disham993 / electrical-classification-bert-base

electrical-classification-bert-base-uncased

Model description

This model is fine-tuned from google-bert/bert-base-uncased for text classification tasks, specifically sentiment analysis of customer feedback on electrical devices - circuit breakers, transformers, smart meters, inverters, solar panels, power strips etc. The model has been optimized to classify sentiments into categories such as Positive, Negative, Neutral, and Mixed with high f1 and accuracy scores, making it ideal for analyzing product reviews, customer surveys, and other feedback to derive actionable insights.

Training Data

The model was trained on the disham993/ElectricalDeviceFeedbackBalanced dataset, which has been carefully balanced to address class imbalances effectively. Original dataset which is imbalanced: disham993/ElectricalDeviceFeedback .

Usage

You can use this model for Sentiment Analysis of the Electrical Device Feedback as follows:

from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline

model_name = "disham993/electrical-classification-bert-base"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
nlp = pipeline("text-classification", model=model, tokenizer=tokenizer)

text = "The new washing machine is efficient but produces a bit of noise."
classification_results = nlp(text)
print(classification_results)

Limitations and bias

The dataset includes synthetic data generated using Llama 3.1:8b, and despite careful optimization and prompt engineering, the model is not immune to errors in labeling. Additionally, as LLM technology is still in its early stages, there may be inherent inaccuracies or biases in the generated data that can impact the model's performance.

This model is intended for research and educational purposes only, and users are encouraged to validate results before applying them to critical applications.
