The Data Science Process: 7 Key Steps in Analytics Application

Published

on

The Data Science Process

Suppose you are a business and you want to update your products. How would you know what to invest in and what the general market trends and demands are? This is where business analytics comes in. Business analytics, simply put, is a process of identifying trends and patterns through collected data to produce conclusions through interpretation and analysis.

It allows companies to use statistics and previous data interpretation to develop solutions for business activities and can be categorized into different types. The first two types—descriptive analytics and diagnostic analytics—deal with identification and discussion of the present: current market or problems. Predictive analytics or prescriptive analytics on the other hand produce more future-based results. They either predict the future trends or suggest pathways for companies for the future. The applications of business analytics are diverse; they can be used anywhere from stock marketing to customer relationship management.

While previously done manually, the new age of expansion and advancement has allowed the field of business analytics to evolve. Multiple new programming languages and processes including data science are now being used to improve efficiency. This advancing complexity is why companies often require specialists for business analytics.

Many ambitious data scientists and business analysts seek masters in business analytics jobs. They learn the art of business analytics and database building using data science. Business analytics relies on data science, but how does it work? What happens at the backend? How does some random unlinked data is used to contribute to the business growth?

According to this Data Scientist Course tutorial, Data science is a multistep process, and each step helps in applying analytics for the real-life performance enhancement of business models. Let’s place the process under the light and discuss it in detail to answer the questions mentioned above.

Understand the Goal

Data science is all about identifying the problems before solving them. Do you want to work on making more personalized recommendations for the consumers? Or do you want to cut down redundancies in your customer service process? The questions generated will help you understand the type of data you need to refine. The data required for customer interaction will be different from when you analyze the new product your company might be considering launching. Framing the question will help you have a streamlined approach for the next process.

Collect Required Data

Data exists on various platforms. The ocean of data needs fishing the required information out. Collecting data is like collecting ingredients for a recipe. You can’t make sweet baked results if you have no sugar in the form of data. Retrieving data requires knowledge and strong command of various technical tools, programs, and programming languages. You may need to search for data using web scraping. Another way is to use Web APIs and collect data through Facebook or Twitter. Moreover, you might have to directly obtain data from CSV (Comma Separated Value) files or TSV (Tab Separated Values) files. However, using the last option requires an understanding of the special Parser format.

Clean and Explore Data

Essentially this process requires converting your data into a useable format. If the data previously existed in states which could not work with programming languages such as Python, you will need to apply SQL on it. During this step, you will be filtering data out; after that comes the extraction and replacing of values. If you come across a non-value, you would need to replace it to complete your file. Cleaning your data is a literal process. You are extracting and saving the information you actually need while scrapping the rest. The end product should be homogenous data with complete columns.

When exploring data, you will also make questions to reach your main goal to develop insights.

Cleaning and exploring data are the longest processes of the data science journey. Collectively, they often consume 80% of the time of the project.

Modeling and Developing Your Database

Here, you will be mixing and merging multiple databases and then enriching them by combining multiple data sources and logs by considering the essential features. The feature of interest is often time-based, such as keeping track of date differences and highlighting any national holidays or festivals. Other features could include “name,” “age,” and “gender”. These features help identify the characteristics of the database and help in the machine learning process.

This process also uses modeling to use categorization within the same domain. For example, a distinction between inbox and spam could be made within the feature of received emails. For modeling purposes, a categorization of social and promotion can also be generated when studying a database related to emails.

While the data produced, collected, and manipulated represents the real world, it is essential to reduce the chances of biased interpretation. A data scientist or a business analyst has to keep a check to account for and interpret the machine learning model’s decisions.

Generate Visuals

Data visualization helps understand the trends easily. It highlights the information collected, and graphs enrich your database making it more communicable. You can understand your data in a better way before diving into the in-depth analysis. Not to mention, your boss could demand more transparency, and the visuals can help them understand the process better.

