ProgressGym-HistLlama3-8B-C021-pretrain

Overview

The ProgressGym Framework

ProgressGym-HistLlama3-8B-C021-pretrain is part of the ProgressGym framework for research and experimentation on progress alignment - the emulation of moral progress in AI alignment algorithms, as a measure to prevent risks of societal value lock-in.

To quote the paper ProgressGym: Alignment with a Millennium of Moral Progress:

Frontier AI systems, including large language models (LLMs), hold increasing influence over the epistemology of human users. Such influence can reinforce prevailing societal values, potentially contributing to the lock-in of misguided moral beliefs and, consequently, the perpetuation of problematic moral practices on a broad scale.

We introduce progress alignment as a technical solution to mitigate this imminent risk. Progress alignment algorithms learn to emulate the mechanics of human moral progress, thereby addressing the susceptibility of existing alignment methods to contemporary moral blindspots.

ProgressGym-HistLlama3-8B-C021-pretrain

ProgressGym-HistLlama3-8B-C021-pretrain is one of the 36 historical language models in the ProgressGym framework. It is a pretrained model without instruction-tuning. For the instruction-tuned version, see ProgressGym-HistLlama3-8B-C021-instruct.

ProgressGym-HistLlama3-8B-C021-pretrain is under continual iteration. Improving upon the current version, new versions of the model are currently being trained to reflect historical moral tendencies in ever more comprehensive ways.

ProgressGym-HistLlama3-8B-C021-pretrain is a 21st-century historical language model. Based on Meta-Llama-3-8B, It is continued-pretrained on the 21st-century text data from ProgressGym-HistText, using the following hyperparameters:

• learning_rate: 1.5e-05
• train_batch_size: 4
• eval_batch_size: 8
• seed: 42
• distributed_type: multi-GPU
• num_devices: 8
• total_train_batch_size: 32
• total_eval_batch_size: 64
• optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
• lr_scheduler_type: polynomial
• lr_scheduler_warmup_steps: 20
• num_epochs: 4.0
• mixed_precision_training: Native AMP

... with the following training results:

Training Loss	Epoch	Step	Validation Loss
1.2572	0.4264	200	1.2612
1.1754	0.8529	400	1.2226
1.1662	1.2793	600	1.2202
1.1182	1.7058	800	1.2184
1.046	2.1322	1000	1.2190
1.0772	2.5586	1200	1.2190
1.0326	2.9851	1400	1.2188
1.013	3.4115	1600	1.2191
1.1103	3.8380	1800	1.2188

Note that the training data volume for the continued pretraining stage is capped at 300MB. When the corresponding century's corpus exceeds this volume, the training data is randomly sampled to fit the volume.
