Limitations
Current Model is a powerful tool for machine translation, but it’s not perfect. Let’s take a closer look at some of its limitations.
Language Limitations
- Current Model is trained on a specific set of languages, which means it may not perform well on languages outside of this set.
- Even within the supported languages, Current Model may struggle with dialects or regional variations.
Data Limitations
- Current Model is only as good as the data it’s trained on. If the training data contains biases or inaccuracies, the model may learn and replicate these flaws.
- The model may not have seen enough data on certain topics or domains, which can affect its performance.
Complexity Limitations
- Current Model can struggle with complex or nuanced texts, such as those with multiple layers of meaning or subtle implications.
- The model may not always be able to capture the context or tone of a piece of text, which can lead to misunderstandings.
Technical Limitations
- Current Model requires significant computational resources to run, which can make it difficult to use on lower-end hardware.
- The model may not be compatible with all platforms or software, which can limit its usability.
Format
IndicTrans2 is a powerful AI model that uses a transformer architecture to process and generate text. But what does that mean for you?
Architecture
IndicTrans2 is a sequence-to-sequence model, which means it takes in a sequence of text (like a sentence or a paragraph) and generates another sequence of text as output. This is perfect for tasks like machine translation, where you want to convert text from one language to another.
Data Formats
IndicTrans2 supports input and output in various formats, including:
- Text sequences (like sentences or paragraphs)
- Tokenized text (where each word or character is represented as a unique token)
Special Requirements
To use IndicTrans2, you’ll need to preprocess your input text using the IndicProcessor from the IndicTransToolkit. This step is important because it helps the model understand the structure and meaning of the input text.
Here’s an example of how to preprocess a batch of input sentences:
input_sentences = [
"जब मैं छोटा था, मैं हर रोज़ पार्क जाता था।",
"हमने पिछले सप्ताह एक नई फिल्म देखी जो कि बहुत प्रेरणादायक थी।",
"अगर तुम मुझे उस समय पास मिलते, तो हम बाहर खाना खाने चलते।",
"मेरे मित्र ने मुझे उसके जन्मदिन की पार्टी में बुलाया है, और मैं उसे एक तोहफा दूंगा।"
]
src_lang, tgt_lang = "hin_Deva", "eng_Latn"
batch = ip.preprocess_batch(input_sentences, src_lang=src_lang, tgt_lang=tgt_lang)
Once you’ve preprocessed your input text, you can use the AutoTokenizer from the transformers library to tokenize the text and generate input encodings.
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
inputs = tokenizer(batch, truncation=True, padding="longest", return_tensors="pt", return_attention_mask=True).to(DEVICE)
Finally, you can use the IndicTrans2 model to generate translations:
model = AutoModelForSeq2SeqLM.from_pretrained(model_name, trust_remote_code=True)
with torch.no_grad():
generated_tokens = model.generate(**inputs, use_cache=True, min_length=0, max_length=256, num_beams=5, num_return_sequences=1)
And that’s it! With these steps, you can use IndicTrans2 to generate high-quality translations for a variety of languages.
