Artificial Intelligence (AI) Interview Questions and Answers

What is Artificial Intelligence (AI)?

Artificial Intelligence (AI) is a field of computer science dedicated to creating systems that simulate human cognitive functions, such as reasoning, learning from data, and autonomous decision-making.

These systems can identify patterns, resolve challenging issues, and produce human-like material in a variety of fields by utilizing sophisticated algorithms and enormous datasets.

How does AI differ from machine learning and deep learning?

Machine learning is a subset of artificial intelligence (AI) that employs statistical methods to learn from data without explicit programming. Multi-layered neural networks are used in deep learning, a more specialized subset of machine learning, to automatically extract features and resolve extremely challenging problems like speech and image recognition.

What are the main types of AI (narrow AI, general AI, super AI)?

The following are the main types of AI:

What are the main types of AI (narrow AI, general AI, super AI)?

a) Artificial Narrow Intelligence (ANI): These systems, also referred to as "Weak AI," are made to carry out a particular, specific activity, such as online searching or facial recognition, and they are unable to function outside of their predetermined parameters.

b) Artificial General Intelligence (AGI): A hypothetical type of artificial intelligence that is capable of comprehending, learning, and applying its intelligence to every intellectual work that a human being can perform.

c) Artificial Super Intelligence (ASI): A future in which AI is more intelligent than humans in every aspect, including social skills, general knowledge, and scientific ingenuity.

What is machine learning?

In contrast to explicit, hard-coded instructions, machine learning, a subtype of artificial intelligence, allows systems to automatically learn from experience by seeing patterns in data.

When exposed to new, unseen data, these models can interpret information using a variety of techniques and provide incredibly accurate predictions or make decisions on their own.

What is the difference between supervised, unsupervised, and reinforcement learning?

Supervised learning uses labeled datasets to train models for specific outputs, whereas unsupervised learning identifies hidden patterns or clusters within unlabeled data. In contrast, reinforcement learning employs a trial-and-error methodology in which an agent gains the ability to make a series of decisions by being rewarded or penalized for its actions in a changing environment.

What is deep learning?

Deep learning is a specialized branch of machine learning that automatically extracts high-level features from vast volumes of unstructured data using multi-layered artificial neural networks.

What Is Deep Learning? Concepts, Examples, and Applications

Without the need for manual feature engineering, these models are able to tackle extremely complicated tasks like computer vision and natural language processing by simulating the way organic neurons process information.

What are neural networks?

Inspired by the organic structure of the human brain, neural networks are computer models made up of interconnected layers of "neurons" that process and transmit data. The network learns to identify intricate patterns and relationships in data to provide predictions or classifications by modifying the weights of these connections during training.

What is an artificial neuron?

The fundamental building element of a neural network is an artificial neuron, which is a mathematical function that takes in several inputs, ranks them according to relevance, and adds them all together.

This result is then passed through an activation function to determine the output, mimicking the way a biological neuron decides whether or not to "fire" a signal.

What is overfitting in machine learning?

When a machine learning model learns the noise and particular aspects of the training data too well, it becomes overfitted and performs very well on that data but is unable to generalize to new, unseen information.

In essence, the model gets overly complicated, much like a kid who memorizes all of the textbook questions but doesn't truly comprehend the material.

How can overfitting be prevented?

Regularization (L₁/L₂) and Dropout, which penalize excessive complexity, are two strategies used to prevent overfitting. Cross-validation is also used to make sure the model generalizes across various data subsets.

Additionally, by employing Early Stopping or increasing the amount of training data, the model is able to identify underlying patterns instead of memorizing particular noise.

What is underfitting?

When a machine learning model is underfit, it performs poorly on both the training set and fresh data because it is too basic to identify the underlying patterns in the data. Similar to a linear model attempting to map a complex, curved trend, it essentially indicates that the model has a significant "bias," failing to understand the relationship between features and the target variable.

What are a training dataset and a testing dataset?

A testing dataset is a distinct, unseen portion used to assess the model's ultimate performance and generalization, whereas a training dataset is the first collection of data used to teach a model how to recognize patterns and modify its internal parameters.

This distinction guarantees that the model is evaluated on its ability to resolve actual issues rather than on its ability to retain certain instances from its training phase.

What is feature engineering?

The process of leveraging domain expertise to choose, alter, or generate new input variables from unprocessed data in order to increase the predicted accuracy of a machine learning model is known as feature engineering.

It converts disorganized or complicated data into a format that makes it simpler for algorithms to find the underlying patterns needed to address a particular issue.

What is natural language processing (NLP)?

A subfield of artificial intelligence called natural language processing (NLP) gives computers the ability to comprehend, interpret, and produce spoken and written human language.

What is natural language processing NLP?

NLP powers technologies like virtual assistants and real-time translators by integrating computational linguistics with deep learning models to enable machines to interpret context, sentiment, and nuance.

What is computer vision?

A branch of artificial intelligence called computer vision makes it possible for computers to extract useful information from digital photos, movies, and other visual inputs. Deep learning and convolutional neural networks enable systems to recognize objects, monitor motion, and decipher complicated scenarios in order to automate operations such as autonomous driving and medical diagnostics.

What is reinforcement learning?

In reinforcement learning, an autonomous agent gains decision-making skills by acting in a way that maximizes a cumulative reward. The agent creates an ideal plan, or policy, for accomplishing difficult long-term objectives through a process of trial and error informed by input from its successes and failures.

What is the role of data in AI systems?

The following are the roles of data in AI systems:

a) Model Training: Machine learning models employ the instances and patterns found in data to modify their internal parameters and learn how to carry out particular tasks.

b) Accuracy and Performance: A model's ability to generalize to new circumstances is closely correlated with its volume and diversity of data; more representative data usually results in higher accuracy.

c) Feature Extraction: Data enables AI to recognize pertinent features that are required for classification and prediction, such as shapes in pictures or keywords in text.

d) Validation and Evaluation: To make sure the model has truly acquired the reasoning and not just memorized the training examples, it is tested using different sets of data.

e) Bias and Fairness: If the incoming data contains human biases, the AI would probably reproduce and magnify those biases in its outputs. The ethics of the system are determined by the quality of the data.

● Security and Adversarial Vulnerabilities: Artificial intelligence can be influenced by "adversarial attacks," which are deliberate, minute modifications to input data that are imperceptible to humans yet result in the AI producing confident but inaccurate predictions.

What is bias in AI systems?

When an algorithm generates consistently biased findings as a result of skewed or unrepresentative training data that reflects societal injustices or human preconceptions, this is known as bias in AI systems.

The model may result in unjust treatment or discrimination against particular groups in crucial sectors like hiring, financing, or law enforcement since it learns to mimic these preexisting trends.

How can AI models be evaluated?

Metrics like Accuracy, Precision, Recall, and F1-Score are used to assess how well AI models match real-world data. To depict performance trade-offs and make sure the model generalizes effectively to new, unseen data, methods like Confusion Matrices and ROC Curves are employed in addition to basic scores.
