# ner_classifier_v2
This model is a fine-tuned version of [bert-base-uncased](https://huggingface.co/bert-base-uncased) on an unknown dataset.
It achieves the following results on the evaluation set:
- Loss: 0.3338
- F1: 0.8406
## Model description
The DeepNeural NER-II model is designed to identify multiple enitities e.g. people, objects, organization etc. in textual medical documents.
This clinical support model is one of many to be released, and is a crucial aspect of clinical support systems.
## Intended uses & limitations
The model is meant to be used for research and development purposes by Data Scientists, ML & Software Engineers for the development of
NER applications capable of identifying enitities in medical EHR systems to augment patient health processing.
