Artificial intelligence is a field of computer science and engineering focused on the creation of intelligent agents, which are systems that can reason, learn, and act autonomously. The five main areas of AI research are machine learning, natural language processing, robotics, planning and scheduling, and knowledge representation and reasoning.
Machine learning is a subfield of AI that deals with the design and development of algorithms that can learn from data. Machine learning algorithms are used to automatically extract patterns from data and make predictions about future events.
Natural language processing is another subfield of AI that deals with the understanding and manipulation of human language by computers. NLP algorithms are used for tasks such as automatic text summarization, machine translation, named entity recognition, part-of-speech tagging, sentiment analysis, etc.
Robotics is another area of AI research that deals with the design and control of robotic systems. Robotics algorithms are used for tasks such as path planning, navigation, object manipulation, etc.

Machine Learning
ML is a programming technique that provides computers with the ability to learn without being explicitly programmed.
In the 1950s, Arthur Samuel defined machine learning as a “field of study that gives computers the ability to learn without being explicitly programmed.” This definition is still widely used today.
Machine learning is a subset of artificial intelligence (AI) in which computers are trained to perform tasks by example, instead of being explicitly programmed to do so. Machine learning algorithms build computational models from data that can be used to make predictions or decisions without human intervention.
There are two main types of machine learning: supervised and unsupervised. Supervised learning algorithms are given training data that includes both input values and desired output values. The algorithm then learns how to map the input values to the output values so that it can make predictions for new data. Unsupervised learning algorithms are given only input values and must learn how to group or cluster the data into meaningful patterns on their own.
Machine learning is a powerful tool for solving many real-world problems, such as facial recognition, spam filtering, and medical diagnosis. However, there are also some potential risks associated with its use, such as biased results or automated decision-making with potentially harmful consequences.
Deep Learning
Deep learning allows computational models that are composed of multiple processing layers to learn representations of data with increasing levels of abstraction. The process starts with low-level features, such as pixel values for an image, and builds up through intermediate layers until a high-level representation is produced. For example, in image classification, the initial layers might learn about edges, shapes, and textures; the middle layers would learn about parts of objects; and the final layer would output whether or not there is an object in the image as a whole.
There are many different types of deep neural networks (DNNs), each with their own strengths and weaknesses for various tasks. The most popular DNNs include convolutional neural networks (CNNs) and recurrent neural networks (RNNs). CNNs are typically used for computer vision tasks, while RNNs are better suited for natural language processing tasks.
The main advantage of deep learning over other machine learning methods is its ability to automatically learn features from data without human intervention. This can be contrasted with shallow machine learning methods that require manual feature engineering by humans which can be time-consuming and expensive. In addition, deep learning models often have much higher accuracy than shallow models on complex tasks such as image classification and object detection.
However, deep learning also has some disadvantages compared to other machine learning methods. One issue is that it can be difficult to interpret what features a DNN has learned since the models can be very opaque/black box in nature. Another challenge is that DNNs require large amounts of training data in order to achieve good performance which can be impractical for many real-world applications.”
Natural Language Processing
NLP is used in many different applications such as automatic summarization, machine translation, named entity recognition, part-of-speech tagging, question answering, relationship extraction, sentiment analysis, speech recognition, and topic segmentation.
Some of the challenges in NLP include dealing with ambiguity and variability in human languages, developing computational models of human language acquisition and processing, and building systems that can effectively communicate with humans in natural language.
Computer Vision
Digital images can be acquired via various means such as digital cameras, scanners, or other imaging devices. Once acquired, they can be processed using a wide variety of algorithms to extract interesting features or patterns. Finally, the extracted information can be used for various tasks such as object recognition or classification, 3 d reconstruction, motion estimation or tracking, etc.
The area of computer vision has seen significant growth in recent years due to the increasing availability of powerful hardware (e.g., GPUs) and large datasets (e.g., ImageNet). In addition, advances in machine learning have made it possible to train complex models that are able to automatically learn rich feature representations from data.
One important application of computer vision is facial recognition which is used in a variety of settings such as security (e.g., unlocking your phone with your face), social media (tagging friends in photos), and marketing (targeting ads based on age/gender). Other popular applications include object detection (e.g., detecting pedestrians for autonomous driving), image search (finding similar images), and medical image analysis (detecting diseases).
