data science vs machine learning
Data science and machine learning normally belong to the same domain, which is connected to applications and meaning.
What is Data Science?
Data science is evolved as a broad field that is promising and offers in-demand career paths. It is known to study data systems and processes, focusing on maintaining different data sets and further deriving meaning. Most of the successful data professionals are skilled and knowledgeable about analyzing large data, programming skills, and data mining.
The data scientists make use of a combination of tools, principles, applications, and algorithms. Nowadays, many organizations are busy generating an exponential amount of data, which is quite challenging to monitor. Simply, it is a science of emphasizing on data modeling and data warehousing for tracking data set whatever information that is extracted is further used for guiding business processes and attain the organizational goals.
Skills required for becoming a Data Scientist?
Most of the organizations have acknowledged the importance of data science required for data-driven decision making. The data scientists get jobs in three domains, depending on their skills.
- Mathematical/statistical reasoning
- Business communication leadership
Therefore, we are discussing the skills required for becoming a data scientist.
As defined, data scientist is a study of collecting, analyzing, presenting, interpretation, and organizing the data. Hence, there is no surprise that data scientists should know about the statistics.
- The programming language R/Python
The programming language is ideal for manipulating the data and applies the algorithms. Data scientists generally use Python and R because they are available for scientific and numeric computing.
- Loading, data extraction, and transformation
Generally, the data scientists have to collect information from different sources like MongoDB, Google Analytics, MySQL, and others. Such information is then converted for storing in the required format or structure for different purposes of analysis. Finally, the data is load in Data Warehouse for further analysis.
- Data exploration and wrangling
There are complete chances that data can be inconsistent. Thus, it is required to clean and unify the messy data sets for hassle-free access and termed as Data Wrangling Exploratory Data Analysis (EDA). With data science, it is possible to manipulate the data for best use.
- Machine learning
Machine learning is described as a process of making machines intelligent and instilled with the power of thinking, making decisions, and analyzing the data. With the precise Machine Learning models, a company can get the chance to identify the opportunities and cut down the risks. Data scientists should know about this technology and have good hands-on knowledge.
- Big data processing frameworks
A large portion of data is always needed to train Machine Learning or Deep Learning models. But, due to a lack of data or computational power, it is impossible to create accurate Machine Learning models.
Presently, the data is generated at an excellent velocity and available in a structured or unstructured form. Hence, it becomes difficult to process the data using traditional data processing systems. At this point, frameworks such as Spark and Hadoop are essential for handling big data.
- Data visualization
We all have heard about data visualization, which acts as a significant part of data analysis. This is obligatory for presenting the data understandably and presenting it in a visually appealing format. Data visualization is present as a skill used by data scientists for mastering for making communication better with the end-users.
These are some of the skills that every data scientist should be expertise in for successfully doing their work.
What is Machine Learning?
As defined above, it is an application of Artificial Intelligence that make machines learn and improve themselves automatically. It pays attention to the development of computer programs for accessing the data. Moreover, the procedure generally starts with data or observations like direct experience or instructions. Hence, by looking at the patterns in data, it is easy to make better decisions. The prime objective of this technology is allowing the computers to learn things automatically without any human interference.
In simple words, it is a unique approach relying on semantic analysis that mimics human ability to understand the meaning of the text. Machine learning algorithms typically use statistics for finding the patterns and encompass different things like images, numbers, clicks, and words. Many of the services like Netflix, Spotify, YouTube, and others nowadays are powered by Machine Learning. It collects the information as much as possible regarding genre people are watching, links they are visiting, and others. Honestly, this process includes searching for a pattern and applying the same.
Skills required becoming a machine learning expert
To begin with, if someone is going to make a career in Machine Learning, he or she should keep two aspects in mind. First, Machine Learning is not purely about the academic role. Secondly, it is not required to have a software engineer and data science experience. Here, we are discussing some important skills that one should emphasize on.
- Computer science programming and fundamentals
Computer science fundamentals are essential for Machine Learning engineers as it involves data structures (stacks, trees, graphs, etc.), algorithms (optimization, dynamic programming, searching and others), computability and complexity (approximate algorithms, big-O notation, etc.). Thus, one should know how to apply, adapt, implement, or address them while programming.
- Statistics and Probability
Presently, there are different means required for dealing with different uncertainty in the present world. Statistics is used for providing countless measures, distributions, and analysis methods that are needed for validating and building models from observed data. The algorithms related to Machine Leaning are present as extensions of statistical modeling procedures.
- Data evaluation and modeling
Data modeling is defined as the procedure for estimating the fundamental structure of a given dataset with the objective of finding useful patterns.
- Applying Machine Learning Algorithms and Libraries
Applying the Machine Learning algorithms involves a suitable model as a learning procedure to get fit into the data. Apart from this, be aware of the relative pros and cons of different approaches.
- System design and software engineering
The output of a Machine learning engineer is mentioned as software only that is present as a small component which gets fits into a larger ecosystem of services as well as products. System design is necessary for avoiding bottlenecks and helpful in increasing the volumes of data.
Scope of Data Science
Becoming a data scientist is the hottest trend going nowadays. Presently, data science is influenced by business intelligence. Being a data scientist, you have to deal with loads of data to analyze patterns, trends, and others. A business intelligence expert picks up from where data scientists leave, like using reports for understanding the latest data trends going in a particular business field and further providing business forecasts.
Data scientists are responsible for analyzing historical data as per different requirements while applying various formats such as:
- Predictive casual analytics
This model is used for deriving business forecasts. As the name suggests, it depicts the outcomes of different business actions.
- Prescriptive analysis
It is highly useful for businesses to set their goals by proposing the actions. This model makes use of interferences from the predictive model.
