EDA(Exploratory Data Analysis)数据探索性分析 EDA目的:通过了解数据集的分布情况,数据之间的关系,来帮我们更好的后期进行特征工程和建立模型。本文主要是一个根据coco数据集格式的json文件,来分析数据集中图片尺寸,宽高比,bbox尺寸,宽高比,以及每张图片中bbox数量的分布情况。分析...
Working with unstructured data The Data Discovery solution for unstructured data aims to quickly provide structured views on your text, images and videos. All at scale using Synapse and unsupervised ML techniques that exploit state-of-the-art deep learning models. The goal is to present this data...

multidimensional datacognitive imagesThe new method for visualization of multidimensional data, where the perception of multidimensional space realized the projection of multidimensional data on low-dimensional space (2, 3-D) by their partition emanating from the origin rays, equal to the number of ...
Manipulate analysis parameters and receive real-time visual feedback Creating graphics Graphic elements can be simple geometric shapes—rectangles, circles, lines, or points—or they can be complex polygons, linear or curved text, or images. When a graphics layer is added to a map in ArcGIS ...

Donoho traces the genesis of data science back to Tukey’s pioneering work in data analysis.Elements of Structured Data Data comes from many sources: sensor measurements, events, text, images, and videos. The Internet of Things (IoT) is spewing out streams of information. Much of this data ...
Exploratory Data AnalysisExploratory data analysis, which is concerned with summarizing and visualizing data as a starting point for more detailed analyses, is the subject of this chapter. We restrict ourselves to numerical data (as opposed to text or images) and note that: (a) data can be ...
Outliers(离群值)指的是那些不寻常(unusual)的observations,哪些看起来不符合模式的数据点(data points)。有时候outliers是数据输入错误,其他时候可能会表明重要的新科学。当你有很多数据的时候,outliers很难从直方图中看出来。例如下图,你只能从x轴上有不寻常的宽度限制看出有异常值。
