What is Machine Learning? Machine Learning ML is a fascinating field of Artificial Intelligence AI research and practice where we investigate how computer agents can improve their perception, cognition, and action with experience. Machine Learning is about machines improving from data, knowledge, experience, and interaction.
Machine Learning utilizes a variety of techniques to intelligently handle large and complex amounts of information build upon foundations in many disciplines, including statistics, knowledge representation, planning and control, databases, causal inference, computer systems, machine vision, and natural language processing.
AI agents with their core at Machine Learning aim at interacting with humans in a variety of ways, including providing estimates on phenomena, making recommendations for decisions, and being instructed and corrected.
In our Machine Learning Department, we study and research the theoretical foundations of the field of Machine Learning, as well as on the contributions to the general intelligence of the field of Artificial Intelligence.
In addition to their theoretical education, all of our students, advised by faculty, get hands-on experience with complex real datasets. Machine Learning can impact many applications relying on all sorts of data, basically any data that is recorded in computers, University learning techniques as health data, scientific data, financial data, location data, weather data, energy data, etc.
As our society increasingly relies on digital data, Machine Learning is crucial for most of our current and future applications. Mitchell, Former Chair at the Machine Learning Department at Carnegie Mellon University provided a widely quoted, more formal definition of the algorithms studied in the machine learning field: This follows Alan Turing's proposal in his paper "Computing Machinery and Intelligence", in which the question "Can machines think?
In Turing's proposal the various characteristics that could be possessed by a thinking machine and the various implications in constructing one are exposed.
Machine learning is a field of computer science that often uses statistical techniques to give computers the ability to "learn" i. The name machine learning was coined in by Arthur Samuel. Evolved from the study of pattern recognition and computational learning theory in artificial intelligence, machine learning explores the study and construction of algorithms that can learn from and make predictions on data — such algorithms overcome following strictly static program instructions by making data-driven predictions or decisions, through building a model from sample inputs.
Machine learning is employed in a range of computing tasks where designing and programming explicit algorithms with good performance is difficult or infeasible; example applications include email filtering, detection of network intruders or malicious insiders working towards a data breach, optical character recognition OCRlearning to rank, and computer vision.
Machine learning is closely related to and often overlaps with computational statistics, which also focuses on prediction-making through the use of computers.
It has strong ties to mathematical optimization, which delivers methods, theory and application domains to the field. Machine learning is sometimes conflated with data mining, where the latter subfield focuses more on exploratory data analysis and is known as unsupervised learning.
Machine learning can also be unsupervised and be used to learn and establish baseline behavioral profiles for various entities and then used to find meaningful anomalies.
Within the field of data analytics, machine learning is a method used to devise complex models and algorithms that lend themselves to prediction; in commercial use, this is known as predictive analytics.
These analytical models allow researchers, data scientists, engineers, and analysts to "produce reliable, repeatable decisions and results" and uncover "hidden insights" through learning from historical relationships and trends in the data.
Machine learning tasks are typically classified into two broad categories, depending on whether there is a learning "signal" or "feedback" available to a learning system: The computer is presented with example inputs and their desired outputs, given by a "teacher", and the goal is to learn a general rule that maps inputs to outputs.
As special cases, the input signal can be only partially available, or restricted to special feedback: When used interactively, these can be presented to the user for labeling. No labels are given to the learning algorithm, leaving it on its own to find structure in its input.
Unsupervised learning can be a goal in itself discovering hidden patterns in data or a means towards an end feature learning. Another categorization of machine learning tasks arises when one considers the desired output of a machine-learned system: In classification, inputs are divided into two or more classes, and the learner must produce a model that assigns unseen inputs to one or more multi-label classification of these classes.
This is typically tackled in a supervised manner. Spam filtering is an example of classification, where the inputs are email or other messages and the classes are "spam" and "not spam". In regression, also a supervised problem, the outputs are continuous rather than discrete.
In clustering, a set of inputs is to be divided into groups.
Unlike in classification, the groups are not known beforehand, making this typically an unsupervised task. Density estimation finds the distribution of inputs in some space.
Dimensionality reduction simplifies inputs by mapping them into a lower-dimensional space. Topic modeling is a related problem, where a program is given a list of human language documents and is tasked with finding out which documents cover similar topics.
Among other categories of machine learning problems, learning to learn learns its own inductive bias based on previous experience. Developmental learning, elaborated for robot learning, generates its own sequences also called curriculum of learning situations to cumulatively acquire repertoires of novel skills through autonomous self-exploration and social interaction with human teachers and using guidance mechanisms such as active learning, maturation, motor synergies, and imitation.
