  • Data Architecture Knowledge & Programming Skills: Many companies have compartmentalized the standard job responsibilities of a typical Data Scientist (Data Analyst, Data Engineer). Although this may be useful for labor division within the organization, a Data Scientist must be able to extract and manipulate data. In a typical data science project, data preparation and analysis account for more than 80% of the work.

What is Data Science?

To extract value from data, Data Science combines multiple fields such as Statistics, Scientific Methods, Artificial Intelligence (AI), and Data Analysis. Data scientists are individuals who use a variety of skills to analyze data collected from the web, smartphones, customers, sensors, and other sources to derive actionable insights.

Data Science refers to the process of cleansing, aggregating, and manipulating data to perform advanced data analysis. The results can then be reviewed by analytic applications and data scientists to uncover patterns and enable business leaders to make informed decisions.

The Data Science lifecycle is divided into five stages, each with its own set of responsibilities:

  • Capture: Data collection, data entry, signal reception, and data extraction are all steps in the data collection process. This stage entails gathering unstructured and structured data in its raw form.
  • Maintain: Data Warehousing, Data Cleansing, Data Staging, Data Processing, and Data Architecture are all terms that can be used to describe the processes that are used to prepare data. This stage entails converting raw data into a usable form.
  • Process: Data Mining, Clustering/Classification, Data Modeling, and Data Summarization are the steps involved in the process. Data scientists examine the prepared data for patterns, ranges, and biases to see if it can be used in predictive analysis.
  • Analyze: Exploratory/Confirmatory, Predictive Analysis, Regression, Text Mining, and Qualitative Analysis are some of the methods that can be used to analyze data. This is where the lifecycle gets going. This stage entails conducting various data analyses.
  • Communicate: Data Reporting, Data Visualization, Business Intelligence, and Decision-Making are all concepts that should be explained. Analysts prepare the analyses in easily readable forms such as charts, graphs, and reports in the final step

What is the Importance of Data Science?

Companies may foresee, prepare, and optimize their operations using data science as a guide. Furthermore, data science is critical to the user experience; many organizations rely on data science to provide personalized and personalized services. Streaming services like Netflix and Hulu, for example, might propose entertainment based on a user’s previous viewing history and taste preferences. Subscribers spend less time looking for something to watch and may quickly find value among the hundreds of options, resulting in a unique and personalized experience. This is significant since it improves subscriber convenience while also increasing client retention.

What are the Steps to Master Data Science Kaggle?

You can master Data Science Kaggle by implementing the following steps:

Master Data Science Kaggle Step 1: Build your Basics

To master anything, you should first understand its basics. In order to master Data Science Kaggle, it is necessary for the learners to first equip themselves with basic programming skills. If you do not have solid foundations and a strong grip on basic language skills, Kaggle could be very overwhelming for you and this lack of skill can stop your learning journey before it even starts. You need to first build your basic knowledge in the following before working on Kaggle:

  • Programming languages: Before getting started with Kaggle, you need to get familiar with the level of your competency and then identify the points on which you have to work to reach that level of competency where you are comfortable with a programming language like Python or R since it is primarily used on Kaggle for Machine Learning applications. So if you are aware of these programming languages and know how to code in them, it would help you understand the code snippets available on Kaggle to analyze data.
  • Libraries & Packages: Once you have an in-depth knowledge of Python or R programming, the next step is to discover and explore the relevant libraries and the packages that the language is offering. As the notebooks in Kaggle use these libraries and packages, having background knowledge of these libraries would be a great help to understand the code snippets.
  • Algorithms: Along with programming languages and libraries, algorithms are also one of the essential components of Data Science and Machine Learning. Before diving in, you must have in-depth knowledge of algorithms and the use cases where they are applicable. This would help you understand the algorithms and their application.

Once you are done with the basics, you are now able to understand the essence of the discipline. Now you can learn the advanced techniques with great ease and comfort as you have taken the first step in the right direction.

Master Data Science Kaggle Step 2: Get Hands-on Experience with Data Sets

Data Science is incomplete without datasets. It is all about the manipulation of data using different techniques and tools. If you are a beginner in the field of Data Science, then start with dataset exploration. Begin with small and less complex data sets that are easy to import, visualize and analyze. Moreover, choose the datasets from the domain in which you are interested because your interest would help you better understand the data. While exploring the datasets, check their descriptions. The description would ideally include the following:

  • The details about how the data was gathered.
  • The time period over which the data was collected.
  • The domain from which it belonged.

