How do I prepare for Msc in datascience at CMI in 2020 within one year?


Introduction:

I have been seeing people ask this question many times in quora as well as in conversations too. So I thought I will take time and I will answer this question outright in a blog post. So, two of my friends from ISI went through this exam this year. It depends on your background. I will suggest you prepare your statistics, probability, and general bachelor's level mathematics properly.


For basic level probability, I will suggest you go through Introduction to probability by Sheldon ross; read the concepts, solve the examples and proceed. This book is good enough to prepare you for the probability questions you will face.

Now, let’s come to the statistics part. For statistics, I will suggest reading through Casella Berger and CR Rao. See, these books are pretty rigorous, and maybe you can find it really hard for you. But, You can skip some of the hard theoretical parts, and follow the flow basically. That will give you a good knowledge of what can come.
Now, once all this is done, start with the question papers. I don’t know whether there is an interview part for this exam for all the candidates. In that case, you will have to go through some blogs or sites mentioning the questions asked in the interview. But prepare well on the previous year's questions; try to fetch similar questions from the above-mentioned books again. It may also help to try m.stat question papers from ISI websites which have solutions available on the internet also. But that is if you are done with all these previous steps.

Some advices and best of luck!

And above all, please try some data science projects hands-on before you end up doing a master's on it. You could be a karate master but maybe you will not like kicking people on a daily basis. A similar concept apply to data science. It may look fancy, but needs a lot of reading and researching along with programming skills to attain a bit of expertise even. So, look before you leap. Just do not run behind “data scientist is the hottest job of 21st century”. Maybe you are well determined and all; but I think it must be mentioned for people aspiring to become data analysts or data-science people.
So! best of luck for your exam!

Mastering SQL for Data Science: Top SQL Interview Questions by Experience Level

Introduction: SQL (Structured Query Language) is a cornerstone of data manipulation and querying in data science. SQL technical rounds are designed to assess a candidate’s ability to work with databases, retrieve, and manipulate data efficiently. This guide provides a comprehensive list of SQL interview questions segmented by experience level—beginner, intermediate, and experienced. For each level, you'll find key questions designed to evaluate the candidate’s proficiency in SQL and their ability to solve data-related problems. The difficulty increases as the experience level rises, and the final section will guide you on how to prepare effectively for these rounds. Beginner (0-2 Years of Experience) At this stage, candidates are expected to know the basics of SQL, common commands, and elementary data manipulation. What is SQL? Explain its importance in data science. Hint: Think about querying, relational databases, and data manipulation. What is the difference between WHERE

What is Bort?

 Introduction: Bort, is the new and more optimized version of BERT; which came out this october from amazon science. I came to know about it today while parsing amazon science's news on facebook about bort. So Bort is the newest addition to the long list of great LM models with extra-ordinary achievements.  Why is Bort important? Bort, is a model of 5.5% effective and 16% total size of the original BERT model; and is 20x faster than BERT, while being able to surpass the BERT model in 20 out of 23 tasks; to quote the abstract of the paper,  ' it obtains performance improvements of between 0 . 3% and 31%, absolute, with respect to BERT-large, on multiple public natural language understanding (NLU) benchmarks. ' So what made this achievement possible? The main idea behind creation of Bort is to go beyond the shallow depth of weight pruning, connection deletion or merely factoring the NN into different matrix factorizations and thus distilling it. While methods like knowle

Spacy errors and their solutions

 Introduction: There are a bunch of errors in spacy, which never makes sense until you get to the depth of it. In this post, we will analyze the attribute error E046 and why it occurs. (1) AttributeError: [E046] Can't retrieve unregistered extension attribute 'tag_name'. Did you forget to call the set_extension method? Let's first understand what the error means on superficial level. There is a tag_name extension in your code. i.e. from a doc object, probably you are calling doc._.tag_name. But spacy suggests to you that probably you forgot to call the set_extension method. So what to do from here? The problem in hand is that your extension is not created where it should have been created. Now in general this means that your pipeline is incorrect at some level.  So how should you solve it? Look into the pipeline of your spacy language object. Chances are that the pipeline component which creates the extension is not included in the pipeline. To check the pipe eleme
