Emotion Recognition in Coversation (ERC)

At the moment, we only use the text modality to correctly classify the emotion of the utterances.The experiments were carried out on two datasets (i.e. MELD and IEMOCAP)

Watch a demo video!

Prerequisites

1. An x86-64 Unix or Unix-like machine
2. Python 3.8 or higher
3. Running in a virtual environment (e.g., conda, virtualenv, etc.) is highly recommended so that you don't mess up with the system python.
4. multimodal-datasets repo (submodule)
5. pip install -r requirements.txt

EmoBERTa training

First configure the hyper parameters and the dataset in train-erc-text.yaml and then, In this directory run the below commands. I recommend you to run this in a virtualenv.

python train-erc-text.py

This will subsequently call train-erc-text-hp.py and train-erc-text-full.py.

Results on the test split (weighted f1 scores)

Model		MELD	IEMOCAP
EmoBERTa	No past and future utterances	63.46	56.09
	Only past utterances	64.55	68.57
	Only future utterances	64.23	66.56
	Both past and future utterances	65.61	67.42
	→ without speaker names	65.07	64.02

Above numbers are the mean values of five random seed runs.

If you want to download the trained checkpoints and stuff, then here is where you can download them. It's a pretty big zip file.

Deployment

Huggingface

We have released our models on huggingface:

• emoberta-base
• emoberta-large

They are based on RoBERTa-base and RoBERTa-large, respectively. They were trained on both MELD and IEMOCAP datasets. Our deployed models are neither speaker-aware nor take previous utterances into account, meaning that it only classifies one utterance at a time without the speaker information (e.g., "I love you").

Flask app

You can either run the Flask RESTful server app as a docker container or just as a python script.

1. Running the app as a docker container (recommended).

   There are four images. Take what you need:

   • docker run -it --rm -p 10006:10006 tae898/emoberta-base
   • docker run -it --rm -p 10006:10006 --gpus all tae898/emoberta-base-cuda
   • docker run -it --rm -p 10006:10006 tae898/emoberta-large
   • docker run -it --rm -p 10006:10006 --gpus all tae898/emoberta-large-cuda

2. Running the app in your python environment:

   This method is less recommended than the docker one.

   Run pip install -r requirements-deploy.txt first.
   The app.py is a flask RESTful server. The usage is below:

   app.py [-h] [--host HOST] [--port PORT] [--device DEVICE] [--model-type MODEL_TYPE]

   For example:

   python app.py --host 0.0.0.0 --port 10006 --device cpu --model-type emoberta-base

Client

Once the app is running, you can send a text to the server. First install the necessary packages: pip install -r requirements-client.txt, and the run the client.py. The usage is as below:

client.py [-h] [--url-emoberta URL_EMOBERTA] --text TEXT

For example:

python client.py --text "Emotion recognition is so cool\!"

will give you:

{
  "neutral": 0.0049800905,
  "joy": 0.96399665,
  "surprise": 0.018937444,
  "anger": 0.0071516023,
  "sadness": 0.002021492,
  "disgust": 0.001495996,
  "fear": 0.0014167271
}
