Personalized Activity Recognition with Deep Triplet Embeddings

15 Jan 2020dmbee/fcn-core

The novel subject triplet loss provides the best performance overall, and all personalized deep embeddings out-perform our baseline personalized engineered feature embedding and an impersonal fully convolutional neural network classifier.

Actions as Moving Points

14 Jan 2020mcg2019/MOC-Detector

The existing action tubelet detectors mainly depend on heuristic anchor box design and placement, which might be computationally expensive and sub-optimal for precise localization of action instances.

Libri-Light: A Benchmark for ASR with Limited or No Supervision

17 Dec 2019facebookresearch/libri-light

Additionally, we provide baseline systems and evaluation metrics working under three settings: (1) the zero resource/unsupervised setting (ABX), (2) the semi-supervised setting (PER, CER) and (3) the distant supervision setting (WER).

BMN: Boundary-Matching Network for Temporal Action Proposal Generation

ICCV 2019 JJBOY/BMN-Boundary-Matching-Network

To address these difficulties, we introduce the Boundary-Matching (BM) mechanism to evaluate confidence scores of densely distributed proposals, which denote a proposal as a matching pair of starting and ending boundaries and combine all densely distributed BM pairs into the BM confidence map.

Dance with Flow: Two-in-One Stream Action Detection

CVPR 2019 jiaozizhao/Two-in-One-ActionDetection

With only half the computation and parameters of the state-of-the-art two-stream methods, our two-in-one stream still achieves impressive results on UCF101-24, UCFSports and J-HMDB.
