+ # Conditional Utilitarian Deberta 01
12
+
13
+ ## Model description
14
+
15
+ This is a [Deberta-based](https://huggingface.co/microsoft/deberta-v3-large) model. It was first fine-tuned on for computing utility estimates of experiences (see [utilitarian-deberta-01](https://huggingface.co/pfr/utilitarian-deberta-01). It was then further fine-tuned on 160 examples of conditional utilities pairwise comparisons.
16
+
17
+ ## Intended use
18
+
19
+ The main use case is the computation of utility estimates of first-person text scenarios, under extra contextual information.
20
+
21
+ ## Limitations
22
+
23
+ The model was fine-tuned on only 160 examples, so it should be expected to have limited performance.
24
+
25
+ Further, while the base model was trained on ~10000 examples, they are still restricted, and only on first-person sentences. It does not have the capability of interpreting highly complex or unusual scenarios, and it does not have hard guarantees on its domain of accuracy.
26
+
27
+ ## How to use
28
+
29
+ Given a scenario S under a context C, and the model U, one computes the estimated conditional utility with `U(f'{C} {S}') - U(C)`.
30
+
31
+ ## Training data
32
+
33
+ The first training data is the train split from the Utilitarianism part of the [ETHICS dataset](https://arxiv.org/abs/2008.02275).
34
+
35
+ The second training data consists of 160 crowdsourced examples of triples (S, C0, C1) consisting of one scenario and two possible contexts, where `U(S | C0) > U(S | C1)`.
36
+
37
+ ## Training procedure
38
+
39
+ Starting from [utilitarian-deberta-01](https://huggingface.co/pfr/utilitarian-deberta-01), we fine-tune the model over the training data of 160 examples, with a learning rate of `1e-5`, a batch size of `8`, and `nepochs` of 2.
40
+
41
+ ## Evaluation results
42
+
43
+ The model achieves ~80% accuracy over 40 crowdsourced examples, from the same distribution as the training data.
