Artificial Intelligence Questions (With Answers)

Get ready to tackle artificial intelligence questions with confidence. In this part, we provide examples of AI interview questions along with detailed answers. These questions cover a range of AI concepts, algorithms, and practical problem-solving scenarios. By going through these Q&A, you'll gain valuable insights into how to approach and respond to AI-related inquiries during your interview:


1) Explain the concept of transfer learning in the context of neural networks.

Answer: Transfer learning involves using pre-trained models on a large dataset to solve a similar problem with a smaller dataset. The idea is to transfer knowledge gained from solving one problem to another, saving computational resources and time.


2) What is the difference between supervised and unsupervised learning?

Answer: In supervised learning, the algorithm is trained on a labelled dataset, where each input is associated with a corresponding output. In unsupervised learning, the algorithm is given unlabeled data and must find patterns or structures on its own.


3) What is the vanishing gradient problem, and how does it affect deep neural networks?

Answer: The vanishing gradient problem occurs when gradients in the early layers of a deep neural network become extremely small during backpropagation. This can hinder the training of these layers as their weights are not updated effectively.


4) Explain the bias-variance tradeoff in machine learning.

Answer: The bias-variance tradeoff refers to the balance between bias (error from overly simplistic assumptions) and variance (error from too much complexity) in a model. A model with high bias may underfit, while a model with high variance may overfit.


5) What is the curse of dimensionality, and how does it affect machine learning algorithms?

Answer: The curse of dimensionality refers to the increased complexity and sparsity of data as the number of features or dimensions grows. It can lead to issues like increased computational requirements, overfitting, and difficulty in finding meaningful patterns.


6) Explain the difference between bagging and boosting.

Answer: Bagging (Bootstrap Aggregating) involves training multiple instances of the same learning algorithm on different subsets of the training data and averaging the results. Boosting, on the other hand, focuses on training multiple weak learners sequentially, with each learner correcting the errors of the previous one.


7) What is a convolutional neural network (CNN), and in what types of tasks are they commonly used?

Answer: CNNs are specialised neural networks designed for image processing, particularly for tasks like image classification and object detection. They use convolutional layers to automatically and adaptively learn spatial hierarchies of features from input images.


8) Explain the concept of L1 and L2 regularisation in machine learning.

Answer: L1 regularisation adds the absolute values of the coefficients as a penalty term to the cost function, encouraging sparsity. L2 regularisation adds the squared values of the coefficients, preventing large weights and promoting a more balanced model.


9) What is the difference between precision and recall?

Answer: Precision is the ratio of true positive predictions to the total number of positive predictions, while recall is the ratio of true positives to the total number of actual positives. Precision focuses on the accuracy of positive predictions, while recall emphasises capturing all actual positives.


10) Explain the concept of dropout in neural networks.

Answer: Dropout is a regularisation technique where randomly selected neurons are ignored during training. This helps prevent overfitting by ensuring that no single neuron becomes too specialised and overly dependent on certain input features.


11) What is the difference between stochastic gradient descent (SGD) and batch gradient descent?

Answer: In batch gradient descent, the entire dataset is used to compute the gradient of the cost function, while in stochastic gradient descent, only a single randomly selected data point is used for each iteration. Mini-batch gradient descent is a compromise, using a small subset (mini-batch) of the data.


12) Explain the working principle of a recurrent neural network (RNN).

Answer: RNNs are designed to work with sequences of data by maintaining a hidden state that captures information from previous time steps. This allows them to capture temporal dependencies and work well with tasks like time series prediction and natural language processing.


13) What is the difference between overfitting and underfitting?

Answer: Overfitting occurs when a model is too complex and fits the training data too closely, performing poorly on new, unseen data. Underfitting, on the other hand, happens when a model is too simple and fails to capture the underlying patterns in the data, also resulting in poor performance.


14) Explain the concept of one-shot learning.

Answer: One-shot learning refers to the ability of a model to learn from only a single example of each class. This is in contrast to traditional machine learning, which often requires large amounts of labelled data for effective training.


15) What are autoencoders, and what are their applications?

Answer: Autoencoders are neural network architectures designed for unsupervised learning. They consist of an encoder and a decoder, with the goal of learning a compressed representation of input data. Applications include data denoising, dimensionality reduction, and anomaly detection.


16) Explain the concept of attention mechanisms in deep learning.

Answer: Attention mechanisms allow neural networks to focus on specific parts of the input sequence when making predictions. This is particularly useful in tasks involving sequences, such as machine translation, where the model can selectively attend to relevant parts of the input.


17) What is the difference between a generative model and a discriminative model?

Answer: A generative model learns the probability distribution of the input data and can generate new samples, while a discriminative model focuses on learning the boundary between different classes and making predictions about which class a given input belongs to.


18) How does the K-nearest neighbours (KNN) algorithm work?

Answer: KNN makes predictions based on the majority class of the K-nearest neighbours to a given data point in the feature space. The choice of K and the distance metric are critical parameters in this algorithm.


19) Explain the concept of natural language processing (NLP) and its applications.

Answer: NLP involves the interaction between computers and human language. Applications include sentiment analysis, machine translation, named entity recognition, and chatbot development.


20) What is the Turing test, and why is it relevant to artificial intelligence?

Answer: The Turing test is a measure of a machine's ability to exhibit human-like intelligence. It involves a human judge interacting with both a machine and a human, without knowing which is which. If the judge cannot reliably distinguish between them based on their responses, the machine is considered to have passed the test.


21) How does a decision tree work, and what are its advantages and disadvantages?

Answer: A decision tree makes decisions by recursively splitting the dataset based on the most informative features. Its advantages include interpretability and ease of visualisation, but it can be prone to overfitting and may not handle complex relationships well.


22) Explain the concept of reinforcement learning.

Answer: Reinforcement learning involves training an agent to make sequential decisions by interacting with an environment. The agent receives feedback in the form of rewards or penalties, guiding it toward learning an optimal policy.


23) What is the difference between a shallow and a deep neural network?

Answer: Shallow neural networks have a small number of hidden layers, while deep neural networks have many hidden layers. Deep networks are capable of learning hierarchical representations of data, making them suitable for complex tasks.


24) How do you handle imbalanced datasets in machine learning?

Answer: Techniques for handling imbalanced datasets include resampling (oversampling minority class or undersampling majority class), using different evaluation metrics (precision-recall instead of accuracy), and employing algorithms that are robust to class imbalances.


25) Explain the concept of GANs (Generative Adversarial Networks).

Answer: GANs consist of a generator and a discriminator trained simultaneously in a competitive manner. The generator tries to generate realistic data, while the discriminator aims to distinguish between real and generated data. This adversarial training process leads to the generation of high-quality, realistic samples.
