Tell me the three main course of data science and there overview ?
Data science is not a standalone course but a comprehensive major integrating various disciplines. It encompasses:
- Data Mining: Uncovering actionable insights from data.
- Big Data: Handling and analyzing massive datasets.
- Machine Learning: Utilizing algorithms to enable systems to learn and make predictions.
Linear Algebra
Understanding and manipulating matrices and vectors, fundamental to handling high-dimensional data.
Optimization
Techniques for optimizing models and algorithms to improve efficiency and performance in handling large datasets.
Dynamic Programming
A method for solving complex problems by breaking them down into simpler, overlapping subproblems, often used in optimization.
Hashing (LSH and Bloom Filter)
Utilizing hashing techniques, such as Locality-Sensitive Hashing (LSH) and Bloom filters, for efficient data storage and retrieval.
Streams and Concurrency
Concepts related to handling data streams and concurrent processing.
Small Data
Data that is small enough for human inference and accumulated slowly.
Big Data
Data generated in huge volumes and could be structured, semi-structured, or unstructured.

Data Collection
The process of collecting data as a result of a business problem.
Data Modeling
Creating a data model to make sense of the collected data and establish relationships.
Data Processing
Using tools like Apache Spark to process and analyze the modeled data.
Data Visualization
Presenting data in a graphical format to derive meaningful insights.
Internet of Things (IoT)
An interconnected network of smart devices that collect, analyze, and act upon data.
Single Node Architecture
Execution of algorithms on a single CPU, with direct data access from memory
Data Scaling
The ability of a system to handle an increasing amount of data, including storage scaling and computational scaling.

Type of Data
Different types of data, such as high-dimensional data, graph data, infinite data, and labeled data.
Descriptive Method
Finding human-interpretable patterns that describe the data.
Predictive Method
Using variables to predict unknown or future values of other variables.
Large-scale Computing
Dealing with machine failures and redundancy in storage infrastructure.
Distributed File System
A file system that enables clients to access file storage from multiple hosts through a computer network.
what is data mining
In the realm of data mining, various tasks contribute to the extraction of meaningful insights from vast datasets. For this course, our focus is on installing existing software and conducting analyses without delving deeply into database intricacies.
Data mining involves the extraction of substantial, Actionable Data
what is actionable data
Conclusive Meaning: The data leads to meaningful conclusions.
Relevance: The insights extracted are pertinent to the objectives at hand.
Consider actionable data as information that goes beyond raw figures. It leads to conclusions that hold significance. An example could be extracting insights that not only provide statistical information but also contribute to informed decision-making.
