Model Description

Update February 23 2025: 🔥 BATCHING MODE SUPPORT. See 🌌 Flan-T5 provider for bulk-chain project. Test is available here

Developed by: Reforged by nicolay-r, initial credits for implementation to scofield7419
Model type: Flan-T5
Language(s) (NLP): English
License: Apache License 2.0

Model Sources

Repository: Reasoning-for-Sentiment-Analysis-Framework
Paper: https://arxiv.org/abs/2404.12342
Demo: We have a code on Google-Colab for launching the related model

Uses

Direct Use

Here are the following two steps for a quick start with model application:

Loading model and tokenizer:

python

import torch
from transformers import AutoTokenizer, T5ForConditionalGeneration

# Setup model path.
model_path = "nicolay-r/flan-t5-tsa-prompt-base"
# Setup device.
device = "cuda:0"

model = T5ForConditionalGeneration.from_pretrained(model_path, torch_dtype=torch.bfloat16)
tokenizer = AutoTokenizer.from_pretrained(model_path)
model.to(device)

Setup ask method for generating LLM responses:

python

def ask(prompt):
  inputs = tokenizer(prompt, return_tensors="pt", add_special_tokens=False)
  inputs.to(device)
  output = model.generate(**inputs, temperature=1)
  return tokenizer.batch_decode(output, skip_special_tokens=True)[0]

Finally, you can infer model results as follows:

python

# Input sentence.
sentence = "I would support him"
# Input target.
target = "him"
# output response
flant5_response = ask(f"What's the attitude of the sentence '{context}', to the target '{target}'?")
print(f"Author opinion towards `{target}` in `{sentence}` is:\n{flant5_response}")

The response of the model is as follows:

Author opinion towards "him" in "I would support him despite his bad behavior." is: positive

Downstream Use

Please refer to the related section of the Reasoning-for-Sentiment-Analysis Framework

With this example it applies this model (zero-shot-learning) in the PROMPT mode to the validation data of the RuSentNE-2023 competition for evaluation.

python thor_finetune.py -m "nicolay-r/flan-t5-tsa-prompt-xl" -r "prompt" \
    -p "What's the attitude of the sentence '{context}', to the target '{target}'?" \
    -d "rusentne2023" -z -bs 4 -f "./config/config.yaml"

Following the Google Colab Notebook for implementation reproduction.

Out-of-Scope Use

This model represent a fine-tuned version of the Flan-T5 on RuSentNE-2023 dataset. Since dataset represent three-scale output answers (positive, negative, neutral), the behavior in general might be biased to this particular task.

Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

How to Get Started with the Model

Please proceed with the code from the related Three-Hop-Reasoning CoT section.

Training Details

Training Data

We utilize train data which was automatically translated into English using GoogleTransAPI. The initial source of the texts written in Russian, is from the following repository: https://github.com/dialogue-evaluation/RuSentNE-evaluation

The translated version on the dataset in English could be automatically downloaded via the following script: https://github.com/nicolay-r/Reasoning-for-Sentiment-Analysis-Framework/blob/main/rusentne23_download.py

Training Procedure

This model has been trained using the PROMPT-finetuning.

For training procedure accomplishing, the reforged version of THoR framework

Google-colab notebook could be used for reproduction.

The overall training process took 3 epochs.

Metrics

For the model evaluation, two metrics were used:

F1_PN -- F1-measure over positive and negative classes;
F1_PN0 -- F1-measure over positive, negative, and neutral classes;

Results

The test evaluation for this model showcases the F1_PN = 60.024

Below is the log of the training process that showcases the final peformance on the RuSentNE-2023 test set after 4 epochs (lines 5-6):
