Data Science certification

There was a lot of training through professional practice, Massive Open Online Course, and online communities when I began my journey to where I am right now. I hope it’s time to begin giving back to the field of data science, and I’m beginning my blog with something I thought I wanted to talk about. Before starting the blog, I’d suggest all Data Science enthusiasts to get Data Science certification to get started.

This post is targeted at people who are ready (or changing to) your Data Science careers and are prejudiced about some of the facts relevant to professional knowledge.

Learn traditional Machine Learning before starting Deep Learning

I recommend this for two major reasons. 

One: You should enjoy discovering hidden details. The best way to start will be standardized data, and the method includes bi-variate analysis, a few theories being checked, incomplete data care, outlier detection, etc. 

Two: You can go through the interesting project of variable collection, function engineering, adjusting parameters, and finally testing model variables for business implications. Communication network, on the other hand, takes care of much of the quality engineering component of deep learning, and hyper-parameter balancing becomes an integral part of the process. It is still an essential part of any project to describe the model to the decision-makers and therefore the intuitiveness of the machine learning models in terms of variable value (such as logistic regression, random forest) makes them the most sought-after alternative in many industries (for complex information).

Don’t get overwhelmed by the resources available

Actually, you are going to get lost in the digital learning field of Data Science at some point in time. In order to become a professional, it doesn’t mean you have to finish all of them. You should build your learning paths and set standards are based on:

  1. In order to process one blog a day, maintain a target. Write down two things you should take home with you. 
  2. Prepare a learning path based on the purpose and the method selected above. 
  3. Ultimately, continuity is the secret to
  4. Use one thing and finish it at a time. Let it be a course on Coursera, a Kaggle 
  5. project or the design of your tableau dashboard.
  6. First of all, understand what kind of strategy you want to take; top-down or bottom-up. I am a former type of people who would like to know enough theoretical information before jumping into applying it, but it depends solely on the individual.
  7. Making your own records for any learning experience.

Structured Query Language — The most underrated tool.

Structured Query Language is to Data Science what Indian Cricket was to Gautam Gambhir. If you don’t get a great approach, you’ll fail during the winnings, yet still, often, you’ll be overlooked by the winning sixers.

Structured Query Language is used, after all, to retrieve some data. But assume, on the services in the form dataset, you did the whole modeling exercise to understand that the data has customer duplicates due to some of the incorrect ‘Structured Query Language connects’ during data wrangling. Duplication is a big issue when retrieving data, and this could be due to your Structured Query Language code or backend database problems. During every process of Structured Query Language data wrangling, proper quality evaluation is needed because “executing without syntax error does not mean it has executed the way you wanted it to be.”

Most of the resources teach the basic Structured Query Language for beginners, concentrating on having the syntax portion, and the notion that Structured Query Language logic is so simple and sometimes ignored is spread. I would suggest that you take a relational database on various subjects (E-commerce, Airlines, Retail, etc.) (set of 3-10 tables) and ask some difficult business questions. This will take many Structured Query Language blocks to be executed and will test your skills sufficiently.

Not every problem ends up in building models

The art of data science does not include constructing the best model, but using data as an asset to solve the issue. 

In the market, there are also other common methodologies and methods that are commonly used.

  1. Design of Experiments — It is always important to know how particular services/campaigns/progress perform and it is vital to evaluate their effect in order to make important decisions. The testing will typically be used here to measure the effect of test control analysis.
  2. Dashboarding and Reporting — It is an important component of many companies, including the development of automated data storage using Structured Query Language thinking up with clients to ensure Key Performance Indicators, novel telling with a clear visual aesthetic narrative.
  3. Segment the data till you can — With properly built Explanatory Data Analysis and differentiation, such problems can be easily resolved. I would recommend that you select areas of interest for beginners and find appropriate data sets (movies, sports, etc.). Build public dashboards with Tableau/R Shiny that hold two things in mind. How well the data flows and how simply the knowledge is reflected in your graph. Study case studies where the attention is on developing and formulating solutions to such issues, too.

Things that hackathons don’t teach you — Defining the Problem

By applying machine learning techniques to the already given raw (not-so-raw clearly) a dataset with a simple statement of the problem, most users become stylish. These problem statements unwittingly simplify some things, such as the problem description, the final dataset achievement, the assessment metric definition, etc. But this isn’t the case in the real world.

Find open-source sets of data, come up with your theory, ask himself what issues this data set can solve, think about what other applicable data you might use to solve this to start off this problem-solving. You could end up solving your problem with some beautiful visualizations’ using a t-test.

R or Python? Learn both.

There are many various blogs on this subject also and Python will be the champion if you read any of them for a small profit). I don’t want to go through each one’s advantages and disadvantages and conclude something, but I’d recommend you practice both and get experience in one. 

Let’s say, R was introduced to Mr. Race-R. He enjoyed the intuitiveness of dplyr during his trip, he thought that after his girlfriend, ggplot2 is the new wonderful thing and his oneliner stylish decision tree plot works like a charm. And unexpectedly, one day, with a wonderful opportunity, he meets an appointment call from his ideal company. 

Because I dramatized the story, to the point that changing becomes very fast, the moral is to educate and get relaxed in both (it may be because of a shift at work, user need, managed data problems, better availability of bundles, etc.). Languages, after all, are just the means to get things done. You never know that a third language is waiting for a storm to crack.
