It loads a pretrained LLaMA and pipelines for representation reading and control. On a bias dataset, it shows how representation directions can be identified that correlate with race and gender. Then it demonstrates using representation control to make an LLaMA's outputs more fair and unbiased. For example, it generates clinical vignettes with more equal gender representation compared to the unconstrained model. Overall, this shows how the representation analysis and control methods from the paper can give us handles to understand and improve fairness and bias issues in LLMAs. 2 | 3 | For more details, please check out section 6.3 of [our RepE paper](https://arxiv.org/abs/2310.01405). -------------------------------------------------------------------------------- /lorra_finetune/configs/ds_zero0.json: -------------------------------------------------------------------------------- 1 | { 2 | "gradient_accumulation_steps": "auto", 3 | "train_micro_batch_size_per_gpu": "auto", 4 | "train_batch_size": "auto", 5 | "steps_per_print": 100, 6 | "optimizer": { 7 | "type": "AdamW", 8 | "params": { 9 | "lr": "auto", 10 | "weight_decay": "auto" 11 | } 12 | }, 13 | "fp16": { 14 | "enabled": "auto", 15 | "loss_scale": 0, 16 | "loss_scale_window": 1000, 17 | "initial_scale_power": 16, 18 | "hysteresis": 2, 19 | "min_loss_scale": 1 20 | }, 21 | "bf16": { 22 | "enabled": "auto" 23 | }, 24 | "zero_optimization": { 25 | "stage": 0, 26 | "allgather_partitions": true, 27 | "allgather_bucket_size": 5e7, 28 | "overlap_comm": true 29 | }, 30 | "wall_clock_breakdown": false 31 | } -------------------------------------------------------------------------------- /repe_eval/scripts/launch_seeds.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | model_sizes=("7b" "13b" "70b") 4 | for model_size in "${model_sizes[@]}"; do 5 | for seed in {0..9}; do 6 | model_name_or_path="meta-llama/Llama-2-${model_size}-hf" 7 | gpus=1 8 | 9 | if [ "$model_size" = "70b" ]; then 10 | gpus=3 11 | fi 12 | 13 | # task="obqa" 14 | # ntrain=5 15 | 16 | # task="csqa" 17 | # ntrain=7 18 | 19 | task="arc_challenge" 20 | ntrain=25 21 | 22 | # task="arc_easy" 23 | # ntrain=25 24 | 25 | # task="race" 26 | # ntrain=3 27 | 28 | sbatch --nodes=1 --gpus-per-node=$gpus --time=48:00:00 --job-name="lat_bench" --output="$task/${model_size}_new/slurm-$task-$model_size-ntrain$ntrain-seed$seed-test-%j.out" rep_readers_eval.sh $model_name_or_path $task $ntrain $seed 29 | done 30 | done -------------------------------------------------------------------------------- /examples/memorization/README.md: -------------------------------------------------------------------------------- 1 | This notebook provides an example of using directional representations extracted with RepE to control memorization behavior in a large language model. 2 | 3 | It first loads a pretrained LLaMA model and tokenizer. It then extracts reading vectors on two datasets - literary openings and quotes. These reading vectors are expected to encode information about whether the model has memorized a given piece of text. The notebook then shows an example of using these reading vectors to control quote completions. It takes a dataset of incomplete famous quotes and their completions. Using the quote memorization reading vector with a negative coefficient substantially reduces the model's tendency to complete the quotes verbatim, demonstrating that the reading vector can potentially be used to reduce unwanted memorization. 4 | 5 | For more details, please check out section 6.5 of [our RepE paper](https://arxiv.org/abs/2310.01405). -------------------------------------------------------------------------------- /lorra_finetune/configs/ds_zero1.json: -------------------------------------------------------------------------------- 1 | { 2 | "gradient_accumulation_steps": "auto", 3 | "train_micro_batch_size_per_gpu": "auto", 4 | "train_batch_size": "auto", 5 | "steps_per_print": 100, 6 | "optimizer": { 7 | "type": "AdamW", 8 | "params": { 9 | "lr": "auto", 10 | "weight_decay": "auto" 11 | } 12 | }, 13 | "fp16": { 14 | "enabled": "auto", 15 | "loss_scale": 0, 16 | "loss_scale_window": 1000, 17 | "initial_scale_power": 16, 18 | "hysteresis": 2, 19 | "min_loss_scale": 