Overview of Conditional Random Fields - Medium

Nettet6. mar. 2024 · CRF (Conditional Random Fields) has been a popular supervised learning method before deep learning occurred, and still, it is a easy-to-use and robust machine learning algorithm. We recently used this algorithm to do NER (name entity recognition), and here is a brief summary of using CRF in Python. Introduction of CRF Nettet3. jan. 2024 · In the machine learning methods for extracting basic mathematical knowledge points, the Conditional Random Field (CRF) model implements new word discovery well, and is increasingly used in knowledge extraction of basic mathematics.

Less rigid requirements for the input data. If you are looking for Python bindings CRFSuite is also better because you can train a model in Python, while in CRF++ you can only test existing models in Python. (That was the deal breaker for me.)
