#TagSpace: Semantic Embeddings from Hashtags

Empirical Methods in Natural Language Processing

We describe a convolutional neural network that learns feature representations for short textual posts using hashtags as a supervised signal. The proposed approach is trained on up to 5.5 billion words predicting 100,000 possible hashtags.

Optimal Crowd-Powered Rating and Filtering Algorithms

VLDB 2014

We focus on crowd-powered filtering, i.e., filtering a large set of items using humans. Filtering is one of the most commonly used building blocks in crowdsourcing applications and systems. While solu…

Streamed Approximate Counting of Distinct Elements

ACM Conference on Knowledge Discovery and Data Mining (KDD)

Counting the number of distinct elements in a large dataset is a common task in web applications and databases. This problem is difficult in limited memory settings where storing a large hash table ta…

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…

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…

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.

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…
