Model Details

Model Description

An MT5Tokenizer based Amharic and English tokenizer trained using Fineweb and Wura datasets. This tokenizer aims to have a tokenizer that can better represent Amharic while also doing the same for English. To balance the dataset, I have used only 3 million document samples from the dataset. The vocabulary size of this tokenizer is the same as google/mt5-small.

MT5 Tokenizer Vs AmhT5 Tokenizer

python

from transformers import MT5TokenizerFast

mt5 = "google/mt5-small"

TOKENIZER = MT5TokenizerFast.from_pretrained(mt5, legacy=False)
tokens = TOKENIZER.tokenize("ከመዲናዋ በቅርብ ርቀት ላይ በምትገኘው ከተማ")

print(len(tokens)) # 20
print(tokens)
# ['▁ከመ', 'ዲ', 'ና', 'ዋ', '▁በ', 'ቅር', 'ብ', '▁', 'ር', 'ቀ', 'ት', '▁', 'ላይ', '▁በም', 'ት', 'ገ', 'ኘ', 'ው', '▁ከተ', 'ማ']


tokens = TOKENIZER.tokenize("A Tokenizer trained for Amharic language.")

print(len(tokens)) # 11
print(tokens)
# ['▁A', '▁', 'Token', 'izer', '▁train', 'ed', '▁for', '▁Am', 'haric', '▁language', '.']


amhT5 = "yonas/AmhT5-tokenizer"
TOKENIZER = MT5TokenizerFast.from_pretrained(amhT5, legacy=False)
tokens = TOKENIZER.tokenize("ከመዲናዋ በቅርብ ርቀት ላይ በምትገኘው ከተማ")

print(len(tokens)) # 11
print(tokens)
# ['▁ከ', 'መዲና', 'ዋ', '▁በ', 'ቅርብ', '▁', 'ርቀት', '▁ላይ', '▁በምት', 'ገኘው', '▁ከተማ']

print(len(tokens)) # 7