Analyze and Interpret Data

Now we are at the heart of the data science project. In this step, machine learning algorithms are deployed to produce insights that cannot be distinguished otherwise. Usually, unsupervised algorithms are used to derive trends by clustering groups of data—which often have decisive features —that show subtle trends. The analyzing part of the data science project is most commonly used to produce actionable insights. These trends are then used to actualize the predictive insights by the data scientists themselves. In advanced data science projects, supervised algorithms are put into action to produce future trends. In some cases, depending on the main goal set in step one, the predictive insights are replaced with prescriptive insights to prevent any negative results.

Communicate Your Findings

This step is mostly the displaying part, showcasing your findings to the stakeholders. While it is not a process of data science and analytics, it is the most important soft skill that allows your data science project to be put into use. The results are only effective if they are communicated efficiently: leaving an impact.

In the nutshell

Data science allows businesses to accelerate their growth against the competition by improving their business model. Since it is a complex process and requires multiple skills, a strong education background, such as a master’s in the concerned field, ensures high-quality application. The process involves retrieving data from online or shared databases and then trimming and cleaning the available information. The data is merged and formatted to gain some understanding of trends. These identified trends help narrow down and answer the questions that help a business achieve its objectives.

BLDC Motor Controller Design Principles

BLDC (Brushless DC) motors are widely used in various applications, from consumer electronics and appliances to automotive and industrial systems. To control the speed and direction of BLDC motors, specialized motor controllers are required. At Integra Sources, we specialize in designing custom BLDC motor controllers that meet the unique requirements of our clients’ applications.

What Is a BLDC Motor Controller?

A BLDC motor controller is an electronic device that controls the speed, direction, and torque of a BLDC motor. It consists of a microcontroller or digital signal processor (DSP) that generates the control signals for the motor’s power electronics, including the power transistors or MOSFETs. The BLDC motor controller also includes feedback sensors, such as Hall effect sensors or encoders, to provide feedback on the motor’s speed and position.

Key Design Principles of BLDC Motor Controllers

  1. Sensorless vs. Sensored Control: BLDC motor controllers can be classified into two main types: sensorless and sensored control. Sensorless control relies on the back electromotive force (EMF) of the motor to determine its speed and position, while sensored control uses external sensors, such as Hall effect sensors or encoders, to provide feedback. The choice between sensorless and sensored control depends on factors such as cost, complexity, and performance requirements.
  2. Commutation Techniques: BLDC motors require electronic commutation to control the timing of the motor’s winding currents. There are several commutation techniques used in BLDC motor controllers, including trapezoidal (six-step) commutation and sinusoidal (vector) commutation. Trapezoidal commutation is simpler and more cost-effective but may result in lower efficiency and torque ripple. Sinusoidal commutation provides smoother and more efficient motor operation but requires more complex control algorithms and hardware.
  3. Control Algorithms: The control algorithm used in a BLDC motor controller determines how the motor’s speed and torque are regulated. Common control algorithms include open-loop control, closed-loop speed control, and closed-loop position control. Open-loop control provides basic speed regulation but does not account for variations in load or motor parameters. Closed-loop control algorithms use feedback from sensors to adjust the motor’s speed and position in real time, providing precise control over the motor’s operation.
  4. PWM (Pulse-Width Modulation) Techniques: PWM is used to control the average voltage applied to the motor windings, thereby controlling bldc motors. There are several PWM techniques used in BLDC motor controllers, including six-step commutation PWM, sinusoidal PWM, and space vector modulation (SVM). These techniques vary in complexity and efficiency, with space vector modulation offering the highest level of control and efficiency.
  5. Overcurrent and Overtemperature Protection: BLDC motor controllers must include protection features to prevent damage to the motor and controller in the event of faults or overloads. Overcurrent protection limits the motor’s current to prevent overheating and damage to the motor windings. Overtemperature protection monitors the temperature of the motor and controller and reduces the motor’s power if it exceeds a safe threshold.
