haloop

Haloop is a speech agent toolkit. Haloop provides:

• hai program to initialize models;
• hac program for acoustic model training;
• hal for RNN language model training and evaluation;
• hala for causal attention model training;
• hat for agent testing.

The package can be installed from PyPI:

pip install haloop

Pretrained models

hat can be used with Ukrainian GPT-2 models from our paper GPT-2 Metadata Pretraining Towards Instruction Finetuning for Ukrainian.

You will need to install and download:

pip install bitsandbytes sentencepiece

wget https://a.wilab.org.ua/gpt/wiki.model  # sentencepiece tokenizer
wget https://a.wilab.org.ua/gpt/ckpt10m.pt  # model checkpoint for GPT-2 Large

Now, kick off the REPL:

hat --spm wiki.model ckpt10m.pt

We enrich document text by surrounding it with weakly structured metadata, such as title, tags, and publication year, enabling metadata-conditioned text generation and text-conditioned metadata prediction at the same time. We pretrain GPT-2 Small, Medium and Large models each on single GPU, reporting training times, BPC on BrUK and BERTScore on titles for 1000 News from the Future. Next, we venture to formatting POS and NER datasets as instructions, and train low-rank attention adapters, performing these tasks as constrained text generation. We release our models for the community at https://github.com/proger/uk4b.",