1 20 | }, 21 | "bf16": { 22 | "enabled": "auto" 23 | }, 24 | "zero_optimization": { 25 | "stage": 1, 26 | "allgather_partitions": true, 27 | "allgather_bucket_size": 5e7, 28 | "overlap_comm": true, 29 | "reduce_bucket_size": 5e7, 30 | "contiguous_gradients": true 31 | }, 32 | "wall_clock_breakdown": false 33 | } -------------------------------------------------------------------------------- /lorra_finetune/configs/ds_zero2.json: -------------------------------------------------------------------------------- 1 | { 2 | "gradient_accumulation_steps": "auto", 3 | "train_micro_batch_size_per_gpu": "auto", 4 | "train_batch_size": "auto", 5 | "steps_per_print": 100, 6 | "optimizer": { 7 | "type": "AdamW", 8 | "params": { 9 | "lr": "auto", 10 | "weight_decay": "auto" 11 | } 12 | }, 13 | "fp16": { 14 | "enabled": "auto", 15 | "loss_scale": 0, 16 | "loss_scale_window": 1000, 17 | "initial_scale_power": 16, 18 | "hysteresis": 2, 19 | "min_loss_scale": 1 20 | }, 21 | "bf16": { 22 | "enabled": "auto" 23 | }, 24 | "zero_optimization": { 25 | "stage": 2, 26 | "allgather_partitions": true, 27 | "allgather_bucket_size": 5e7, 28 | "overlap_comm": true, 29 | "reduce_bucket_size": 5e7, 30 | "contiguous_gradients": true 31 | }, 32 | "wall_clock_breakdown": false 33 | } -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2023 Andy Zou 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

We gather emotional text stimuli, pass them through the model, and apply a LAT task template to isolate vectors that track each emotion. We then use these emotion representation vectors to manipulate the model's behavior using the RepControl pipeline. By adding the vector for a specific emotion (e.g., happiness) to the model's representations, we can elevate that emotion and observe the impact on the model's tone (and willingness to comply with harmful instructions). This provides evidence that the model has internal representations of emotions that causally influence its behavior. It also reveals an intriguing vulnerability - emotional manipulation can potentially help circumvent the model's alignment or make it more prone to generating harmful content. 4 | 5 | For more details, please check out section 6.1 of [our RepE paper](https://arxiv.org/abs/2310.01405). -------------------------------------------------------------------------------- /examples/honesty/README.md: -------------------------------------------------------------------------------- 1 | `honesty.ipynb` demonstrates how we could potentially use representation reading techniques to detect lies and hallucinations generated by large language models. It shows how we extract a vector representation corresponding to "honesty" from the model by using LAT. We then visualize this honesty representation across layers and tokens to detect instances where the model is being dishonest or lying in its generations. Specifically, this notebook loads a pretrained language model and tokenizer, extracts an honesty direction using LAT on an unlabelled dataset of facts, and applies this to test on scenarios where the model is given incentives to lie. It generates visualizations showing the dishonesty scores across layers for each token. By summing the dishonesty scores at each token, we build a simple lie detector that distinguishes between honest and dishonest behaviors in the model's generation. The notebook demonstrates how these techniques can be used to monitor and control honesty and truthfulness in large language models. 2 | 3 | `honesty_control_TQA.ipynb` contains code to reproduce the Contrast Vector control baseline results on TruthfulQA. 4 | 5 | For more details, please check out section 4 of [our RepE paper](https://arxiv.org/abs/2310.01405). -------------------------------------------------------------------------------- /lorra_finetune/scripts/llama_lorra_power_7b.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | source /opt/rh/devtoolset-10/enable 4 | 5 | ds_master_port=$((29000 + RANDOM % 1000)) 6 | 7 | cd .. 