15 Essential Tips That Will Help You to Learn Data Science

Nowadays, the need to go to an educational institution to learn a trade is slowly growing slimmer by the day. Technical skills are the most prone to be self-taught by using different materials available online in the form of blog posts, YouTube videos, and other different content. 

However, using this content efficiently is what really matters and it is the fastest and most efficient way to learn data science. How can this be done? Here are 15 essential tips that will help you to learn data science quickly and efficiently:

Get a data set

The first and foremost thing to do when entering the data science industry is getting an interesting data set to use. It is very easy to procure a data set nowadays because you can buy one online or from a local reliable supplier. 

Some prefer Xiaming Chen public datasets and some use data repositories such as datahub.io. For those that can’t manage with those setups, they can use public APIs to collect the data they need. 

Understanding statistics

Analyzing data requires a good understanding of statistics, so acquiring more knowledge of them is very beneficial. After procuring your data set, get used to it and befriend yourself with basic descriptive statistics. 

Should the data set you got include numerical variables, get to know their distributions such as the mean and their spread. Knowing statistics will equip you with understanding different factors analyzing data.

Machine Learning

Machine learning algorithms are based on making decisions based on data received. Also, machine learning systems are made to improve the data received. 

For example, each Amazon client has a different catalog because it learns your preferences as you log in and browse. Studying Machine Learning is an important part of understanding data science and is a great stepping stone to this industry.

Pre-processing: Standardization and Time Alignment

In one project, data scientists used the 28 sensors to derive data from. The sensors were monitoring an operation rotor to work on FFT pre-processed sensor. The FFT transform resulted in an output which was a matrix of spectral amplitudes for a time-segment and relative frequency value. The frequencies and time references were standardized by binning values to 100Hz wide bands and the timing was binned to dates.

Spectral Amplitudes were calculated to average each date and frequency bin and the results were 313 FFT spectral amplitude columns in total in consideration of all sensors. The data was provided considering cells that were part of the FFT matrix that referred to a one date and one frequency band assigned to a singular sensor.

This test is one example that shows how standardization and time alignment can be done and with data science, a heatmap of the test can be produced.

Using Time Series Analysis to predict anomalies

In the time series analysis conducted above, data that describes the rotor’s regular operation was the only one included. The data is then used to predict the values of the rotor and then determine whether that prediction is sufficient. 

The inspection alarm is then triggered if the operation of the rotor predicts that it is out of regular functioning. Understanding these parts of data science is very important and can help you tap into the data science industry.

Deployment and optimization

Once data is being implemented in different systems, it is important to monitor it for a successful system. Above deploying data to the system you aimed for, you need to optimize it if it is not properly operational. It forms part of the testing process and is a valuable skill in data science. 

Set goals

Setting goals is a great way to make data science a priority in your life and it also helps you keep track of what you still need to learn. The reason behind your decision to pursue data science should always resonate in your mind and push you to learn more. 

Set goals around the reason why you started learning data science. If your goal was providing free data to disadvantaged people, the goals you set must be closely related to that.

Identify your skills

The first step to understanding data science is admitting that you will never know it all. It is easy to get lost in trying to understand all the models but that can be a futile effort. 

Identifying your most prominent skills and pursuing them is a very realistic method of truly understanding data science. Also, it is possible to build a machine learning model without studying the entire theory first.

Monthly roadmap

Above establishing goals, drafting a monthly roadmap will help you understand what you still need to learn. When using that roadmap and you have mastered or understood a particular skill, rating yourself will help very much. 

Each and every month, try to establish goals of the skills you will learn for that month. At the end of the month, give yourself a score and if it doesn’t impress, you include it again in the following monthly roadmap.

Don’t worry too much about completing MOOC’s

Some aspirant data scientists prefer completing all the MOOCs for them to believe they understand this industry. That isn’t true; this industry is one of those where you can learn concepts as the need arises. 

When trying data sets and coming across a certain concept you don’t understand, you can grab a certain part of a MOOC that addresses the problem you have. Don’t focus much on completing an entire MOOC but rather learn something you can practically do and apply.

Constantly compete

Data science competitions are a great way to benchmark performance in a particular machine learning practice. Some sites that offer the best competitions are kaggle.com and analyticsvidhya.com. The latter is more suited for beginners and always has open competitions with leader boards. 

Seeing your name on the top of the leader board can be really encouraging and help you progress. Above the encouragement, if you fail in a competition, you will realize where you went wrong and the next time you do it, the outcome will be impressive.

Don’t forget about soft skills

Data science isn’t all about technical skills only because you have to interact with other people that aren’t that technically prone. For example, you might need to explain a model to a colleague or present it to a board. In these cases, you need great communication skills, persistence, and resilience. 

Working on these soft skills will enable you to become a better data scientist and learner. The moral of the story here is to avoid falling into a technical rabbit hole so much that you forget connecting with other people within your profession.

White papers and workflow

Ensuring that you understand all the details of implementing data to a particular system is imperative. When using a system that already exists with your data input, download all the whitepapers and familiarize yourself with the workflow. Whitepapers are generally free to download, depending on the system you are working with.

Python fundamentals

To use Python for data science, you need to understand the basic fundamentals of this programming language. That will require you to take a brief course on Python or alternatively use online resources. There are a lot of free python introductory courses but one that comes highly recommended is CodeAcademy

The course provided by this website is very simple and practical because of its hand-on in-browser code editor that actively point out where you may be going wrong. The most important this to learn for data science is the syntax, functions, loops, control flow, classes, and modules.

Data analysis with Python

Understanding data analysis is the cornerstone of any career related to this industry. More especially, data scientists need to understand the process of analyzing data and those who already have an understanding need to improve their knowledge. 

One course that is also highly recommended is the data analyst learning path available on dataquest.io. The site has many other learning paths for data engineers, analysts and scientists and there a free parts of each of them. 

If you have some cash to invest in learning data science, analyzing and engineering, consider these learning paths. They are one of the best of their kind and offer comprehensive information that can be practically used.
