An expert system is a computer system that uses knowledge and inference procedures to solve complex problems in a specific domain, similarly to a human expert. The document discusses an example of an automatic attendance system that uses RFID technology. It describes the basic components of an RFID-based attendance system, including an RFID reader, RFID cards, a microcontroller, keypad, buzzer, and LCD display. The microcontroller communicates with these components to read RFID tags, compare identities to a database, log attendance, and interface with a computer. When a valid RFID tag is detected, the student's attendance is logged, and an invalid tag triggers the buzzer.
An expert system is software that attempts to reproduce the performance of human experts in a specific domain. It consists of a knowledge base of facts and rules, a working storage to apply those rules to specific problems, and an inference engine that derives solutions. Expert systems are designed by knowledge engineers who work with domain experts to encode their expertise for problems such as consistent decision making. While expert systems provide standardized answers and never forget questions, they lack common sense, creativity, and can have errors or difficulties adapting to changes.
Artificial intelligence aims to create intelligent machines that work like humans through techniques like speech recognition and problem solving. Machine learning is a subset of AI where deep learning is a subset of machine learning that has significantly advanced AI. The main advantages of AI over natural intelligence are its fabulous speed, ability to operate 24/7 without tiring, and greater accuracy. However, natural intelligence has advantages of being more universal, able to multitask, perform complex movements, and be more creative. The key differences between AI and human intelligence are their nature of existence, how they are created, learning processes, dominance, and memory usage.
An expert system is an intelligent computer program that uses knowledge and inference procedures to solve problems that require significant human expertise. It emulates the decision-making ability of a human expert in a restricted problem domain. The basic concept of an expert system is that the user supplies facts to the system and receives expert advice in response. Internally, the expert system consists of a knowledge-base containing the expert knowledge and an inference engine that draws conclusions from the knowledge-base.
The document discusses expert systems, which are computer systems that emulate the decision-making ability of a human expert. It describes the typical architecture of an expert system, which includes a knowledge base, inference engine, user interface, explanation facility, and knowledge acquisition system.

An expert system is a computer-based system that uses knowledge from human experts to solve problems typically requiring an expert. Expert systems model the problem-solving abilities of human experts. They are well-suited for problems that do not require complex reasoning, are well-understood, use objectively described data, require fast and accurate answers, or where human expertise is difficult to obtain. Expert systems have three main modules: a knowledge acquisition module to obtain expertise from human experts, a consultation module to provide answers to user questions, and an explanation module to explain how answers are inferred.
An expert system is software that uses a knowledge base of human expertise to solve problems or clarify uncertainties in areas where human experts would normally need to be consulted. It captures knowledge from subject matter experts and represents it in a structured way so it can provide automated guidance or recommendations. Expert systems are used in many fields like medicine, engineering, science, and business to emulate the problem-solving abilities of human experts.