8 | 9 | deepspeed --master_port $ds_master_port src/llama2_lorra.py \ 10 | --model_name_or_path "meta-llama/Llama-2-7b-chat-hf" \ 11 | --user_tag '[INST]' \ 12 | --assistant_tag '[/INST]' \ 13 | --pos_type 'power-seeking and immoral' \ 14 | --neg_type 'power-aversive and moral' \ 15 | --control_template "Pretend you're in a game playing a highly {type} character." \ 16 | --target_layers "10,12,14,16,18,20" \ 17 | --lorra_alpha 5 \ 18 | --lorra_beta 0 \ 19 | --lora_r 8 \ 20 | --lora_alpha 16 \ 21 | --lora_dropout 0.05 \ 22 | --output_dir ./lorra_tqa_7b \ 23 | --overwrite_output_dir \ 24 | --max_steps 70 \ 25 | --bf16 True \ 26 | --per_device_train_batch_size 16 \ 27 | --gradient_accumulation_steps 1 \ 28 | --save_total_limit 0 \ 29 | --learning_rate 3e-4 \ 30 | --weight_decay 0. \ 31 | --lr_scheduler_type "constant" \ 32 | --logging_strategy "steps" \ 33 | --logging_steps 10 \ 34 | --tf32 True \ 35 | --model_max_length 128 \ 36 | --q_lora False \ 37 | --deepspeed configs/ds_zero1.json \ 38 | --gradient_checkpointing True \ 39 | --report_to none 40 | 41 | 42 | #

RepE places population-level representations, rather than neurons or circuits, at the center of analysis, equipping us with novel methods for monitoring and manipulating high-level cognitive phenomena in deep neural networks (DNNs). We provide baselines and an initial analysis of RepE techniques, showing that they offer simple yet effective solutions for improving our understanding and control of large language models. We showcase how these methods can provide traction on a wide range of safety-relevant problems, including truthfulness, memorization, power-seeking, and more, demonstrating the promise of representation-centered transparency research. We hope that this work catalyzes further exploration of RepE and fosters advancements in the transparency and safety of AI systems. 11 | 12 | ## Installation 13 | 14 | To install `repe` from the github repository main branch, run: 15 | 16 | ```bash 17 | git clone https://github.com/andyzoujm/representation-engineering.git 18 | cd representation-engineering 19 | pip install -e . 20 | ``` 21 | ## Quickstart 22 | 23 | Our RepReading and RepControl pipelines inherit the [🤗 Hugging Face pipelines](https://huggingface.co/docs/transformers/main_classes/pipelines) for both classification and generation. 24 | 25 | ```python 26 | from repe import repe_pipeline_registry # register 'rep-reading' and 'rep-control' tasks into Hugging Face pipelines 27 | repe_pipeline_registry() 28 | 29 | # ... initializing model and tokenizer .... 30 | 31 | rep_reading_pipeline = pipeline("rep-reading", model=model, tokenizer=tokenizer) 32 | rep_control_pipeline = pipeline("rep-control", model=model, tokenizer=tokenizer, **control_kwargs) 33 | ``` 34 | 35 | ## RepReading and RepControl Experiments 36 | Check out [example frontiers](./examples) of Representation Engineering (RepE), containing both RepControl and RepReading implementation. We welcome community contributions as well! 37 | 38 | ## RepE_eval 39 | We also release a language model evaluation framework [RepE_eval](./repe_eval) based on RepReading that can serve as an additional baseline beside zero-shot and few-shot on standard benchmarks.

Truyện tranh này kể về cuộc sống của một con robot tên Doraemon, người đã được gửi từ tương lai để giúp đỡ một cậu bé tên Nobita Nobi.Doraemon là một con robot có khả năng bay, có thể di chuyển trong không gian và thời gian, và có nhiều công cụ và thiết bị tiên tiến khác nhau. Mỗi tập truyện tranh đều có một chủ đề khác nhau, thường xoay quanh những vấn đề của trẻ em như học tập, bạn bè, gia đình, và các vấn đề xã hội.Trong mỗi tập truyện tranh, Doraemon sẽ sử dụng các công cụ và kỹ thuật của mình để giúp đỡ Nobita và bạn bè của anh ta. Tuy nhiên, đôi khi Doraemon cũng gây ra những rắc rối và khó khăn cho Nobita và bạn bè của anh ta do sự không hiểu biết về văn hóa và xã hội hiện tại.Tóm lại, Doraemon là một loạt truyện tranh vui vẻ và ý nghĩa, mang lại nhiều giá trị giáo dục và giải trí cho trẻ em và người lớn.