# Model Overview:
|
| 16 |
+
The model is a language generation model designed for extending the GPT2 models to support Hindi language along with the original languages that it supports. It was fine-tuned on Hindi texts of [wikipedia](https://www.kaggle.com/datasets/disisbig/hindi-wikipedia-articles-55k) articles.
|
| 17 |
+
|
| 18 |
+
# Model Architecture and Parameters:
|
| 19 |
+
The model architecture is based on the GPT-2 framework, specifically using the parameters of the small version of the original OpenAI GPT2 model. It employs a Byte Pair Encoding (BPE) tokenizer.
|
| 20 |
+
|
| 21 |
+
# Corpus:
|
| 22 |
+
The training corpus for Hindi GPT2 consists of Wikipedia articles.
|
| 23 |
+
|
| 24 |
+
# Tokenizer:
|
| 25 |
+
A tokenizer is trained on Hindi Wikipedia Corpus. The new tokenizer vocabulary (5000 tokens) is merged with existing tokenizer. Hindi GPT2 uses a byte-level version of Byte Pair Encoding (BPE) for tokenizing Hindi text, including Unicode characters. The tokenizer has a vocabulary size of 53497, which allows it to effectively represent the Hindi language's rich vocabulary. Input sequences are formed by breaking the text into consecutive tokens with a maximum length of 1024 tokens.
