Study Notes

Artificial Intelligence (AI) and Machine Learning (ML)

AI involves machines that can perform tasks characteristic of human intelligence.
Machine Learning (ML) is a way to achieve AI by "training" algorithms to learn from huge amounts of data.
Deep Learning (DL) is an approach to ML, inspired by the brain's structure and function.
Artificial Neural Networks (ANNs) mimic the biological structure of the brain.

Database Management for Data Science

Data refers to individual facts, statistics, or items of information, often numeric.
A database is a structured set of data held in a computer's memory or on the cloud.
Database Management Systems (DBMS) optimize and manage data storage and retrieval.

Types of Databases

Relational databases focus on relationships between stored data elements.
Examples of relational databases include Microsoft SQL Server, Oracle, MySQL, and IBM DB2.
NoSQL databases store data differently than relational tables, with types including:
- Document databases (e.g., MongoDB)
- Key-value databases
- Wide-column databases
- Graph databases

Big Data Analytics

Big Data refers to massive amounts of data that cannot be stored, processed, or analyzed using traditional tools.
Big data analytics uses advanced techniques against large, diverse data sets, including structured, semi-structured, and unstructured data.
Tools used in big data analytics include Hadoop, MongoDB, Talend, Cassandra, Spark, STORM, and Kafka.

Internet of Things (IoT)

The Internet of Things (IoT) describes physical objects embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks.
IoT is an evolution of mobile, home, and embedded applications interconnected to each other.
Examples of IoT include adjusting lighting and controlling devices remotely using mobile devices.

IoT Architecture

The four stages of IoT Architecture are:
1. Sensors and actuators – Sensing layer for Data Gathering
2. Internet gateways and Data Acquisition Systems – Network layer for Data Transmission
3. (not specified in the text)
