A megalopolis six times the size of New York, JingJinJi will ease the pressures being faced by China’s capital Beijing.

If you thought that China’s cities are massive, think again. China’s urban planners are hard at work creating new megalopolises that will redefine our understanding of cities as we know them. One of them—nicknamed JingJinJi—will transform Beijing and its surrounding areas into a city six times the size of New York. So what is JingJinJi? It stands for Beijing (‘Jing’), Tianjin (‘Jin’) and Heibei Province (Hebei is known by the one character abbreviation ‘Ji’, which was its name during the Han dynasty).

China’s Politburo officially approved the JingJinJi Common Development Guideline on April 30th, 2015. Beijing, Tianjin and Hebei together account for up to 2.3% of China’s territory and 8% of China’s 1.37 billion population. The signs are already there. Poor quality of life due to such inconveniences have forced many to leave the capital. Maven Tutorial for Beginners : with Eclipse. Untitled. Eigenvectors and Eigenvalues explained visually. Loading [MathJax]/jax/output/HTML-CSS/jax.js Explained Visually By Victor Powell and Lewis Lehe Eigenvalues/vectors are instrumental to understanding electrical circuits, mechanical systems, ecology and even Google's PageRank algorithm.

Eigenvectors and Eigenvalues explained visually

Let's see if visualization can make these ideas more intuitive. To begin, let v be a vector (shown as a point) and A be a matrix with columns a1 and a2 (shown as arrows). If you can draw a line through the three points (0,0), v and Av, then Av is just v multiplied by a number λ; that is, Av=λv. Dive Into NLTK, Part IV: Stemming and Lemmatization – Text Mining Online.

Dive Into NLTK, Part IV: Stemming and Lemmatization – Text Mining Online

The goal of both stemming and lemmatization is to reduce inflectional forms and sometimes derivationally related forms of a word to a common base form. Here is the definition from wikipedia for stemming and lemmatization: Stemming: Speech recognition - Hello world for spoken NLP interaction (like Siri)?

Nlp - NLTK Named Entity recognition to a Python list. User Ashwini Chaudhary. Building Language Model [CMUSphinx Wiki] There are several types of models that describe language to recognize - keyword lists, grammars and statistical language models, phonetic statistical language models.

Building Language Model [CMUSphinx Wiki]

You can chose any decoding mode according to your needs and you can even switch between modes in runtime. Keyword lists Pocketsphinx supports keyword spotting mode where you can specify the keyword list to look for. The advantage of this mode is that you can specify a threshold for each keyword so that keyword can be detected in continuous speech. All other modes will try to detect the words from grammar even if you used words which are not in grammar. GitHub - attardi/wikiextractor: A tool for extracting plain text from Wikipedia dumps. Carinh’s Documents on SlideShare. Buy Authentic Louis Vuitton Handbags from Factory Outlet. Using colours in LaTeX. There are several elements in LaTeX whose colour can be changed to improve the appearance of the document.

Using colours in LaTeX

Colours can be manually defined to a desired tone using several models, this article explains how. [edit] Introduction The simplest manner to use colours in your LaTeX document is by importing the package color or xcolor. Both packages provide a common set of commands for colour manipulation, but the latter is more flexible and supports a larger number of colour models. Coursera - Free Online Courses From Top Universities. Word Search II. Given a 2D board and a list of words from the dictionary, find all words in the board.

Word Search II

Each word must be constructed from letters of sequentially adjacent cell, where "adjacent" cells are those horizontally or vertically neighboring. The same letter cell may not be used more than once in a word. For example, Given words = ["oath","pea","eat","rain"] and board = [ ['o','a','a','n'], ['e','t','a','e'], ['i','h','k','r'], ['i','f','l','v'] ] Return ["eat","oath"]. A Guide to Python Frameworks for Hadoop - Cloudera Engineering Blog. I recently joined Cloudera after working in computational biology/genomics for close to a decade.

A Guide to Python Frameworks for Hadoop - Cloudera Engineering Blog

My analytical work is primarily performed in Python, along with its fantastic scientific stack. It was quite jarring to find out that the Apache Hadoop ecosystem is primarily written in/for Java. So my first order of business was to investigate some of the options that exist for working with Hadoop from Python. In this post, I will provide an unscientific, ad hoc review of my experiences with some of the Python frameworks that exist for working with Hadoop, including: Machine Learning vs. Natural Language Processing, part 1 - Lexalytics. (Note: Updated July 2, 2015) What is Machine Learning?

Machine Learning vs. Natural Language Processing, part 1 - Lexalytics

Machine Learning (in the context of text analytics) is a set of statistical techniques for identifying some aspect of text (parts of speech, entities, sentiment, etc). The techniques can be expressed as a model that is then applied to other text (supervised), or could be a set of algorithms that work across large sets of data to extract meaning (unsupervised). Supervised Machine Learning Take a bunch of documents that have been “tagged” for some feature, like parts of speech, entities, or topics (classifiers). Some model types you’ll see fairly frequently. A Guide to Python Frameworks for Hadoop. Writing An Hadoop MapReduce Program In Python. In this tutorial I will describe how to write a simple MapReduce program for Hadoop in the Python programming language.

Writing An Hadoop MapReduce Program In Python

Even though the Hadoop framework is written in Java, programs for Hadoop need not to be coded in Java but can also be developed in other languages like Python or C++ (the latter since version 0.14.1). However, Hadoop’s documentation and the most prominent Python example on the Hadoop website could make you think that you must translate your Python code using Jython into a Java jar file. Creating a great data science resume. I hear a familiar story from a lot of aspiring data scientists: “I have sent out my resume to 25 companies, and I haven’t heard back from any of them!

Creating a great data science resume

I have pretty good skills, and I think I have a pretty good resume. I don’t know what’s going on!” Your resume probably sucks My immediate conclusion after hearing your story: your resume probably sucks. If you are not getting any responses from any companies, and your skills are a reasonable match for the job description, then it almost certainly means that you are getting sabotaged by a bad resume.

Automate the Boring Stuff with Python Programming. If you're an office worker, student, administrator, or just want to become more productive with your computer, programming will allow you write code that can automate tedious tasks.

This course follows the popular (and free!) Book, Automate the Boring Stuff with Python. Automate the Boring Stuff with Python was written for people who want to get up to speed writing small programs that do practical tasks as soon as possible. You don't need to know sorting algorithms or object-oriented programming, so this course skips all the computer science and concentrates on writing code that gets stuff done. Improve Your Python: Python Classes and Object Oriented Programming.

The class is a fundamental building block in Python. It is the underpinning for not only many popular programs and libraries, but the Python standard library as well. Understanding what classes are, when to use them, and how the can be useful is essential, and the goal of this article. In the process, we'll explore what the term Object-Oriented Programming means and how it ties together with Python classes. Everything Is An Object... 40 Terminal Tips and Tricks You Never Thought You Needed.

The Terminal is an exceptionally powerful tool, providing a command line interface to the underpinnings of OS X. It’s a topic we’ve covered at length before with our popular series Taming the Terminal. There’s a great deal that Terminal can do, from moving large numbers of files to changing preferences that we didn’t even know exist. To demonstrate just how versatile the Terminal is, I’ve rounded up 40 truly excellent Terminal tips and tricks that can come in very handy. All of the Terminal commands I’ll be showing you are perfectly safe to use and, when it comes to changing preferences, are completely reversible.
