Practical Data Science Skills:

Writing SQL Queries & Building Data Pipelines

SQL (Structured SQL Query Language) is used to carry out various operations with the information stored in databases, such as changing records, deleting them as well as creating and altering tables and views as well as views. SQL can also be the default for all the modern big data platforms, which use SQL as their primary API for their relational database.

The data science process is a process that converts raw data into actionable responses to business queries. Data science pipelines streamline data transfer from source to destination, eventually giving you the insight to make business decisions.

Data Wrangling/Feature Engineering

Data Wrangling is the process of cleansing and unifying complicated and messy data sets to make them easier to access data and analysis. This usually involves manually changing and mapping the data from one format into another, allowing a more accessible and more efficient consumption and better data organization.

Feature engineering refers to the process of selecting, manipulating, and changing raw data into features that can be utilized to aid in supervising learning. In more straightforward phrases, Feature engineering is the act of converting raw data into features that are desired through machine learning or statistical methods.

GitHub

The area of Data Science has experienced tremendous growth in the past few years. Machine learning and data science are iterative ways to test new concepts. Git, along with GitHub, is an excellent tool to track the progress of your work and share information within your team and the company.

Storytelling

It is an effective method for delivering information tailored to an audience by using compelling stories. It’s the tenth foot of data analysis and is arguably the essential part. As evolutionary Humans, we are wired to share stories to share information.

Regression/Classification

In essence, classification is about predicting a label, while regression is the process of the prediction of a particular quantity. The classification problem is predicting a discrete class label output in a specific instance. Regression is the issue that predicts a continuous output in an instance.

Explanatory Models

The goal of an explanation model is to provide an explanation rather than predict the outcomes of death. In this case, the purpose of explanation is to use statistical inference to determine predictor variables that have statistically significant effects on the death event.

Explanatory models are a practical explanation of how something happens or an explanation for why a phenomenon occurs how it is. The model can be utilized as an alternative to “the complete description” of the item being discussed or because the complete explanation isn’t available.

A/B Testing (Experimentation)

A/B testing is an essential random control experiment. It’s a method to test two different versions of a given variable to determine the one that performs better in a controlled setting. You can employ random tests or apply techniques from statistical or scientific research. A/B testing is among the most crucial theories in data science and the world of technology generally because it’s among the top efficient methods of determining the validity of any possible hypothesis.

Clustering

Clustering is among the most popular forms in unsupervised or unsupervised training. It’s an excellent method for analyzing unlabeled data and dividing data into groups that are similar to each other. A sophisticated clustering algorithm can identify patterns and structures within a data set that is not obvious to the naked eye.

Data scientists and other researchers employ clustering to get valuable insights from data by studying the groupings (or clusters) the data points belong to when applying an algorithm for clustering the data. For example, clustering can be used to find groups of objects with similar characteristics in data sets that contain two or more variables.

Recommendation

Recommendation engines are data filtering tool that uses machine learning algorithms to suggest the most relevant products to the user or client. It works based on detecting patterns in customer behavior data that can be obtained either by implication or explicitly.

NLP

Natural Language Processing (NLP) is the science and art that allows us to extract information from texts and then create computations and algorithms. With the increase in information on the internet and social media, it’s an essential tool for all data scientists.

NLP involves using algorithms to detect and decode these natural language principles to convert unstructured language data into a format that computers can comprehend.

Explainable AI / Explainable Machine Learning in Data Science

It is possible to explain AI can explain the AI algorithm, its anticipated impact, and any biases that could be a possibility. It aids in assessing model accuracy, transparency, fairness, and the outcomes of AI-powered decision-making. It is easy to explain that AI is vital for any organization to establish trust and confidence before making AI model models.
