Proxy-based Loss有加速收敛,且可以较好地缓解noise labels 和 outliers负面影响的优点。 使用普通的Random Sampler即可满足需求,但是Batch size设置地大一些性能会有提升。 Figure 1. Comparison between Proxy-NCA Loss and Proxy Anchor Loss. 具体地,如图1(e)所示,Proxy-Anchor Loss为每一个类别赋予了一个proxy(...
Overall, the Proxy-Anchor loss performs better than the other losses in terms of accuracy, recall, data separation, and image retrieval. 展开 关键词: Measurement Training Image retrieval Image representation Data models Task analysis Faces 会议名称: 2020 International Conference on Advanced Computer ...
标准的代理方法是softmax CE loss(即softmax交叉熵损失),其中代理用于表示类别。对比方法和基于代理的方法之间的主要区别在于关系构建。如图2所示,对比损失主要关注探索丰富的样本对之间的关系,而基于代理的损失使用代理来表示子训练集,实现了安全且快速的收敛,但遗漏了一些语义关系。这激发了我们设计一个基于代理的损失...
The first is the proxy-based replay manner, which is to replay by using the proxy-based loss and softmax classifier. As shown in Fig- ure 1(a), it calculates similarities between each anchor with 24246 all proxies belonging to C classes. A proxy can b...

Simulation results carried out in ns-2 show that TCP and TFRC can not fully utilize the WCDMA bearer at 5% packet loss rate over the shared public Internet link. Smooth playout of a typical 64 kbps video stream would require high initial buffering delays (>10 seconds) and large receiver ...
Whether deployed in the cloud or on-premises, CASBs provide visibility into the use of cloud applications, control access to cloud-based services and data, help meet compliance regulations, prevent data loss, detect and remediate threats with UEBA technology, and more. With the help of a CASB ...
High dynamicity affects the design and implementation of distributed applications by significantly increasing their complexity, to consider not only routing and node configuration issues, but also the possible mobility of software components and the loss of direct connectivity during service provisioning. ...
We also demonstrate how fairness between flows and response to loss is improved, and that queueing and hence network latency is reduced. We discuss how TCP enhancing proxies could be transparently deployed, and conclude that installing such a proxy into GPRS network would be of significant benefit...
We propose a fast handover mechanism which introduces the idea of hierarchical network architecture into PMIPv6, to solve the problem that the MN encountered during handover in PMIPv6 domain; moreover, we introduce an additional buffering scheme to reduce packet loss and solve packet ordering ...
