## Modeling Emotional Trajectories in Written Stories

<!-- Provide a quick summary of what the model is/does. -->

This model is intended to predict emotions (valence, arousal) in written stories. For all details see [the paper](http://arxiv.org/abs/2406.02251) and [the accompanying github repo](https://github.com/lc0197/emotional_trajectories_stories).



### Model Description

<!-- Provide a longer summary of what this model is. -->

As described in [the paper](http://arxiv.org/abs/2406.02251), this model is finetuned from [DeBERTaV3-large](https://huggingface.co./microsoft/deberta-v3-large) and predicts sentence-wise valence/arousal values between 0 and 1. 

This particular checkpoint was trained with a window size of 2. 

All available checkpoints and their performance measured by Concordance Correlation Coefficient (CCC):

| Model                                                                  | Valence dev/test   | Arousal dev/test   |
|------------------------------------------------------------------------|--------------------|--------------------|
|[stories-emotion-c0](https://huggingface.co./chrlukas/stories-emotion-c0)| .7091/.7187        | .5815/.6189        |
|[stories-emotion-c1](https://huggingface.co./chrlukas/stories-emotion-c1)| .7715/.7875        | .6458/.6935        |
|[stories-emotion-c2](https://huggingface.co./chrlukas/stories-emotion-c2)| .7922/.8074        | .6667/.6954        |
|[stories-emotion-c4](https://huggingface.co./chrlukas/stories-emotion-c4)| .8078/.8146        | .6763/.7115        |
|[stories-emotion-c8](https://huggingface.co./chrlukas/stories-emotion-c8)| **.8223**/**.8237**| **.6829**/**.7120**|

We provide the best out of 5 seeds for each context size. Hence, the numbers in this table differ from the result table in the paper, where the mean performance across 5 seeds is reported.

Technically, this model predicts token-wise valence/arousal values. Sentences are concatenated via the ``[SEP]`` token, where the valence/arousal predictions for an ``[SEP]`` token
are meant to be the predictions for the sentence preceding it. All other tokens' predictions should be ignored. For reference, see the figure in the paper:
