R – your tool for data analysis

R‬ is a language and environment for Statistical Computing and Graphics. R provides a free/open source, cross­-platform, object-oriented environment to perform data analysis and visualisation tasks. Strength of R lies in its vibrant community, robust package repository and strong graphics capabilities. ‪
R provides all necessary tools required for various stages of a data analysis project. It provides techniques for data acquisition and processing as well as for data analysis and visualisation. It ranges from accessing data in various formats (CSV, XML…) to all possible ways of data manipulation (tabulation, aggregation…)to rich support for graphics (histogram, box plot etc.) to statistical models (regression, ANOVA…).
It is not always necessary to use built-in and supported functions and packages. Depending on the requirements, one can also develop his/her own functions, scripts and packages.
Recently, CDAC Mumbai has announced a 3-day course on R entitled “Using R for Data Visualisation and Analytics”. This course is aimed to cover in detail the features of R related to data analysis and visualisation. More details can be accessed here.

Call for Participation - Short-term Courses on Data Science at CDAC, Kharghar, Navi Mumbai

We are living in a Data Age. Data is being continuously generated and consumed in various formats, and sizes from a number of varied sources. This data can be a big asset if stored, processed and analysed efficiently in real time with the help of intelligent algorithms. There is a growing interest to utilize such data for the improvement of business, health, education, society, etc. There are many ways to process and analyse such data spanning techniques like data visualisation, text analysis, predictions and recommendations etc. Applications of these techniques can give companies and organisations valuable insights leading to competitive advantage, efficient service delivery and above all customer satisfaction. And so the demand for skilled resources in these fields is growing day by day.
With this view, CDAC, Mumbai is announcing the following short-term courses in Data Science and Machine Learning.
  1. Using R for data visualization and analytics: This course introduces R – a language and environment for Statistical Computing and Visualisation. In recent years, R has become very popular due its open source cross-platform nature, robust package repository and strong graphics capabilities. During the course, one will not only learn about basics of R, but also about techniques of data acquisition and processing. Course will also cover in detail the features of R related to data analysis and visualisation.
  2. Text Analytics: The course aims to provide learners an understanding of the methods for text analytics. It will cover major techniques for mining and analyzing text data to discover interesting patterns, extract useful knowledge, and support decision making. The techniques will include Named Entity Recognition, Sentiment Analysis and Text Categorization among others. Learners will also be introduced to various open source utilities for developing text analytics applications.
  3. Predictive Analytics and Recommender Systems: The course covers various methods of Predictive Analytics and Recommender Systems drawn from Statistics, Data Mining, and Machine Learning. We will discuss popular algorithms in the domain and their use in various applications. The course emphasizes hands-on approach for better understanding of the techniques used in the domain. During the course, mainly open-source tools will be used for illustrations and lab.
Target Audience: Individuals, students, and professionals from government, industry, and academia working / interested in Data Science

How a rainbow works - Elocution speech by Harshi

  • A rainbow is a multi-coloured arc that appears in the sky as a result of bending and scattering of sunlight through drops of rain.
  • It occurs when it is raining in one part of the sky and sunny in another.
  • A rainbow cannot be approached or physically touched.
  • On ground, we only see a semi-circle or arc of rainbow, though it’s a full circle of light. 
  • However, from height such as on an airplane, it can be seen in a complete circle.
  • Due to its bow like shape and being formed mainly in rains, it is called as rainbow.
  • Sir Isaac Newton explained how a rainbow forms. He identified 7 colours that make up white light of Sun. These 7 colours are Violet, Indigo, Blue, Green, Yellow, Orange and Red (VIBGYOR).
  • All these colours are present in a rainbow in the order red, orange, yellow, green, blue, and indigo and violet.
  • Normally when sunlight travels through the air we see white light. But when it enters through a raindrop, colours separate to make a rainbow at 42 degrees from the direction opposite to the sun. Each raindrop makes its own rainbow but it takes millions of raindrops for us to see a rainbow.
  • Earth is the only planet in the solar system where rainbows are possible.
  • No two people see the same rainbow due to change in set of raindrops being seen.

How weather changes - An article by Harshi for her school's magazine

If one thing around us changes every day, it is possibly the weather. One fine day it is pleasant, another day it is rash. Some days are warmer, while some days are cooler or rainy. Ever thought why it happens. Come! Let’s discuss.
Our planet, “The Earth” revolves around “The Sun”, the only star of our solar system. The changes in weather are caused by the sun. Sun gives us light and heat. But the amount of heat received from sun is not same everywhere on the earth, as our earth is tilted on it axis. This heat is absorbed in the atmosphere of earth. Due to this, air in our atmosphere becomes warm.
Air near the equator (line which divides the earth in two equal parts) is warmest as it gets more heat than any other parts of atmosphere. On the other hand, north and south poles are cold due to being the farthest points on earth. It means air is hot on some parts of the earth, while cold on other parts. Air warmed by the sun becomes lighter and rises upwards in a warm place. Opposite to this in a cold place, air becomes dense and sinks. Hot air creates low pressure regions, while cold air creates high pressure regions. Air flows from these high pressure areas towards low pressure regions, thus creating wind or air current. This is a continuous process as the heat of the sun is continually received on earth.
Seasons in the northern and southern hemisphere differ largely due this flow of air. In a high pressure region, water vapor sinks before it can form the clouds. So, the weather is sunny. In a low pressure area, water vapor rises and forms clouds resulting in a rain.
Since the earth is tilted, hence at different times of the year, different parts of the earth surface are closer to sun in comparison to other parts. Areas close to the poles have very short summer and long winters. Similarly, areas near the equator have summer all the year. In the southern hemisphere, summer comes when this part is before the sun. While, in the northern one at the same time, winter is there.
Therefore, we can understand that all kinds of weather happen because the air around the earth blows in so many different ways, when heated by the sun.
Our country is lucky enough to have all kinds of weather like summer, winter, rain and autumn throughout the year.
