Core Concepts: Here, we dive into the essential building blocks. Questions cover connectivity protocols (MQTT, CoAP), data ingestion workflows, and the differences between cloud-centric and edge-centric architectures.

Intermediate Concepts: This module focuses on the "intelligence" aspect. You will face questions regarding model selection for edge devices, including lightweight architectures like MobileNet and SqueezeNet.

Advanced Concepts: Learn to navigate the complexities of hardware acceleration. This section covers model optimization techniques such as pruning, quantization, and knowledge distillation, along with deep dives into TPU and FPGA utilization.

Real-world Scenarios: Apply your knowledge to industry use cases. You will solve problems related to predictive maintenance, smart retail, and autonomous drone navigation, focusing on balancing accuracy with resource constraints.

Mixed Revision / Final Test: A comprehensive, timed mock exam that pulls from all previous sections to test your stamina and holistic understanding of AI Edge and IoT AI Systems.

Option 2: Integer Quantization (INT8)

Option 3: Switching from ReLU to Sigmoid activation

Option 4: Increasing the input image resolution

Option 5: Using Batch Normalization during inference

Correct Answer: Option 2

Correct Answer Explanation: Integer Quantization converts 32-bit floating-point weights and activations to 8-bit integers. This significantly reduces the model size and speeds up inference on hardware that supports integer arithmetic.

Wrong Answers Explanation: * Option 1: Increasing layers adds more parameters, which increases memory usage.

Option 4: Increasing resolution requires more memory for feature maps during processing.

Option 5: Batch Normalization is usually folded into the weights during inference and does not reduce the model size on its own.

Option 2: To ensure high latency

Option 3: To eliminate the need for any sensors

Option 4: To minimize latency and ensure real-time response

Option 5: To make the system dependent on public Wi-Fi

Correct Answer: Option 4

Correct Answer Explanation: Safety-critical applications require immediate action. Edge processing removes the need for a round-trip to the cloud, ensuring responses are fast enough to prevent accidents.

Wrong Answers Explanation:

Option 2: The goal is to decrease latency, not increase it.

Option 3: Sensors are still required to gather data at the edge.

Option 5: Edge computing actually allows for offline operation, reducing dependency on external networks.

Option 2: To provide a lightweight messaging transport for low-bandwidth devices

Option 3: To replace the operating system of the edge device

Option 4: To encrypt hard drives on the server

Option 5: To render 3D graphics on a web browser

Correct Answer: Option 2

Correct Answer Explanation: MQTT is a publish-subscribe protocol designed for low-power, high-latency, or unreliable networks, making it ideal for connecting IoT sensors to gateways.

Wrong Answers Explanation:

Option 3: MQTT is an application layer protocol, not an operating system.

Option 4: Security is a feature, but the primary purpose is communication, not disk encryption.

Option 5: Rendering graphics is handled by GPUs and specialized libraries, not messaging protocols.
