MultiPLY is a <strong>multisensory embodied</strong> large language model that could actively interact with the objects in the 3D environment and dynamically collect their multisensory information. It could incorporate multisensory interactive data, including visual, audio, tactile, and thermal information into large language models, thereby establishing the correlation among words, actions, and perceptions.

Method

<p align="center"> <img src="figs/method.png" alt="Logo" width="80%"> </p>

We first encode the scene as an abstracted object-centric representation, while multisensory details of objects can only be unveiled when the agent executes an action and interacts with them. We devise a set of action tokens denoting the actions of agents to interact with the environment. The interaction results are appended back to the LLM via state tokens

Training

We use FSDP training. It might differ on different clusters. An example on the trained cluster is:

RANDOM=$$
DIV=1000
OFFSET=24000
MASTER_PORT=$(($RANDOM%$DIV+$OFFSET))
export OMP_NUM_THREADS=1
export TOKENIZERS_PARALLELISM=true
NODE_RANK=${SLURM_PROCID}

SLURM=${SLURM_NODELIST:0:3}
ip=${SLURM}${SLURM_NODELIST:4:2}

# run the training script
NUM_GPUS_PER_NODE=${1:-8}
echo $NUM_GPUS_PER_NODE

NUM_NODES=${2:-1}
CMD="torchrun --nnodes=$NUM_NODES --nproc_per_node=$NUM_GPUS_PER_NODE --master_addr=$ip --node_rank=$NODE_RANK"

$CMD \
fsdp_train.py --folder retrieval_attention3 --num_epochs=1000
