阅读更多关于 predict function for MaxEnt(Software R)

问题 I'm trying to use predict function for predict potencial occurrence points in space transfer. For this I using dismo package loaded with presence points in original space, 17 raster layers for original space and 17 raster layer for transfer space. All the rasters are identicals in extent, grid resolution and dimension, differing only in geographic coords. The original space and the transfer space are located in different continents and I have used kfold techinque for partitioning of my

pyhanlp 两种依存句法分类器

依存句法分析器在HanLP中一共有两种句法分析器 ·依存句法分析（1）基于神经网络的高性能依存句法分析器（2）MaxEnt依存句法分析基于神经网络的高性能依存句法分析器 HanLP中的基于神经网络的高性能依存句法分析器参考的是14年Chen&Manning的论文（A Fast and Accurate Dependency Parser using Neural Networks），这里还有一个发在了Github的实现程序，其实现语言为Python。除此之外，你还可以参考ljj123zz 的CSDN 一篇博客：blog.csdn.net/ljj123zz/article/details/78834838 HanLP作者的原文介绍已经写得比较清楚，唯一要注意的是原文章中介绍的依存句法分析器为早期版本，输出的依存关系为英文，现在应该变为中文，而且从测试结果看，训练语料应该已经更新了，但是更新为了那个语料现在还不会是很清楚。（hanlp开源项目负责人hankcs）基于最大熵的依存句法分析器经过测试这个句法分析器为真的很坑，绝对不建议使用,测试代码见最后，作者原文介绍请点击击www.hankcs.com/nlp/parsing/to-achieve-the-maximum-entropy-of-the-dependency-parser.html 下面是使用的例子

maxent软件数据格式要求

【今日推荐】：为什么一到面试就懵逼！>>> 软件数据格式要求坐标投影要相同，栅格范围一致。其中，样本文件要求CSV格式；环境变量要求asc格式。对样本和环境变量数据进行统一投影后，样本点数据，可以使用arcgis的字段计算器起算样本点的坐标，然后到处Excel表；环境变量数据使用研究范围批量裁剪后，将格式转换为asc格式即可。目前，51CTO网站已有maxent软件使用教程。视频教程网址： https://edu.51cto.com/center/course/lesson/index?id=542281 来源： oschina 链接： https://my.oschina.net/u/4376318/blog/3232739

Training models using openNLP maxent

阅读更多关于 Training models using openNLP maxent

问题 I have gold data where I annotated all room numbers from several documents. I want to use openNLP to train a model that uses this data and classify room numbers. I am stuck on where to start. I read openNLP maxent documentation, looked at examples in opennlp.tools and now looking at opennlp.tools.ml.maxent - it seems like it is something what I should be using, but still I have no idea on how to use. Can somebody give me some basic idea on how to use openNLP maxent and where to start with?

问题 I am trying to create the java implementation for maxent classifier. I need to classify the sentences into n different classes. I had a look at ColumnDataClassifier in stanford maxent classifier. But I am not able to understand how to create training data. I need training data in the form where training data includes POS Tags for words for sentence, so that the features used for classifier will be like previous word, next word etc. I am looking for training data which has sentences with POS
