　　 目录 　　在序列标注模型中使用位置注意力进行抽取实体与重叠关系的联合抽取 　　将混合CTC/Attention方法嵌入到Transformer结构中实现在线端到端的流式语音识别架构 　　基于人工反向修正数据的差异学习 　　利用一种基于多属性邻近度的方法从可比较的新闻语料库中挖掘事件 　　Skip-Thought向量 　　 在序列标注模型中使用位置注意力进行抽取实体与重叠关系的联合抽取 　　论文名称：Joint extraction of entities and overlapping relations using position-attentive sequence labeling 　　作者：Dai Dai / Xinyan Xiao / Yajuan Lyu / Shan Dou / Qiaoqiao She / Haifeng Wang 　　发表时间：2019/7/17 　　论文链接：https://aaai.org/ojs/index.php/AAAI/article/view/4591 　　本文设计了一种基于位置信息和上下文信息的注意力机制，同时将一个关系抽取任务拆成了n(n为句子的长度)个序列标注子任务，一个阶段即可将实体、关系等信息抽取出来。 　　本文发表时在两个数据集上达到了SOTA，并且对于跨度长的关系、重叠关系表现尤其好。 　

向量索引算法HNSW和NSG的比较

随着机器学习、深度神经网络的不断发展，数据的向量化无处不在。而针对海量向量数据的搜索，无论是工业界还是学术界都做了大量的研究。本文主要讲解两个基于近邻图的向量搜索算法，并比较其适用场景。 这里不得不先提一个学术上的对应名词 Approximate Nearest Neighbor Search (ANNS)，近似的最近邻搜索。之所以近似是由于精确的近邻搜索太过困难，研究随之转向了在精确性和搜索时间做取舍。由于精确的向量搜索在海量数据的场景下搜索时间过长，所以目前的常见做法，是在向量上建立近似搜索索引。 这里先介绍一下现在常用的索引类型以及它们的局限性。首先是基于树的算法，这里举例较为经典的 KD-tree。这种索引类型在向量维度稍大一些的情况下 (d>10)，索引性能会急剧下降甚至不如暴力搜索。再说说基于 LSH (locality-sensitive hashing) 的索引，如果想要取得高召回率，LSH算法必须要建立大量的Hash表，这会使得索引大小膨胀数倍。不仅如此，树和LSH都属于空间切分类算法，此类算法有一个无法避免的缺陷，即为了提高搜索精度，只能增大搜索空间。图1-A描述了基于树的切分搜索，每个虚线分割出的区域是一个子树，如果搜索向量在子树的边缘时，算法需要搜索多个子树来获取结果。图1-B描述了基于 Hash 的切分搜索，虚线描述了每个独立的hash表

Extracting Distance from FacetWP Proximity Function to Display in Wordpress Template

由 空扰寡人 提交于 2020-02-28 18:52:46
问题 I am quite new to Wordpress & Php coding in general, I have a relatively simple theme that I have been working with that contains a custom post type that stores latitude and longitude. Each post is a listing a hotel listing within a directory. The theme I am using also integrates with FacetWP the faceting plugin for WordPress. It is possible for the user to search the site by typing a location of locating themselves, this happens using Googles Mapping functionality. When the search is

How can i get exact distance in feets from the beacon, using roximity sdk?

由 两盒软妹~` 提交于 2020-02-06 03:56:04
问题 I am using Roximity SDK and it gives beacons range update but only with three points Far, Near and Immediate, while i want to get their distance in feets, any idea how can i get this ? Here's the code i have used according to roximity SDK docs. private void createBroadcastRecievers(){ IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(ROXConsts.MESSAGE_FIRED); intentFilter.addAction(ROXConsts.BEACON_RANGE_UPDATE); intentFilter.addAction(ROXConsts.WEBHOOK_POSTED);

Proximity Alerts not working after phone reboot

由 蹲街弑〆低调 提交于 2020-01-05 09:25:46
问题 I am using proximity alerts in one of my applications, however it seems that whenever I reset my phone (via battery pull) or just in general, the proximity alerts are no longer active. The only way they work once again is if I uncheck and recheck the checkbox (which removes, then re-adds the proximity alert) Any idea's or reason? 回答1: You must reset the alerts. The Android OS does not persist your alerts when rebooting, that's up to your app. Create a BroadcastReceiver (I called mine

Prevent the iOS proximity sensor from turning the screen black

由 旧街凉风 提交于 2020-01-03 17:15:07
问题 I've seen this question asked a couple of times but nobody has answered it - in fact it might be impossible, but I was wondering if there was a way to prevent the screen from going black when the proximityState changes on the iPhone? I have implemented a method to do something when the proximity state changes, but the screen flickers to black and I want to avoid that. Here is my code: [nc addObserver:self selector:@selector(proximityChanged:) name:UIDeviceProximityStateDidChangeNotification

Elasticsearch complex proximity query

由 时光怂恿深爱的人放手 提交于 2020-01-01 10:50:56
问题 Given that I have a query like below: council* W/5 (tip OR tips) The above query can be translated as: Find anything that has council* and (tip OR tips) no more than 5 words apart. So following text will match: Shellharbour City Council Tip council best tip councils top 10 tips But this one should not match: ... City Council at Shellharbour. There is not any good tip at all. I need help to build an elasticsearch query for that. I was thinking about Regex query but I'm not quite sure about

Detecting another nearby android device via Bluetooth

由 本小妞迷上赌 提交于 2020-01-01 03:31:07
问题 Alright, I've got a bit of a weird question here. I'm working on an Android game where I'd like to be able to have Android phones detect the presence of each other. The device searching for other players will know the bluetooth mac addresses of the other players' devices (from a game DB), however the devices will not be paired and the devices will not be in discoverable mode. Also, there will only be a handful of devices that could possibly be found - so it's not a big deal to scan through
