Training procedure

The run_clm.py script from the transformers library was used. Training was distributed on two NVIDIA Quadro RTX 6000 GPUs:

Training results

Evaluation results

Perplexity on random 2000 examples of the target language's Wikipedia dataset, using the code provided in the perplexity docs, with 512 tokes of stride. Baseline is the result from evaluating OpenAI's GPT-2 on the same examples.

The following script was used for evaluation

import numpy as np
from datasets import load_dataset
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
from tqdm import tqdm
import random

# Set the seed for reproducibility
random.seed(42)

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

# Load the model
model_name = "RaiBP/gpt2-openwebtext2-first-30-chunks-ablation-bilingual"
model = AutoModelForCausalLM.from_pretrained(model_name).to(device)
tokenizer = AutoTokenizer.from_pretrained(model_name)

target_language_dataset = "20231101.de" # change here for other languages

dataset = load_dataset("wikimedia/wikipedia", target_language_dataset, split="train")
num_examples = 2000
random_numbers = list(np.random.randint(0, len(dataset), num_examples))
examples = []
for i in tqdm(random_numbers):
    examples.append(dataset[int(i)]["text"])
encodings = tokenizer("\n\n".join(examples), return_tensors="pt")

max_length = model.config.n_positions
stride = 512
seq_len = encodings.input_ids.size(1)

nlls = []
prev_end_loc = 0
for begin_loc in tqdm(range(0, seq_len, stride)):
    end_loc = min(begin_loc + max_length, seq_len)
    trg_len = end_loc - prev_end_loc  # may be different from stride on last loop
    input_ids = encodings.input_ids[:, begin_loc:end_loc].to(device)
    target_ids = input_ids.clone()
    target_ids[:, :-trg_len] = -100

    with torch.no_grad():
        outputs = model(input_ids, labels=target_ids)

        # loss is calculated using CrossEntropyLoss which averages over valid labels
        # N.B. the model only calculates loss over trg_len - 1 labels, because it internally shifts the labels
        # to the left by 1.
        neg_log_likelihood = outputs.loss

    nlls.append(neg_log_likelihood)

    prev_end_loc = end_loc
    if end_loc == seq_len:
        break

ppl = torch.exp(torch.stack(nlls).mean())

print("Perplexity: ", ppl.item())
