+
- **Model type:** gptj
|
27 |
+
- **Language(s) (NLP):** de
|
28 |
+

# Uses
|
32 |
+
|
33 |
+
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
|
34 |
+
|
35 |
+
This model is not intended for use! It is a preliminary version of gptj-title-teaser-10k to prove the multitask fine-tuning approach.
|
36 |
+
For use please refer to [gptj-title-teaser-10k](https://huggingface.co/snipaid/gptj-title-teaser-10k).

# Training Details
|

+
|
41 |
+
## Training Data
|
42 |
+
|
43 |
+
<!-- This should link to a Data Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->
|
44 |
+
|
45 |
+
The model was finetuned on a collection of 1,000 news items scraped from different online news outlets in german language.
|
46 |
+
|
47 |
+
For each news item the dataset contains title, teaser and fulltext.
|
48 |
+
|
49 |
+
```
|
50 |
+
[
|
51 |
+
{
|
52 |
+
"title": ...,
|
53 |
+
"teaser": ...,
|
54 |
+
"fulltext": ...
|
55 |
+
},
|
56 |
+
]
|
57 |
+
```
|
58 |
+
|
59 |
+
## Training Procedure
|
60 |
+
|
61 |
+
<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->
|
62 |
+
|
63 |
+
The model was finetuned using a causal language modeling (CLM) objective for multitask finetuning.
|
64 |
+
|
65 |
+
### Preprocessing
|
66 |
+
|
67 |
+
For each news item, two inputs were concatenated like below.
|
68 |
+
```
|
69 |
+
f"[Text]: {item.fulltext} \n [Title]: {item.title}"
|
70 |
+
f"[Text]: {item.fulltext} \n [Teaser]: {item.teaser}"
|
71 |
+
```
|
72 |
+
This results in one input per task for each news item.
|
73 |
+
|
74 |
+
*Note: The inserted prompt "[Text]:" marks the beginning of the news item's fulltext.
|
75 |
+
In the same manner "[Title]:" prompts the news item's title and "[Teaser]:" the news item's teaser.*
|
76 |
+
|
77 |
+
# Evaluation
|
78 |
+
|
79 |
+
1,000 german news articles proved to be sufficient to validate the approach.
|
80 |
+
Evaluation showed that the model improved compared to the GPT-J baseline in:
|
81 |
+
- german language capabilities (significantly)
|
82 |
+
- title generation (significantly)
|
83 |
+
- teaser generation (slightly)
|
84 |
+
|
85 |
+
The evaluation also suggested that there is still opportunity for improvement with more data.
|
86 |
+
For the model trained with the same approach but 10x the amount of data pleaser refer to [gptj-title-teaser-10k](https://huggingface.co/snipaid/gptj-title-teaser-10k).

+
<!-- Total emissions (in grams of CO2eq) and additional considerations, such as electricity usage, go here. Edit the suggested text below accordingly -->
|
91 |
+
|