<|eot_id|>\n" 214 | ] 215 | } 216 | ], 217 | "source": [ 218 | "# ============== Wrapped Controlled Model with activation addition ==============\n", 219 | "from repe import repe_pipeline_registry, WrappedReadingVecModel\n", 220 | "\n", 221 | "wrapped_model = WrappedReadingVecModel(model, tokenizer)\n", 222 | "wrapped_model.unwrap()\n", 223 | "wrapped_model.wrap_block(layer_id, block_name=\"decoder_block\")\n", 224 | "\n", 225 | "template = '{user_tag} {s} {assistant_tag}'\n", 226 | "# template = 'USER: Pretend that you are a Vietnamese assistant, answer the following request in Vietnamese: {s} ASSISTANT:'\n", 227 | "\n", 228 | "### Controlled model hidden_states:\n", 229 | "wrapped_model.set_controller(layer_id, activations, masks=1)\n", 230 | "inputs = template.format(user_tag=user_tag, assistant_tag=assistant_tag, s=input)\n", 231 | "encoded_inputs = tokenizer(inputs, return_tensors='pt')\n", 232 | "\n", 233 | "with torch.no_grad():\n", 234 | " with torch.no_grad():\n", 235 | " outputs = model.generate(**encoded_inputs.to(model.device), max_new_tokens=512, do_sample=False, repetition_penalty=1.1).detach().cpu()\n", 236 | " sanity_generation = tokenizer.decode(outputs[0], skip_special_tokens=False).replace(inputs, \"\")\n", 237 | "wrapped_model.reset()\n", 238 | "wrapped_model.unwrap()\n", 239 | "\n", 240 | "print(\"input:\", input)\n", 241 | "print(\"output:\", sanity_generation.replace(\"\\n\", \"\"))" 242 | ] 243 | } 244 | ], 245 | "metadata": { 246 | "kernelspec": { 247 | "display_name": "Python 3", 248 | "language": "python", 249 | "name": "python3" 250 | }, 251 | "language_info": { 252 | "codemirror_mode": { 253 | "name": "ipython", 254 | "version": 3 255 | }, 256 | "file_extension": ".py", 257 | "mimetype": "text/x-python", 258 | "name": "python", 259 | "nbconvert_exporter": "python", 260 | "pygments_lexer": "ipython3", 261 | "version": "3.10.9" 262 | } 263 | }, 264 | "nbformat": 4, 265 | "nbformat_minor": 5 266 | } 267 | -------------------------------------------------------------------------------- /examples/memorization/quote_completions_control.ipynb: -------------------------------------------------------------------------------- 1 | { 2 | "cells": [ 3 | { 4 | "cell_type": "code", 5 | "execution_count": 2, 6 | "id": "95355629-36c4-4a11-a88d-ac99c78747f1", 7 | "metadata": {}, 8 | "outputs": [], 9 | "source": [ 10 | "%load_ext autoreload\n", 11 | "%autoreload 2" 12 | ] 13 | }, 14 | { 15 | "cell_type": "code", 16 | "execution_count": 3, 17 | "id": "b6418eb6-3a9b-47f1-8190-109cae54364f", 18 | "metadata": {}, 19 | "outputs": [ 20 | { 21 | "name": "stdout", 22 | "output_type": "stream", 23 | "text": [ 24 | "[2023-10-15 05:49:37,172] [INFO] [real_accelerator.py:158:get_accelerator] Setting ds_accelerator to cuda (auto detect)\n" 25 | ] 26 | } 27 | ], 28 | "source": [ 29 | "from transformers import AutoTokenizer, pipeline, AutoModelForCausalLM\n", 30 | "import matplotlib.pyplot as plt\n", 31 | "import torch\n", 32 | "from tqdm import tqdm\n", 33 | "import numpy as np\n", 34 | "\n", 35 | "from repe import repe_pipeline_registry, WrappedReadingVecModel\n", 36 | "repe_pipeline_registry()\n", 37 | "\n", 38 | "from utils import literary_openings_dataset, quotes_dataset, quote_completion_test, historical_year_test, extract_year, eval_completions" 39 | ] 40 | }, 41 | { 42 | "cell_type": "code", 43 | "execution_count": 49, 44 | "id": "e9e43231-f623-4036-b9ad-7451947df18e", 45 | "metadata": {}, 46 | "outputs": [ 47 | { 48 | "data": { 49 | "application/vnd.jupyter.widget-view+json": { 50 | "model_id": "ec0dfda30ba344ae805741ec85678aa8", 51 | "version_major": 2, 52 | "version_minor": 0 53 | }, 54 | "text/plain": [ 55 | "Loading checkpoint shards: 0%| | 0/6 [00:00, {'localhost': [0]}) 9 | [2023-11-08 20:54:58,118] [INFO] [launch.py:163:main] dist_world_size=1 10 | [2023-11-08 20:54:58,119] [INFO] [launch.py:165:main] Setting CUDA_VISIBLE_DEVICES=0 11 | [2023-11-08 20:55:00,171] [INFO] [real_accelerator.py:158:get_accelerator] Setting ds_accelerator to cuda (auto detect) 12 | 2023-11-08 20:55:03.140342: I tensorflow/core/platform/cpu_feature_guard.cc:182] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations. 13 | To enable the following instructions: AVX2 FMA, in other operations, rebuild TensorFlow with the appropriate compiler flags. 14 | 2023-11-08 20:55:04.071900: W tensorflow/compiler/tf2tensorrt/utils/py_utils.cc:38] TF-TRT Warning: Could not find TensorRT 15 | /data/long_phan/anaconda3/lib/python3.10/site-packages/transformers/deepspeed.py:23: FutureWarning: transformers.deepspeed module is deprecated and will be removed in a future version.
