Study Notes

Cognitive Computing

  • The Computational model should reflect “how” results were obtained, not just producing human-like behavior.
  • GPS (General Problem Solver) aims to produce a sequence of steps of the reasoning process similar to a person solving the same task.

Artificial Intelligence (AI)

  • The core components of AI are derived from logic, cognition, and computation, including knowledge, reasoning, search, natural language processing, and vision.
  • General AI aims to make a system that can think like a human by itself, but currently, no such system exists that can perform tasks as perfectly as a human.
  • Researchers are focused on developing machines with General AI, but it requires significant efforts and time.

Types of AI

  • Super AI: A hypothetical concept where machines surpass human intelligence, performing tasks better than humans with cognitive properties like thinking, reasoning, solving puzzles, making judgments, planning, learning, and communicating.
  • Type 1: Reactive Machines (e.g., IBM's Deep Blue, Google's AlphaGo) - purely reactive, do not store memories, and only focus on current scenarios.
  • Type 2: Limited Memory Machines (e.g., self-driving cars) - store past experiences or data for a short period, using stored data for a limited time.

Machine Learning and Deep Learning

  • Machine learning is a branch of science that deals with programming systems to automatically learn and improve with experience.
  • It is difficult to cater to all decisions based on all possible inputs, so algorithms are developed to build knowledge from specific data and past experience.

Embedded Systems

  • Embedded systems are used in various domains, including consumer electronics, home automation, telecommunications, automotive industries, healthcare, control and instrumentation, and banking applications.
  • Purpose of embedded systems: data collection, storage, representation, communication, processing, and monitoring performance.

Communication Protocols

  • Application Layer Protocols define how applications interface with lower layer protocols to send data over the network.
  • Examples of application layer protocols include HTTP, COAP, and others.
  • HTTP (Hypertext Transfer Protocol) forms the foundation of the World Wide Web, using a request-response model where clients send requests to servers using HTTP commands.
  • COAP (Constrained Application Protocol) is designed for machine-to-machine applications, running on top of UDP, and is used in constrained environments with constrained devices and networks.

Learn about the fundamentals of embedded systems, including System on Chip (SOC) and their applications in various domains such as consumer electronics, telecommunication, and healthcare.
