Which search strategy explores nodes level-by-level ensuring the discovery of the shortest path in an unweighted graph?
Depth-first search
Breadth-first search
Greedy best-first search
Simulated annealing
Breadth-first search systematically explores nodes level-by-level, ensuring that the shallowest, and thus shortest, path is found in an unweighted graph. This property makes it ideal for finding the optimal solution when all step costs are equal.
Which of the following knowledge representation methods uses interconnected nodes to represent concepts and their relationships?
Production system
Logic-based representation
Frame-based representation
Semantic network
Semantic networks depict concepts as nodes connected by edges that denote relationships between them. This graphical form is particularly intuitive for representing hierarchies and associative connections.
In supervised learning, what is the main objective?
To simulate cognitive behavior without using labels
To reduce the dimensionality of data
To discover hidden patterns in unlabeled data
To learn a mapping from inputs to outputs using labeled examples
Supervised learning involves training a model on a dataset with known input-output pairs so that it can predict outputs for new inputs accurately. The process relies on labeled examples to establish the correct mapping between features and targets.
Which task is a fundamental component of natural language understanding?
Image segmentation
Syntactic parsing
State estimation
Path planning
Syntactic parsing breaks down sentences to understand their grammatical structure, which is crucial in natural language understanding. It forms the basis for further semantic interpretation and processing of language data.
Which of the following is a key societal impact of the increasing use of AI in decision-making?
Bias in automated decision-making
Reducing computational memory requirements
Increasing robotic hardware efficiency
Optimizing algorithm speed
As AI systems are increasingly used in decision-making, the risk of biased outcomes becomes a major concern. Ensuring fairness and accountability in these systems is crucial to mitigate negative societal impacts.
Which aspect differentiates A* search from greedy best-first search?
A* search uses random sampling to decide which nodes to expand
A* search prioritizes the deepest nodes first during the search
A* search relies solely on the heuristic estimate without considering the path cost
A* search integrates both the actual path cost and a heuristic estimate, ensuring optimality with an admissible heuristic
A* search calculates the sum of the cost so far and a heuristic estimate to determine the best path, ensuring that it finds an optimal solution when the heuristic is admissible. In contrast, greedy best-first search only considers the heuristic value.
In logic-based inference, what does the resolution rule primarily assist with?
Parsing complex natural language sentences
Deriving new clauses by eliminating a complementary pair of literals
Ranking data based on probability distributions
Optimizing search strategies in large state spaces
The resolution rule is a fundamental inference mechanism in logic that derives new clauses by eliminating pairs of complementary literals. This method is widely utilized in automated theorem proving and logical reasoning systems.
Which of the following best describes the role of sensor fusion in robotics?
Synchronizing sensor outputs for aesthetic visualization
Combining data from multiple sensors to improve state estimation
Eliminating redundant sensor inputs to reduce processing time
Increasing data sampling rates by merging sensor streams
Sensor fusion involves integrating data from various sensors to obtain a more accurate and robust estimate of a robot's state. This method enhances the quality of perception and decision-making in dynamic environments.
In the context of neural networks, what is the purpose of a non-linear activation function?
It is primarily used to initialize network weights
It normalizes the input data across different layers
It reduces overfitting by limiting the magnitude of weights
It allows networks to model complex, non-linear relationships between inputs and outputs
Non-linear activation functions enable neural networks to capture and model complex, non-linear patterns in data. Without them, the network would only be able to learn linear mappings, greatly limiting its expressive power.
Which strategy is most commonly employed to reduce overfitting in machine learning models?
Reducing the training data to a minimal amount
Regularization techniques such as L1 or L2 regularization
Increasing the number of training epochs without modification
Using a larger hidden layer in neural networks
Regularization adds a penalty term to the loss function, discouraging overly complex models and thereby reducing the risk of overfitting. This approach helps models to generalize better to unseen data by keeping them simpler.
Which semantic model is particularly effective in capturing the contextual meanings of words in modern NLP applications?
Traditional statistical n-gram models
Bag-of-words models
Rule-based systems
Transformer-based models like BERT
Transformer-based models, such as BERT, utilize self-attention mechanisms to understand word context within sentences. This allows them to capture subtle language nuances that traditional models may miss.
In convolutional neural networks for computer vision, which layer is primarily responsible for extracting local features?
Recurrent layer
Convolutional layer
Pooling layer
Fully connected layer
The convolutional layer applies learnable filters over the input image to capture local spatial features. These filters allow the network to detect patterns, edges, and textures essential for computer vision tasks.
In robotic path planning, what distinguishes potential field methods from graph-based search algorithms?
Potential field methods guarantee a global optimum, unlike graph-based algorithms
Graph-based search algorithms make use of force fields to avoid obstacles
Potential field methods use continuous gradients based on attractive and repulsive forces, while graph-based methods discretize the environment
Graph-based methods rely on continuous spaces, while potential fields operate only on discrete maps
Potential field methods generate continuous forces that attract the robot toward goals and repel it from obstacles, operating over a continuous space. In contrast, graph-based search algorithms work with a discretized representation, which is a key distinction in their approaches.
Which ethical consideration is especially important when deploying AI systems in decision-making processes?
Ensuring transparency and accountability in algorithms
Prioritizing speed of execution over ethical review
Eliminating human oversight entirely
Maximizing computational efficiency regardless of complexity
Transparency and accountability ensure that AI systems can be scrutinized and trusted, especially when their decisions affect human lives. These considerations are vital to address biases and maintain ethical standards in automated processes.
Which of the following best describes the integration of machine learning with robotics?
It focuses primarily on hardware improvements rather than adaptive algorithms
It removes the need for sensor fusion in robotic systems
It enables robots to adapt to dynamic environments by learning from sensor data
It limits robots to pre-programmed behaviors, preventing adaptation
Integrating machine learning with robotics allows for adaptive behaviors by enabling robots to learn from real-time sensor data. This approach improves their ability to navigate and function in unpredictable, dynamic environments.
