# Mobile App Classification |
|
|
|
## Model description |
|
|
|
DistilBERT is a transformers model, smaller and faster than BERT, which was pre-trained on the same corpus in a self-supervised fashion, using the BERT base model as a teacher. |
|
|
|
The [distilbert-base-uncased](https://huggingface.co/distilbert-base-uncased) model is fine-tuned to classify an mobile app description into one of **6 play store categories**. |
|
Trained on 9000 samples of English App Descriptions and associated categories of apps available in [Google Play](https://play.google.com/store/apps). |
|
|
|
## Fine-tuning |
|
|
|
The model was fine-tuned for 5 epochs with a batch size of 16, a learning rate of 2e-05, and a maximum sequence length of 512. Since this was a classification task, the model was trained with a cross-entropy loss function. The best evaluation f1 score achieved by the model was 0.9034534096919489, found after 4 epochs. The accuracy of the model on the test set was 90.33. |
|
|
|
## How to use |
|
|
|
```python |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("nsi319/distilbert-base-uncased-finetuned-app") |
|
model = AutoModelForSequenceClassification.from_pretrained("nsi319/distilbert-base-uncased-finetuned-app") |
|
|
|
classifier = pipeline('sentiment-analysis', model=model, tokenizer=tokenizer) |
|
|
|
classifier("From scores to signings, the ESPN App is here to keep you updated. Never miss another sporting moment with up-to-the-minute scores, latest news & a range of video content. Sign in and personalise the app to receive alerts for your teams and leagues. Wherever, whenever; the ESPN app keeps you connected.") |
|
|
|
'''Output''' |
|
[{'label': 'Sports', 'score': 0.9959789514541626}] |
|
``` |
|
|
|
## Limitations |
|
Training data consists of apps from 6 play store categories namely Education, Entertainment, Productivity, Sports, News & Magazines and Photography. |
