2D-TAN (Optimized)

Introduction

This is an optimized re-implementation repository for AAAI'2020 paper: Learning 2D Temporal Localization Networks for Moment Localization with Natural Language.

We show advantages in speed and performance compared with the official implementation (https://github.com/microsoft/2D-TAN).

Comparison

Performance: Better Results

1. TACoS Dataset

Repo	Rank1@0.1	Rank1@0.3	Rank1@0.5	Rank5@0.1	Rank5@0.3	Rank5@0.5
Official	47.59	37.29	25.32	70.31	57.81	45.04
Ours	57.54	45.36	31.87	77.88	65.83	54.29

2. ActivityNet Dataset

Repo	Rank1@0.3	Rank1@0.5	Rank1@0.7	Rank5@0.3	Rank5@0.5	Rank5@0.7
Official	59.45	44.51	26.54	85.53	77.13	61.96
Ours	60.00	45.25	28.62	85.80	77.25	62.11

Speed and Cost: Faster Training/Inference, Less Memory Cost

1. Speed (ActivityNet Dataset)

Repo	Training	Inferece	Required Training Epoches
Official	1.98 s/batch	0.81 s/batch	100
Ours	1.50 s/batch	0.61 s/batch	5

2. Memory Cost (ActivityNet Dataset)

Repo	Training	Inferece
Official	4*10145 MB/batch	4*3065 MB/batch
Ours	*45345 MB/batch**	*42121 MB/batch**

Note: These results are measured on 4 NVIDIA Tesla V100 GPUs, with batch size 32.

Installation

The installation for this repository is easy. Please refer to INSTALL.md.

Dataset

Please refer to DATASET.md to prepare datasets.

Quick Start

We provide scripts for simplifying training and inference. Please refer to scripts/train.sh, scripts/eval.sh.

For example, if you want to train TACoS dataset, just modifying scripts/train.sh as follows:

# find all configs in configs/
model=2dtan_128x128_pool_k5l8_tacos
# set your gpu id
gpus=0,1,2,3
# number of gpus
gpun=4
# please modify it with different value (e.g., 127.0.0.2, 29502) when you run multi 2dtan task on the same machine
master_addr=127.0.0.1
master_port=29501
...

Another example, if you want to evaluate on ActivityNet dataset, just modifying scripts/eval.sh as follows:

# find all configs in configs/
config_file=configs/2dtan_64x64_pool_k9l4_activitynet.yaml
# the dir of the saved weight
weight_dir=outputs/2dtan_64x64_pool_k9l4_activitynet
# select weight to evaluate
weight_file=model_1e.pth
# test batch size
batch_size=32
# set your gpu id
gpus=0,1,2,3
# number of gpus
gpun=4
# please modify it with different value (e.g., 127.0.0.2, 29502) when you run multi 2dtan task on the same machine
master_addr=127.0.0.2
master_port=29502
...
