人工智能/数据科学比赛汇总 2019.6

06/18 - 06/12 2019 // Host by Biendata // Prize: 40,000元

Note: 科学论文虽然代表了人类对自然最前沿的理解，但大众却很难读懂论文。所以论文发表后，科研机构经常会发布研究新闻稿解释论文中的研究。本次比赛的任务是给定一篇科研新闻，找到这篇新闻描述的论文。

提交数据格式: 新闻数据测试集press_test.csv中的每篇新闻都是在报道论文测试集paper_test.csv中的一篇论文。对于每篇新闻，选手需要从paper_test.csv中选出三篇最相关的论文。参赛者需要在训练集上训练模型，并对新闻和论文的相关行进行预测，最终可以标注 Top 3 的匹配结果。注意：预测出的匹配论文之间存在顺序，按照预测得分，从大到小排序。

本次黑客松任务即挂靠这次会议。在4天的时间里，参赛选手需要通过平台提交预测结果。前三名选手将获得4万元奖金，并被邀请到会议上介绍获奖方法。

转子部件脱落故障预测 (Prognosis of Rotor Parts Fly-off)

http://www.industrial-bigdata...

5月24日 - 7月22日, 2019 // Host by 中国信息通信研究院 // Prize: ￥200,000

Note: 第三届工业大数据创新竞赛

Background: For large rotating machines, due to the high rotating speed and tremendous momentum of the rotor, the centrifugal force may lead to the loose or flying apart of the rotor parts, which brings a great threat to the operation safety of the equipment. This type of fault could lead to high maintenance cost and significant economic loss. The capture of the early symptom of rotor faults is relatively difficult and has become a worldwide challenge in the field of prognostics. It will bring significant safety value and economic benefits if the big data-based methods can detect and predict incipient faults.

赛事简要：大型旋转机组设备高速旋转、动能巨大，转子部件脱落故障给设备安全运行带来巨大威胁。而且这类故障维修成本高、耗时长，早期征兆难以捕捉，是故障预测的世界性难题。如果能通过大数据方法，实现此故障征兆的早期发现和程度预测，将带来显著的安全价值和经济效益。

Visual Domain Adaptation Challenge (VisDA-2019)

http://ai.bu.edu/visda-2019/

April 9 - Sept. 27, 2019 // Host by CodaLab & ICCV 2019 // Prize: NaN

Note: We are pleased to announce the 2019 Visual Domain Adaptation (VisDA2019) Challenge! It is well known that the success of machine learning methods on visual recognition tasks is highly dependent on access to large labeled datasets. Unfortunately, performance often drops significantly when the model is presented with data from a new deployment domain which it did not see in training, a problem known as dataset shift. The VisDA challenge aims to test domain adaptation methods’ ability to transfer source knowledge and adapt it to novel target domains.

This challenge includes two tracks:

Multi-Source Domain Adaptation Challenge

nocaps

https://nocaps.org

Feb 8, 2019 - Apr 26, 2099 // Host by EvalAI // Prize: NaN

Note: Image captioning models have achieved impressive results on datasets containing limited visual concepts and large amounts of paired image-caption training data. However, if these models are to ever function in the wild, a much larger variety of visual concepts must be learned, ideally from less supervision. To encourage the development of image captioning models that can learn visual concepts from alternative data sources, such as object detection datasets, we present the first large-scale benchmark for this task. Dubbed nocaps, for novel object captioning at scale, our benchmark consists of 166,100 human-generated captions describing 15,100 images from the Open Images validation and test sets. The associated training data consists of COCO image-caption pairs, plus Open Images imagelevel labels and object bounding boxes. Since Open Images contains many more classes than COCO, nearly 400 object classes seen in test images have no or very few associated training captions (hence, nocaps). We extend existing novel object captioning models to establish strong baselines for this benchmark and provide analysis to guide future work on this task.
