DATA SCIENCE BASICS

In this post, we’ll be discussing about two fundamental questions which can assist you in shaping your career in data science.
1 . What is data science and what are its components?
2. What are the prerequisite skills needed to get a job in data science?
1 . Data science is actually the techniques which are used for extracting meaningful insights from a huge dataset. With the presence of many people on the web , companies like Facebook, Instagram, Google collected plenty of knowledge about its users. This led to Big Data. It comprises of unstructured datasets. Hence, several methods were developed to work on this data and are available up with wide scale applications. An example is that Netflix collects data from its users to return with the choices like where to put subtitles, the way to place the top credits and the way to make transition between episodes of an internet series.
So the first step is to collect data and store it. It involves collecting differing types of knowledge like user generated data, external data and storing them.
To ensure the reliable flow of knowledge , data pipelines are built on the idea of a standard structure, ETL which is Extract, Transform and cargo . Through this, the transformation of raw data is done so that it can be suitably analysed. This task is handled by data engineers.
Only after this, the “analysis” on data can be performed. Often this is often the sole part which is concentrated ignoring the essential foundations, hence people have the misunderstanding that only data analytics comprise data science.
On top of this, metrics are built on which data is tracked, categorisation of users is completed and data also can be trained with the assistance of labels. Before deploying ML models, an experimentation framework is put for getting an estimate of the changes before it’s implemented on the whole dataset.
2. Now to be able to implement it, you need the following skills for getting started in the domain of data science.
Programming LanguageIrrespective of the role, you would like to understand a programing language suitable for manipulating statistical data like Python or R. Besides this, you furthermore may got to know a database command language like SQL. With the help of Python libraries, the application of machine learning models get simpler hence it is not required to know how exactly the algorithms work initially.

Applied Mathematics You should have a solid understanding of statistics, as it will be needed for making decisions for evaluation of experiments. Knowledge of calculus and linear algebra helps in using the results of a machine learning or statistical implementation in a different case independently.
Data cleaning and visualisationDo not think that data will be readily available to you for processing. Often an excellent deal of your time is spent in cleaning the info , adjusting missed values, correcting formatting. Without this, data can’t be processed to further stages.
You should skills to use visualisation techniques to draw meaningful insights from the info . Matplotlib, ggplot can help in visualisation. Tableau has also been a well-liked tool for rendering data visually.
Software engineeringA strong software engineering background is that the most essential requirement. You should have a clear understanding of algorithms, data structures, memory management which will be always tested in the first rounds for the data science roles.

How to fix the Hulu error code 5003.

Hulu is known as one of the most popular and entertaining streaming service across the world. It fulfills the user demands by allowing to them stream popular TV shows. It is owned by the Walt Disney company and was founded in 2007.

If Women Ruled the World

Our world has been male dominated since time immemorial. In this male dominated world people have become habitual to men leaders and they often hesitate in being lead by a woman, because women are portrayed as the weaker gender who didn’t possess sufficiennt qualities that are needed for being a leader.


Even with limited opportunities and encountering difficulties like gender stereotypes, bias, absence due to motherhood they outshine men in every sphere of life.


Women in comparison to men are much more efficient at handling tough and unprecedented situations and this pandemic has proved that enough. In this global pandemic countries with male leaders like Greece, Czech Republic, Australia have done well but countries with female leaders have done extremely well and have responded in a much better way than those with male leaders .


It may be argued that female leaders have walked into the current crisis with a few plus points over countries with men leaders but the handling of crisis by Germany led by Angela Merkel has proved that also wrong. Germany with 83 Million citizens has had over 1,84,00 infections but very low deaths per million far lower than most other European countries. Germany has achieved far lower death rate than Britain, France, Italy or Spain because of its approach of large scale testing programme. It has recorded highest testing programme in Europe conducting 3,50,000 tests each week detecting the virus early enough to isolate and treat patients effectively.


Its neighbouring country Denmark also responded equally well, the Prime Minister Mette Frederiksen closed the borders of the country on 13th March followed by closing educational institutions and prohibiting gathering of more than 10 people limiting its cases to 12001 with less than six hundred virus related deaths.


Four of the five Nordic countries are led by women. Countries like Finland, Iceland and Norway also performed outstandingly well during the crisis by taking early actions and adapting smart methods for eradication of the virus.

Expect Sweden the only Nordic country not led by a woman – where Prime Minister Stefan Löfven refused to impose a lockdown which resulted into a far higher death rate in of most other European countries.


Finland where Sanna Marin governs recorded less than 10% as many deaths as nearby Sweden.


Iceland Prime Minister Katrin Jakobsdottir early and aggressive intervention helped the country in its battle with the virus.


Taiwan President TsaI.Ing Wen early intervention helped the country in limiting the outbreak . Its aggressive testing, tracing and isolation measures are applauded all over the world.


New Zealand an island country of five million which heavily relies on tourism has been declared as one of the first COVID-19 free countries in the world imposed a nationwide lockdown on 23rd March much before that its international boundaries were sealed and 14 days quarantine was already imposed on anyone entering the country. With widespread testing and effective approaches the country has eradicated the virus and is the among the firsts in going back to normal.

When the leaders of worst affected countries USA, Brazil, Britain and India were busy in making their citizens believe that the light will never fade out and they will defeat the virus with the very few restrictions adopted by them at that time these female leaders understood the severity of the situation and employed effective measures and approaches to not only curb the spread of virus but also eradicate it from their countries.


The distinguished approaches of these women leaders helped them in minimizing death rates in their countries .


Women hold only 7% of the world’s government leadership roles. Yet they have proved themselves . If there would have been more female leaders the scenario would have been much better. In spite of limited opportunities they performed so well if they are provided with equal opportunities in the near future they will definitely make the world a better place to live in.


In the midst of pandemic when the entire world is battling against a virus comparing the performance of countries would be incorrect as all countries are very different from each other because of their geographical boundaries and population but highlighting the approaches adopted by countries with better performance isn’t wrong at all.
