Which of the following best defines Artificial Intelligence?
- Ability of a machine to display human-like capabilities.
- Automated robots.
- Software that can improve its own code.
- The study of algorithms.
Artificial Intelligence (AI) refers to the simulation of human intelligence in machines, where they are programmed to think like humans and mimic their actions. This doesn't just mean automated robots, but any software that can process data, learn, and make decisions.
What is the basic function of chatbots in customer service?
- Generating weather forecasts.
- Creating 3D animations.
- Simulating human conversation to assist customers.
- Controlling hardware devices.
The basic function of chatbots in customer service is to simulate human conversation to assist customers. Chatbots are designed to answer customer inquiries, provide information, and perform tasks in a conversational manner, improving the efficiency of customer support operations.
How might federated learning be used to address privacy concerns in AI model training?
- By aggregating model updates on the local devices.
- By sharing user data with third parties.
- By training models on centralized servers.
- By utilizing public datasets.
Federated learning allows model training to occur on local devices, keeping user data decentralized and private. Model updates are aggregated without sharing raw data, thus addressing privacy concerns.
How does "Inverse Kinematics" contribute to robot control?
- It determines the joint angles required to achieve a desired end-effector position.
- It enhances visual recognition.
- It helps robots identify objects.
- It improves battery efficiency.
Inverse Kinematics is used in robot control to calculate the joint angles necessary to achieve a specific end-effector position and orientation. This is vital for controlling the movement and manipulation of robotic arms and limbs.
How can adversarial attacks pose a threat to AI models used in autonomous vehicles?
- They can cause AI models to make incorrect decisions, endangering safety.
- They can compromise the aesthetic design of vehicles.
- They can lead to vehicle system failures.
- They may result in minor passenger discomfort.
Adversarial attacks can pose a significant threat to AI models in autonomous vehicles by causing them to make incorrect decisions. These attacks manipulate input data to deceive AI models, potentially leading to safety hazards on the road.
How does dropout regularization work in neural networks?
- It increases the learning rate during training.
- It optimizes the weight initialization process.
- It randomly removes a fraction of neurons during each forward pass.
- It reduces the number of layers in the network.
Dropout regularization is a technique that randomly drops (sets to zero) a fraction of neurons during each forward pass. This helps prevent overfitting by forcing the network to learn more robust features. It doesn't affect the learning rate or layer count.
The _______ algorithm is used to optimize the weights in a neural network by minimizing the error in the output layer.
- Gradient Descent
- K-Means
- Principal Component Analysis
- Random Forest
Gradient Descent is the optimization algorithm commonly used to train neural networks. It minimizes the error (often measured by a loss function) in the output layer by iteratively adjusting the weights. This process helps the network learn and improve its predictions.
_______ learning allows model training on a decentralized network to enhance privacy and security.
- Federated
- Reinforcement
- Transfer
- Unsupervised
Federated learning is an approach that allows machine learning models to be trained across multiple decentralized devices or servers, preserving data privacy and security while still benefiting from collective learning.
What is a potential risk arising from non-standardized AI technologies in medical diagnosis systems?
- Faster patient care.
- Improved accuracy in diagnosis.
- Lower healthcare costs.
- Misdiagnosis and treatment errors.
Non-standardized AI technologies in medical diagnosis systems can pose a risk of misdiagnosis and treatment errors. Without standardization, AI systems might not provide consistent and reliable results, potentially harming patient health.