This information would help you form questions for your Exploratory Data Analysis in later stages. You should keep exploring the datasets to get hands-on experience with handling datasets. Try to explore different types of datasets, get out from your comfort zone gradually and introduce yourself to the datasets of the domains you have not worked with. Analyze those datasets and submit your analysis to see how the community evaluates your analysis.

Master Data Science Kaggle Step 3: Exploratory Data Analysis

Now you have hands-on experience with the basics of programming and discovering and exploring datasets. It’s time to learn about Data Analysis. For analysis, get back to the datasets you have worked on, go to the Notebooks tab and search for the code snippets by expert members with the most upvotes. Compare your analysis with what has been done through that code. Identify the points where you lacked and check your analysis gaps. This comparison would help you to make your analysis better.

You can also check the other datasets that you have not analyzed yet, go through their analysis scripts, and understand the analysis done. Similarly, do visit the analysis of experts to broaden your horizon and to learn more efficient techniques of analysis.

Once you have been gone through an expert‘s analysis, try to implement some of the insights you got on your own. You can select a new dataset and start analyzing it by incorporating different standards such as documenting and formatting scripts to make them easy to read and understand.

This is one of the most crucial steps in the journey of building successful data models. The more time you will spend on it, the more enhanced your analysis becomes. So make sure that you are spending enough time to explore and learn from experts of data analysis.

Master Data Science Kaggle Step 4: Explore the Notebooks

Now, as you have sharpened your analysis skills by following expert techniques and picking different types of datasets, it’s time to build your own Predictive Data Model. Select the notebooks solving use-cases and try to understand the logic of those code snippets by re-executing them line by line.

After exploring the Predictive Models, take a step ahead and try to explore the notebooks with other solutions like models for a Recommendation Engine. Exploring the variety of solutions and understanding them would be helpful to enhance your understanding of the analysis of data and building solutions by using it.

Tips for Kaggle Data Science

  • Set incremental goals: If you’ve ever played an addictive video game, you’ve probably experienced the power of incremental goals. That you’ll be able to connect with others while playing good games. Each goal is ambitious enough to give you a sense of accomplishment while also being precise enough to be achieved. It’s perfectly acceptable for the vast majority of Kaggle users to never win a single competition. If that is your first goal, you may become discouraged and lose interest after a few attempts.
  • Review the most popular kernels: Kaggle allows participants to submit “kernels,” or short scripts that explore a concept, demonstrate a technique, or even share a solution. When you’re starting a competition or when you’ve reached a stalemate, reviewing popular kernels can help you come up with new ideas.
  • Pose a question in the discussion forums: Don’t feel bad about asking “stupid” questions. After all, what’s the worst that could happen? Perhaps you’ll be overlooked… and that will be the end of it. On the other hand, the advice and guidance of more experienced data scientists will be extremely beneficial to you.
  • Work alone to develop skills: At first, working alone is recommended. This will encourage you to complete all steps of the applied machine learning process, including exploratory analysis, data cleaning, feature engineering, and model training. If you start teaming up too soon, you might miss out on opportunities to develop those crucial skills.
  • Join forces to push your boundaries: As a result, teaming up in future competitions can be a great way to test your limits while also learning from others. Many of the previous winners were made up of individuals who pooled their knowledge. Furthermore, once you’ve mastered machine learning’s technical skills, you’ll be able to collaborate with others who may have more domain knowledge than you, further broadening your horizons.
  • Remember that Kaggle can serve as a stepping stone: Keep in mind that you’re not signing up to be a Kaggle for the long haul. It’s not a big deal if you don’t care for the format. Many people use Kaggle as a preliminary step before starting their own projects or pursuing a full-time career as a data scientist. Another reason is to focus on gaining as much knowledge as possible. In the long run, it’s better to concentrate on competitions that will give you relevant experience rather than chasing the biggest prize pools.
  • Don’t get too worked up about your low rank: Because they are concerned about their profile showing low ranks, some beginners never start. Of course, competition anxiety is a real thing that isn’t limited to Kaggle. On the other hand, low rankings aren’t a big deal. No one else will judge you because they were all beginners once. If you’re still worried about your profile’s low rankings, you can create a practice account to learn the ropes. When you’re ready, use your “main account” to begin constructing your trophy case.
