What is the primary function of a "gateway" in IoT architecture?

• To control IoT devices remotely.

• To store and process IoT data locally.

• To connect IoT devices to the cloud.

• To act as a firewall for IoT traffic.

In the context of IoT (Internet of Things), which of the following statements is true regarding the general framework of IoT?

• IoT typically involves devices that only communicate with local servers.

• IoT framework is simpler than the representation in Equation 1.1

• IoT devices gather data but do not communicate it to central units.

• IoT is primarily used in a single application and not in enterprise processes.

What is the "edge" in edge computing in the context of IoT?

• The sharp outer edge of IoT devices.

• The part of a network that connects IoT devices to the internet.

• The cloud data center where IoT data is processed.

• The processing and storage done on IoT devices themselves, closer to the data source.

In IoT, what is the primary role of an "Embedded Operating System" like RIOT or Contiki?

 

• To run applications on cloud servers.

• To monitor network traffic.

• To manage firmware updates for IoT devices.

• To provide an operating system for IoT devices with resource constraints.

What does a "first-in first-out" (FIFO) manner refer to in the context of IoT devices?

• Message cache management

• Sensor calibration order

• Device message-queue behaviour

• IoT server prioritization

In deep reinforcement learning, what does the term "Q-Learning" refer to?

• A type of neural network architecture

• A technique for optimizing support vector machines

• A method for solving Markov decision processes

• A reinforcement learning algorithm for estimating the quality of actions

What is the purpose of a random variable in probability theory?

• To ensure that all outcomes of an experiment are numerical.

• To make experiments more uncertain and unpredictable.

• To model uncertainty and associate numerical values with experiment outcomes.

• To guarantee that all experiments have equally likely outcomes.

What is the primary objective of the Viterbi algorithm in the context of Hidden Markov Models (HMMs)?

• To estimate the parameters of an HMM from observed data.

• To calculate the most likely sequence of hidden states given observed data.

• To perform dimensionality reduction on HMM state vectors.

• To compute the transition probabilities between hidden states.

In reinforcement learning, what problem is the "credit assignment problem" related to?

• Selecting the best action for a given state

• Defining the reward function

• Determining how to explore the environment

• Allocating credit or blame for a sequence of actions

When applying dimensionality reduction techniques like Principal Component Analysis (PCA), what is a limitation to be aware of?

• It always improves the interpretability of the data.

• It requires the data to be linearly separable.

• It may lead to information loss.

• It only works for high-dimensional data.
