medical and health related text data. — Introduction Named Entity Recognition (NER) is a kind of Natural Language Processing (NLP) task that tags entities in text with their corresponding type. Many algorithms and open source packages that implemented them are already available for data scientists and researchers to use. One such example would be Python’s SpaCy package. However…

Learn about the SOTA model for topic modeling — Introduction Topic modeling is a type of Natural Language Processing (NLP) task that utilizes unsupervised learning methods to extract out the main topics of some text data we deal with. The word “Unsupervised” here means that there are no training data that have associated topic labels. …
