# tner/deberta-v3-large-mit-restaurant

This model is a fine-tuned version of [microsoft/deberta-v3-large](https://huggingface.co/microsoft/deberta-v3-large) on the 
[tner/mit_restaurant](https://huggingface.co/datasets/tner/mit_restaurant) dataset.
Model fine-tuning is done via [T-NER](https://github.com/asahi417/tner)'s hyper-parameter search (see the repository
for more detail). It achieves the following results on the test set:
- F1 (micro): 0.8158890290037831
- Precision (micro): 0.8105230191042906
- Recall (micro): 0.8213265629958744
- F1 (macro): 0.8072607717138172
- Precision (macro): 0.7973293573334044
- Recall (macro): 0.8183493118743246

The per-entity breakdown of the F1 score on the test set are below:
- amenity: 0.7226415094339623
- cuisine: 0.8288119738072967
- dish: 0.8283828382838284
- location: 0.8662969808995686
- money: 0.84
- rating: 0.7990430622009569
- restaurant: 0.8724489795918368
- time: 0.7004608294930875 

For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro): 
    - 90%: [0.8036180555961564, 0.8281173227233776]
    - 95%: [0.8011397826491581, 0.8307029010155984] 
- F1 (macro): 
    - 90%: [0.8036180555961564, 0.8281173227233776]
    - 95%: [0.8011397826491581, 0.8307029010155984] 

Full evaluation can be found at [metric file of NER](https://huggingface.co/tner/deberta-v3-large-mit-restaurant/raw/main/eval/metric.json) 
and [metric file of entity span](https://huggingface.co/tner/deberta-v3-large-mit-restaurant/raw/main/eval/metric_span.json).

### Usage
This model can be used through the [tner library](https://github.com/asahi417/tner). Install the library via pip   
```shell
pip install tner
```
and activate model as below.
```python
from tner import TransformersNER
model = TransformersNER("tner/deberta-v3-large-mit-restaurant")
model.predict(["Jacob Collier is a Grammy awarded English artist from London"])
```
It can be used via transformers library but it is not recommended as CRF layer is not supported at the moment.

### Training hyperparameters

The following hyperparameters were used during training:
 - dataset: ['tner/mit_restaurant']
 - dataset_split: train
 - dataset_name: None
 - local_dataset: None
 - model: microsoft/deberta-v3-large
 - crf: True
 - max_length: 128
 - epoch: 15
 - batch_size: 16
 - lr: 1e-05
 - random_seed: 42
 - gradient_accumulation_steps: 4
 - weight_decay: 1e-07
 - lr_warmup_step_ratio: 0.1
 - max_grad_norm: None

The full configuration can be found at [fine-tuning parameter file](https://huggingface.co/tner/deberta-v3-large-mit-restaurant/raw/main/trainer_config.json).

    abstract = "Language model (LM) pretraining has led to consistent improvements in many NLP downstream tasks, including named entity recognition (NER). In this paper, we present T-NER (Transformer-based Named Entity Recognition), a Python library for NER LM finetuning. In addition to its practical utility, T-NER facilitates the study and investigation of the cross-domain and cross-lingual generalization ability of LMs finetuned on NER. Our library also provides a web app where users can get model predictions interactively for arbitrary text, which facilitates qualitative model evaluation for non-expert programmers. We show the potential of the library by compiling nine public NER datasets into a unified format and evaluating the cross-domain and cross- lingual performance across the datasets. The results from our initial experiments show that in-domain performance is generally competitive across datasets. However, cross-domain generalization is challenging even with a large pretrained LM, which has nevertheless capacity to learn domain-specific features if fine- tuned on a combined dataset. To facilitate future research, we also release all our LM checkpoints via the Hugging Face model hub.",
