Deep Learning Recommendation Model for Personalization and Recommendation Systems:
=================================================================================
## 模型结构
```
output:
probability of a click
model: |
/\
/__\
|
_____________________> Op <___________________
/ | \
/\ /\ /\
/__\ /__\ ... /__\
| | |
| Op Op
| ____/__\_____ ____/__\____
| |_Emb_|____|__| ... |_Emb_|__|___|
input:
[ dense features ] [sparse indices] , ..., [sparse indices]
```
More precise definition of model layers:
1) fully connected layers of an mlp
z = f(y)
y = Wx + b
2) embedding lookup (for a list of sparse indices p=[p1,...,pk])
z = Op(e1,...,ek)
obtain vectors e1=E[:,p1], ..., ek=E[:,pk]
3) Operator Op can be one of the following
Sum(e1,...,ek) = e1 + ... + ek
Dot(e1,...,ek) = [e1'e1, ..., e1'ek, ..., ek'e1, ..., ek'ek]
Cat(e1,...,ek) = [e1', ..., ek']'
where ' denotes transpose operation
测试用例执行

基准测试
------------
1) 使用随机生成数据测试
```
./bench/dlrm_s_benchmark.sh
```
2) 使用[Criteo Kaggle Display Advertising Challenge Dataset](https://ailab.criteo.com/ressources/) 数据测试方法.
- 下载并解压数据到/data/kaggle路径下
```
mkdir -p /data/kaggle
tar xvf kaggle-display-advertising-challenge-dataset.tar.gz
```
- 执行测试脚本
```
./bench/dlrm_s_criteo_kaggle.sh [--test-freq=1024]
```
- 可以通过修改脚本中的以下参数来指定测试数据路径
- 首先可以指定训练数据地址 --raw-data-file=<path/train.txt>
- 可以指定预处理后的数据地址 --processed-data-file=<path/*.npz>
训练结果参考如下
<img src="./kaggle_dac_loss_accuracy_plots.png" width="900" height="320">
3) 多节点测试：代码支持分布式训练，目前支持gloo/nccl/mpi.
```
# 单节点4颗DCU测试，使用nccl通信，测试数据使用随机生成数据:
python -m torch.distributed.launch --nproc_per_node=8 dlrm_s_pytorch.py --arch-embedding-size="80000-80000-80000-80000-80000-80000-80000-80000" --arch-sparse-feature-size=64 --arch-mlp-bot="128-128-128-128" --arch-mlp-top="512-512-512-256-1" --max-ind-range=40000000
--data-generation=random --loss-function=bce --round-targets=True --learning-rate=1.0 --mini-batch-size=2048 --print-freq=2 --print-time --test-freq=2 --test-mini-batch-size=2048 --memory-map --use-gpu --num-batches=100 --dist-backend=nccl
# 多节点的情况可以添加如下参数:
--nnodes=2 --node_rank=0 --master_addr="192.168.1.1" --master_port=1234
```
保存、加载模型参数
-------------------------------
* --save-model=<path/model.pt> ： 保存模型地址、名称
* --load-model=<path/model.pt> ： 加载模型
