Exploiting Counter-Examples for Active Learning with Partial labels

no code implementations14 Jul 2023 Fei Zhang, Yunjie Ye, Lei Feng, Zhongwen Rao, Jieming Zhu, Marcus Kalander, Chen Gong, Jianye Hao, Bo Han

In this setting, an oracle annotates the query samples with partial labels, relaxing the oracle from the demanding accurate labeling process.

Out-of-distribution Detection with Implicit Outlier Transformation

1 code implementation9 Mar 2023 Qizhou Wang, Junjie Ye, Feng Liu, Quanyu Dai, Marcus Kalander, Tongliang Liu, Jianye Hao, Bo Han

It leads to a min-max learning scheme -- searching to synthesize OOD data that leads to worst judgments and learning from such OOD data for uniform performance in OOD detection.

Exploit CAM by itself: Complementary Learning System for Weakly Supervised Semantic Segmentation

no code implementations4 Mar 2023 Jiren Mai, Fei Zhang, Junjie Ye, Marcus Kalander, Xian Zhang, Wankou Yang, Tongliang Liu, Bo Han

Motivated by this simple but effective learning pattern, we propose a General-Specific Learning Mechanism (GSLM) to explicitly drive a coarse-grained CAM to a fine-grained pseudo mask.

RiskLoc: Localization of Multi-dimensional Root Causes by Weighted Risk

no code implementations20 May 2022 Marcus Kalander

In this work, we consider the problem of identifying the root cause set that best explains an anomaly in multi-dimensional time series with categorical attributes.

Discrete-time Temporal Network Embedding via Implicit Hierarchical Learning in Hyperbolic Space

1 code implementation8 Jul 2021 Menglin Yang, Min Zhou, Marcus Kalander, Zengfeng Huang, Irwin King

To explore these properties of a complex temporal network, we propose a hyperbolic temporal graph network (HTGN) that fully takes advantage of the exponential capacity and hierarchical awareness of hyperbolic geometry.

An Ensemble Noise-Robust K-fold Cross-Validation Selection Method for Noisy Labels

no code implementations6 Jul 2021 Yong Wen, Marcus Kalander, Chanfei Su, Lujia Pan

E-NKCVS is empirically shown to be highly tolerant to considerable proportions of label noise and has a consistent improvement over state-of-the-art methods.

An Influence-based Approach for Root Cause Alarm Discovery in Telecom Networks

1 code implementation7 May 2021 Keli Zhang, Marcus Kalander, Min Zhou, Xi Zhang, Junjian Ye

Alarm root cause analysis is a significant component in the day-to-day telecommunication network maintenance, and it is critical for efficient and accurate fault localization and failure recovery.

Spatio-Temporal Hybrid Graph Convolutional Network for Traffic Forecasting in Telecommunication Networks

no code implementations17 Sep 2020 Marcus Kalander, Min Zhou, Chengzhi Zhang, Hanling Yi, Lujia Pan

We conduct extensive experiments on real-world traffic datasets collected from telecommunication networks.
