Practical Lessons from Predicting Clicks on Ads at Facebook

International Workshop on Data Mining for Online Advertising (ADKDD)

Online advertising allows advertisers to only bid and pay for measurable user responses, such as clicks on ads. As a consequence, click prediction systems are central to most online advertising system…

A Hitchhiker’s Guide to Fast and Efficient Data Reconstruction in Erasure-coded Data Centers

ACM Conference on Applications, Technologies, Architectures, and Protocols for Computer Communications (SIGCOMM)

Erasure codes such as Reed-Solomon (RS) codes are being extensively deployed in data centers since they offer significantly higher reliability than data replication methods at much lower storage overheads. These codes however mandate much higher resources with respect to network bandwidth and disk IO during reconstruction of data that is missing or otherwise unavailable.

Fastpass: A Centralized “Zero-Queue” Datacenter Network

ACM Conference on Applications, Technologies, Architectures, and Protocols for Computer Communications (SIGCOMM)

Current datacenter networks inherit the principles that went into the design of the Internet, where packet transmission and path selection decisions are distributed among the endpoints and routers. In…

DeepFace: Closing the Gap to Human-Level Performance in Face Verification

Conference on Computer Vision and Pattern Recognition (CVPR)

In modern face recognition, the conventional pipeline consists of four stages: detect => align => represent => classify. We revisit both the alignment step and the representation step by employing exp…

PANDA: Pose Aligned Networks for Deep Attribute Modeling

Conference on Computer Vision and Pattern Recognition (CVPR)

We propose a method for inferring human attributes (such as gender, hair style, clothes style, expression, action) from images of people under large variation of viewpoint, pose, appearance, articulat…

Adaptive HTER Estimation for Document-Specific MT Post-Editing

Annual Conference of Association of Computational Linguistics (ACL)

We present an adaptive translation quality estimation (QE) method to predict the human targeted translation error rate (HTER) for a document-specific machine translation model. We first introduce fea…

vCacheShare: Automated Server Flash Cache Space Management in a Virtualization Environment

USENIX Annual Technical Conference (ATC)

Server Flash Cache (SFC) is being increasingly adopted in virtualization environments for IO acceleration. Deciding the optimal SFC allocation among VMs or VM disks is a major pain-point, dominantly handled manually by administrators.
