CaffeOnSpark架构如图2所示,Spark on YARN加载了一些执行器(用户可以指定Spark执行器的个数(–num-executors<# of EXECUTORS>),以及为每个执行器分配的GPU的个数(-devices <# of GPUs PER EXECUTOR>))。每个执行器分配到一个基于HDFS的训练数据分区,然后开启多个基于Caffe的训练线程。每个训练线程由一个特定的GPU...

1、匹配(matching):利用协同过滤等方法,生成与用户相关的候选广告列表。 2、排序(ranking):为每个候选广告,预测CTR值,选择排序靠前的广告。 每天有数亿计的用户访问电商网站,行为比较丰富的用户,兴趣也是多样化的。 以一个年轻母亲为例,浏览过的商品包括毛外套、T恤、耳环、提包、皮包、儿童外套等。这些数据暗示了...
今年2月23日,清华大学计算机系崔鹏副教授与斯坦福大学Susan Athey(美国科学院院士,因果领域国际权威)合作,在世界顶级期刊Nature Machine Intelligence(影响因子IF=15.51,2020)上发表了一篇题为“Stable Learning Establishes Some Common Ground Between Causal Inference and Machine Learning”(稳定学习:建立因果推理和机器学...
并且实现了很多常用的 RecSys 模型,例如:Deep Interest Network (DIN), NCF, Wide and Deep Learning (WDL), Deep Cross Network (DCN), DeepFM,和 Deep Learning Recommendation Model (DLRM). HugeCTR 可以参考 B 站的这两个视频: Merlin HugeCTR:GPU 加速的推荐系统框架 HugeCTR 分级参数服务器如何加速推理 ...
(Fig.3Ctop). The narrow spread of the values obtained with DeepRank, illustrated by the 25–75% quantile interval, indicates that DeepRank is rather consistent in its ranking of different cases, while HADDOCK presents poor performance for some cases. This difference might be explained by the ...
Furthermore, fast deep learning can be achieved by restricting the size of network. With the help of GPU, the time complexity of the network training is released to a large extent. Under the framework of particle filter, the proposed method combined the deep learning extractor with an SVM ...
“We are seeing that there is an insatiable appetite for GPU computing for deep learning workloads,” explains Ram, which explains why HPE went back to the drawing board and came up with a better design that could provide the power and cooling to support accelerators that run hotter and provi...
使用GaLore在本地GPU进行高效的LLM调优 训练大型语言模型(llm),即使是那些“只有”70亿个参数的模型,也是一项计算密集型的任务。这种水平的训练需要的资源超出了大多数个人爱好者的能力范围。为了弥补这一差距,出现了低秩适应(LoRA)等参数高效方法,可以在消费级gpu上对大量模型进行微调。
query user, several thousands of items are sent along in a single request for item re-ranking. Compared to an 80-thread CPU inference, a Tesla V100 32-GB GPU offers up to 20x improvement in throughput. You can see that the GPU throughput starts to saturate at around a batch size of ...
