| ## Emo-MobileBERT: a thin version of BERT LARGE, trained on the EmoContext Dataset from scratch |
|
|
| ### Details of MobileBERT |
|
|
| The **MobileBERT** model was presented in [MobileBERT: a Compact Task-Agnostic BERT for Resource-Limited Devices](https://arxiv.org/abs/2004.02984) by *Zhiqing Sun, Hongkun Yu, Xiaodan Song, Renjie Liu, Yiming Yang, Denny Zhou* and here is the abstract: |

| Natural Language Processing (NLP) has recently achieved great success by using huge pre-trained models with hundreds of millions of parameters. However, these models suffer from heavy model sizes and high latency such that they cannot be deployed to resource-limited mobile devices. In this paper, we propose MobileBERT for compressing and accelerating the popular BERT model. Like the original BERT, MobileBERT is task-agnostic, that is, it can be generically applied to various downstream NLP tasks via simple fine-tuning. Basically, MobileBERT is a thin version of BERT_LARGE, while equipped with bottleneck structures and a carefully designed balance between self-attentions and feed-forward networks. To train MobileBERT, we first train a specially designed teacher model, an inverted-bottleneck incorporated BERT_LARGE model. Then, we conduct knowledge transfer from this teacher to MobileBERT. Empirical studies show that MobileBERT is 4.3x smaller and 5.5x faster than BERT_BASE while achieving competitive results on well-known benchmarks. On the natural language inference tasks of GLUE, MobileBERT achieves a GLUEscore o 77.7 (0.6 lower than BERT_BASE), and 62 ms latency on a Pixel 4 phone. On the SQuAD v1.1/v2.0 question answering task, MobileBERT achieves a dev F1 score of 90.0/79.2 (1.5/2.1 higher than BERT_BASE). |

| |
| SemEval-2019 Task 3: EmoContext Contextual Emotion Detection in Text |
| |
| In this dataset, given a textual dialogue i.e. an utterance along with two previous turns of context, the goal was to infer the underlying emotion of the utterance by choosing from four emotion classes: |
| |
| - sad 😢 |
| - happy 😃 |
| - angry 😡 |
| - others |
| |
| ### Model training |
| |
| The training script is present [here](https://github.com/lordtt13/transformers-experiments/blob/master/Custom%20Tasks/emo-mobilebert.ipynb). |
| |
| ### Pipelining the Model |
| |
| ```python |
| from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline |
| |
| tokenizer = AutoTokenizer.from_pretrained("lordtt13/emo-mobilebert") |
|
|
| model = AutoModelForSequenceClassification.from_pretrained("lordtt13/emo-mobilebert") |
| |
| nlp_sentence_classif = transformers.pipeline('sentiment-analysis', model = model, tokenizer = tokenizer) |
| nlp_sentence_classif("I've never had such a bad day in my life") |
| # Output: [{'label': 'sad', 'score': 0.93153977394104}] |
| ``` |
