| # TransformationTransformer |
|
|
| **TransformationTransformer** is a fine-tuned [distilroberta](https://huggingface.co/distilroberta-base) model. It is trained and evaluated on 10,000 manually annotated sentences gleaned from the Q&A-section of quarterly earnings conference calls. In particular, it was trained on sentences issued by firm executives to discriminate between setnences that allude to **business transformation** vis-à-vis those that discuss topics other than business transformations. More details about the training procedure can be found [below](#model-training). |

|
| ## Background |
|
|
| Context on the project. |
|
|
|
|
| ## Usage |
|
|
| The model is intented to be used for sentence classification: It creates a contextual text representation from the input sentence and outputs a probability value. `LABEL_1` refers to a sentence that is predicted to contains transformation-related content (vice versa for `LABEL_0`). The query should consist of a single sentence. |
|
|
|
|
| ## Usage (API) |
|
|
| ```python |
| import json |
| import requests |
| |
| API_TOKEN = <TOKEN> |
| |
| headers = {"Authorization": f"Bearer {API_TOKEN}"} |
| API_URL = "https://api-inference.huggingface.co/models/simonschoe/call2vec" |
| |
| def query(payload): |
| data = json.dumps(payload) |
| response = requests.request("POST", API_URL, headers=headers, data=data) |
| return json.loads(response.content.decode("utf-8")) |
| |
| query({"inputs": "<insert-sentence-here>"}) |
| ``` |
|
|
| ## Usage (transformers) |
|
|
| ```python |
| from transformers import AutoTokenizer, AutoModelForSequenceClassification |
| |
| tokenizer = AutoTokenizer.from_pretrained("simonschoe/TransformationTransformer") |
| model = AutoModelForSequenceClassification.from_pretrained("simonschoe/TransformationTransformer") |
| |
| classifier = pipeline('text-classification', model=model, tokenizer=tokenizer) |
| classifier('<insert-sentence-here>') |
| ``` |
|
|
|
|
| ## Model Training |
|
|
| The model has been trained on text data stemming from earnings call transcripts. The data is restricted to a call's question-and-answer (Q&A) section and the remarks by firm executives. The data has been segmented into individual sentences using [`spacy`](https://spacy.io/). |
|
|
| **Statistics of Training Data:** |
| - Labeled sentences: 10,000 |
| - Data distribution: xxx |
| - Inter-coder agreement: xxx |
