🌐 Language Detector Model

This project is a Language Detection Model built in Python.
It loads and cleans a multilingual text dataset, trains a machine learning model, and allows users to test language predictions on custom input.

The model uses TF-IDF Vectorization and Logistic Regression to classify text into its respective language.
Additionally, the project includes data cleaning, model evaluation, and visualization of results.
