Data Science
If you are planning to begin your career in Data Science, then you are at right place. Advantages, using Big Data as an insight-generating engine has pushed the demand for data scientists at the enterprise-level across all industry verticals.
Data science is a multisectoral field of scientific methods, processes, algorithms and systems to extract knowledge or insights from data in various forms, structured or unstructured, similar to data mining.
Big Data Analytics or Data Science in IT industry terms, everyone appreciates it as a fancy term which is gonna help us to deal with this huge amount of data we are generating these days. Let us get knowledge of some important topics in Data Science, this are-
- Statistics
- Multivariable Calculus & Linear Algebra
- Programming
- Machine Learning
- Data Mining
- Data Visualization
- Statistics
Statistics is collecting numbers, looking at numbers, and concluding numbers. Knowledge of Statistics is extremely significant as this is the branch of Data analysis. Probability theory is also relevant to statistics and it mentioned as a prerequisite for learning machine learning.
Statistics include Descriptive Statistics (Mean, Median, Range, Standard Deviation, Variance), Exploratory Data Analysis, Percentiles and Outliers, Probability Theory, Bayes Theorem, Random Variables, Cumulative Distribution function (CDF), Skewness, Other Statistics fundamentals etc.
- Multivariable Calculus & Linear Algebra
Multivariable Calculus & Linear Algebra are quite powerful as they help us in understanding various machine learning algorithms which plays an important role in Data Science. Linear algebra is the branch of mathematics concerning vector spaces and linear mappings between such spaces.
- Programming
You need to acquire knowledge to various programming languages, such as Python, Perl, C/C++, SQL, and Java, with Python being the most common coding language required in data science roles. These programming languages help data scientists organize unstructured data sets.
Writing programs to automate tasks you can save precious time, but it can also be a reason for making your code much easier to debug, understand, and maintain.
Your written code is ultimately pointless if other programmers cannot understand it well enough to scale it and maintaining over time. Do not use hard values in the code, rather than use variables and inputs they are dynamic and will a scale over time opposed to entering any static values.
- Machine Learning
Machine Learning is one of the most prominent parts of data science and the most enthusiastic topic of analysis with researchers so, every year new developments are produced in ML. There are many libraries available in Python and R. Some of the libraries are-
Basic Libraries: NumPy, SciPy, Pandas, Ipython, matpolib
Libraries for Machine Learning: scikit-learn, Theano, TensorFlow
Libraries for Data Mining & Natural Language Processing: Scrapy, NLTK, Pattern
Weather, machine learning is a part of the field of Artificial Intelligence. Machine learning enables you to develop computers on how to program them so that you don’t have to write explicit instructions for certain tasks.
- Data Mining
Data Mining is a procedure to extricate valuable and essential information and knowledge from huge set/libraries of data. It is a process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.
Data mining has applications in varied fields, like science and research. From data mining, businesses can determine about their clients and develop more effective strategies related to various business functions and in turn leverage resources more optimally and insightfully. It is analogous to the gold mining where golds are extracted from rocks and sands.
- Data Visualization
Data visualization is an interdisciplinary field that deals with the graphic representation of data. It is a particularly efficient way of communicating when the data is numerous example of a time series.
Data Visualization is efficient to identify areas that need attention or improvement, clarify which factors influence customer behaviour, help you understand which products to put where and predict sales volumes and so on.
Data Visualization has few visualization tools like Tableau, Kibana, Google Charts, Datawrapper etc.
