Model description

This adapter model is a fine-tuned version of DAMO-NLP-MT/polylm-1.7b. It achieves the following results on the evaluation set:

  • Loss: 1.8483

Finetuning was performed on the Dutch BramVanroy/alpaca-cleaned-dutch dataset which contains 52K of records with instruction following-data translated from English to Dutch.

See DAMO-NLP-MT/polylm-1.7b for all information about the base model.

Model usage

A basic example of how to use the finetuned model.

import torch
from peft import AutoPeftModelForCausalLM
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "robinsmits/polylm_1.7b_ft_alpaca_clean_dutch"

tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast = False, legacy = False)

model = AutoPeftModelForCausalLM.from_pretrained(model_name, device_map = "auto", load_in_4bit = True, torch_dtype = torch.bfloat16)

prompt = "### Instructie:\nWat zijn de drie belangrijkste softwareonderdelen die worden gebruikt bij webontwikkeling?\n\n### Antwoord:\n" 

inputs = tokenizer(prompt, return_tensors = "pt")
sample = model.generate(input_ids = inputs.input_ids.cuda(),
                        attention_mask = inputs.attention_mask.cuda(),
                        max_new_tokens = 128,
                        do_sample = True,
                        top_p = 0.85,
                        top_k = 50,
                        temperature = 0.5,
                        repetition_penalty = 1.2,
                        length_penalty = -1.0,
                        num_return_sequences = 1,
                        pad_token_id = tokenizer.eos_token_id,
                        forced_eos_token_id = tokenizer.eos_token_id)
output = tokenizer.decode(sample[0], skip_special_tokens = True)


The prompt and generated output for the above mentioned example is similar to the output shown below.

### Instructie:
Wat zijn de drie belangrijkste softwareonderdelen die worden gebruikt bij webontwikkeling?

### Antwoord:

De drie belangrijkste softwareonderdelen die worden gebruikt in webontwikkeling zijn HTML, CSS en Javascript.HTML is het hoofdbestand voor alle inhoud op een website.CSS is het hoofdbestand voor decoraties en scripts om te gebruiken zoals JavaScript en PHP.Javascript wordt meestal gebruikt om verschillende functies uit te voeren of het script te manipuleren.Het laatste bestand maakt het mogelijk om code te schrijven dat aan uw website gekoppeld kan worden door middel van enkele woorden. Daarnaast kunnen er ook andere bestanden nodig zijn als gevolg van gebruik van meerdere servers.Een voorbeeld hiervan zou zijn wanneer u bijvoorbeeld een blog-website

Intended uses & limitations

The PolyLM-1.7B model was trained on 18 languages. The primary focus was to create a multi-lingual Open LLM. Dutch was one of those 18 languages. For training the model a diverse combination of multi-lingual datasets was used.

The generated output and performance of this model for the Dutch language is very likely not always comparable to the various Open-Llama models that have been finetuned on English Alpaca datasets.

The primary intention of this finetuned model is to explore and research the use of the Dutch language in combination with an Open LLM model.

Bias, Risks, and Limitations

The information below is copied from the base model's official model card: This applies also to the finetuned model.

Our contributions are fully methodological: adding the support of multilingualism to LLM during training and SFT phases. It is unavoidable that PolyLM might exhibit several common deficiencies of language models, e.g. hallucination and toxicity. PolyLM should not be used directly in any application, without a prior assessment of safety and fairness concerns specific to the application.

Training and evaluation data

This model was trained on the BramVanroy/alpaca-cleaned-dutch dataset.

The dataset is the Dutch translation of the English Alpaca Cleaned instruction dataset.

Based on the dataset license only Non-Commercial use is allowed. Commercial use is strictly forbidden.