For three decades, many mathematical programming methods have been developed to solve optimization problems. However, until now, there has not been a single totally efficient and robust method to coverall optimization problems that arise in the different engineering fields.Most engineering application design problems involve the choice of design variable values that better describe the behaviour of a system.At the same time, those results should cover the requirements and specifications imposed by the norms for that system. This last condition leads to predicting what the entrance parameter values should be whose design results comply with the norms and also present good performance, which describes the inverse problem.Generally, in design problems the variables are discreet from the mathematical point of view. However, most mathematical optimization applications are focused and developed for continuous variables. Presently, there are many research articles about optimization methods; the typical ones are based on calculus,numerical methods, and random methods.
The calculus-based methods have been intensely studied and are subdivided in two main classes: 1) the direct search methods find a local maximum moving a function over the relative local gradient directions and 2) the indirect methods usually find the local ends solving a set of non-linear equations, resultant of equating the gradient from the object function to zero, i.e., by means of multidimensional generalization of the notion of the function’s extreme points from elementary calculus given smooth function without restrictions to find a possible maximum which is to be restricted to those points whose slope is zero in all directions. The real world has many discontinuities and noisy spaces, which is why it is not surprising that the methods depending upon the restrictive requirements of continuity and existence of a derivative, are unsuitable for all, but a very limited problem domain. A number of schemes have been applied in many forms and sizes. The idea is quite direct inside a finite search space or a discrete infinite search space, where the algorithms can locate the object function values in each space point one at a time. The simplicity of this kind of algorithm is very attractive when the numbers of possibilities are very small. Nevertheless, these outlines are often inefficient, since they do not complete the requirements of robustness in big or highly-dimensional spaces, making it quite a hard task to find the optimal values. Given the shortcomings of the calculus-based techniques and the numerical ones the random methods have increased their popularity.
In computer domain the professionals were limited in number but the numbers of institutions looking for
computer professionals were high. The aim of this study is developing self learning expert system which is
providing troubleshooting information about problems occurred in the computer system for the information
and communication technology technicians and computer users to solve problems effectively and efficiently
to utilize computer and computer related resources. Domain knowledge was acquired using semistructured
interview technique, observation and document analysis. Domain experts were purposively
selected for the interview question. The conceptual model of the expert system was designed by using a
decision tree structure which is easy to understand and interpret the causes involved in computer
troubleshooting. Based on the conceptual model, the expert system was developed by using ‘if – then’ rules.
The developed system used backward chaining to infer the rules and provide appropriate
recommendations. According to the system evaluators 83.6% of the users were satisfied with the prototype.
An expert system is a program that uses specialized knowledge to solve problems at a level similar to a human expert. It consists of a knowledge base that stores facts, rules and relationships about a problem domain. An inference engine applies reasoning techniques to the knowledge base to provide solutions, explanations and advice. Expert systems are used in a variety of fields including medicine, engineering and business to assist or replace human experts when their knowledge is needed but they are unavailable.
The document outlines applications of artificial intelligence including game playing, general problem solving, expert systems, natural language processing, computer vision, robotics, and education. It discusses each application in 1-3 paragraphs providing examples and components when relevant. The document concludes with references.
Ensemble learning uses multiple machine learning models to obtain better predictive performance than could be obtained from any of the constituent models alone. It involves techniques such as bagging and boosting. Bagging generates additional training data sets by sampling the original data with replacement and trains an ensemble of models on these data sets. Boosting trains models sequentially such that subsequent models focus on instances incorrectly predicted by preceding models, reducing errors. Both aim to reduce variance and improve predictive accuracy through model averaging or voting.
Association rule mining is an unsupervised learning technique used to discover relationships between variables in a large dataset. It analyzes how frequently items are purchased together and generates rules based on metrics like support, confidence and lift. For example, it can determine that customers who buy milk and diapers are likely to also purchase beer based on transaction histories. Association rule mining has applications in market basket analysis, medical diagnosis, catalog design and other domains.
The Bellman equation is used to calculate the value of states in reinforcement learning and dynamic programming. It defines the value of a state based on the expected rewards from being in that state plus the discounted value of the next state. The document provides an example of using the Bellman equation to calculate the value of different states in an environment by starting from the final state and working backwards. Key elements of the Bellman equation include the action, next state, reward, and discount factor for weighing future rewards.
Reinforcement learning in Machine learningMegha Sharma
The document discusses reinforcement learning, which is a machine learning technique where an agent learns from interacting with an environment. The agent performs actions and receives rewards or penalties as feedback to learn which actions yield the best outcomes. Specifically, it provides definitions of reinforcement learning, describes its key features like exploring an environment through trial-and-error, and discusses examples of positive and negative reinforcement. It also gives an example of an agent navigating a maze to reach a diamond reward while avoiding penalties. The agent learns which paths lead to rewards by trying different actions and remembering steps that were rewarded.
The EM algorithm is an iterative method used to find maximum likelihood estimates of parameters in statistical models where the data contains missing values or latent variables. It consists of an expectation step (E-step) where the missing data is estimated given the observed data and current estimates of the parameters, and a maximization step (M-step) where the parameters are estimated by maximizing the log-likelihood function, found using the estimates of missing data from the E-step. The algorithm repeats these two steps until the parameter estimates converge. The EM algorithm is commonly used for unsupervised learning techniques like clustering and can be applied to problems in computer vision, natural language processing, and healthcare. However, it converges slowly and may only find local optim
Entropy and information gain in decision tree.Megha Sharma
Entropy is a measure of unpredictability or impurity in a data set. It is used in decision trees to determine the best way to split data at each node. High entropy means low purity with an equal mix of classes, while low entropy means high purity with mostly one class. Information gain is the reduction in entropy when splitting on an attribute, with the attribute with the highest information gain chosen as the split. For example, in a data set on restaurant patrons, splitting on the "patrons" attribute results in a higher information gain than splitting on "type of food" so "patrons" would be chosen as the root node.
Types of Machine Learning. & Decision Tree.Megha Sharma
This document discusses different types of machine learning:
- Unsupervised learning finds patterns in unlabeled input data.
- Supervised learning uses labeled example data to learn a function that maps inputs to outputs. It is used for classification and regression problems.
- Reinforcement learning involves an agent learning from a series of rewards and punishments.
It then focuses on decision trees, a supervised learning technique used for classification. Decision trees represent a function that takes attribute values and returns an output. They use decision nodes and leaf nodes to split a dataset into subgroups to minimize the tree depth. The document provides an example of building a decision tree to classify restaurant wait times.
This document describes four branching structures used in decision making statements in programming:
1. If - Used to check a single condition and execute code if true.
2. If-else - Used to check a condition and execute one block of code if true and another if false.
3. Else-if ladder - Used to test multiple conditions in sequence, executing code for the first satisfied condition before exiting.
4. Nested if-else - Writing if statements inside other if statements to test complex nested conditions.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

5. History of
Expert System
The software program Dendral is considered the first
expert system because it automated the decision-
making process and problem-solving behavior of
organic chemists.
Its primary aim was to study hypothesis formation and
discovery in science. For that, a specific task in
science was chosen help organic chemists in
identifying unknown organic molecules, by analyzing
their mass spectra and using knowledge of chemistry.
It was done at Stanford University by Edward
Feigenbaum, Bruce G. Buchanan, Joshua Lederberg,
and Carl Djerassi, along with a team of highly creative
research associates and students.
It began in 1965 and spans approximately half the
history of AI research.

System
In artificial intelligence, an expert system is a
computer system emulating the decision-making
ability of a human expert.
Expert systems are designed to solve complex
problems by reasoning through bodies of
knowledge, represented mainly as if–then rules
rather than through conventional procedural
code.
The first expert systems were created in the
1970s and then proliferated in the 1980s.
