Artificial intelligence (AI) is no longer the realm of science fiction. AI is quickly becoming a powerful new technology and is set to disrupt any sector that deals with large amounts of data, and education is no different. The academic world is still considered one of the most human sectors -- the most human of the humanities -- but that doesn't mean there aren't ways in which teachers and school workers can benefit from implementing artificial intelligence. Just like any other industry, teachers deal with a huge amount of admin, and they are often having to spread their finite time between an ever-growing student body. As a result, the quality and relevance of education is becoming difficult to maintain.

This research work deals with Natural Language Processing (NLP) and extraction of essential information in an explicit form. The most common among the information management strategies is Document Retrieval (DR) and Information Filtering. DR systems may work as combine harvesters, which bring back useful material from the vast fields of raw material. With large amount of potentially useful information in hand, an Information Extraction (IE) system can then transform the raw material by refining and reducing it to a germ of original text. A Document Retrieval system collects the relevant documents carrying the required information, from the repository of texts. An IE system then transforms them into information that is more readily digested and analyzed. It isolates relevant text fragments, extracts relevant information from the fragments, and then arranges together the targeted information in a coherent framework. The thesis presents a new approach for Word Sense Disambiguation using thesaurus. The illustrative examples supports the effectiveness of this approach for speedy and effective disambiguation. A Document Retrieval method, based on Fuzzy Logic has been described and its application is illustrated. A question-answering system describes the operation of information extraction from the retrieved text documents. The process of information extraction for answering a query is considerably simplified by using a Structured Description Language (SDL) which is based on cardinals of queries in the form of who, what, when, where and why. The thesis concludes with the presentation of a novel strategy based on Dempster-Shafer theory of evidential reasoning, for document retrieval and information extraction. This strategy permits relaxation of many limitations, which are inherent in Bayesian probabilistic approach.

So, you simply call these libraries and then run these algorithms.

Facial recognition is arguably the most talked-about technology within the artificial intelligence landscape due to its wide range of applications and biased outputs. Several countries are adopting this technology for surveillance purposes, most notably China and India. Both are among the first countries to make use of this technology on a large scale. Even the EU has pulled back from banning this technology for some years and has left it for the countries to decide. This will increase the demand for professionals who can develop solutions around facial recognition technology to simplify life and make operations efficient. Data science influencer Andrew Ng, along with teaching assistants from Stanford University, have devised a course that includes neural style transfer which enables working with facial images effectively.

Feature importance refers to techniques that assign a score to input features based on how useful they are at predicting a target variable. There are many types and sources of feature importance scores, although popular examples include statistical correlation scores, coefficients calculated as part of linear models, decision trees, and permutation importance scores. Feature importance scores play an important role in a predictive modeling project, including providing insight into the data, insight into the model, and the basis for dimensionality reduction and feature selection that can improve the efficiency and effectiveness of a predictive model on the problem. How to Calculate Feature Importance With Python Photo by Bonnie Moreland, some rights reserved. Feature importance refers to a class of techniques for assigning scores to input features to a predictive model that indicates the relative importance of each feature when making a prediction. Feature importance scores can be calculated for problems that involve predicting a numerical value, called regression, and those problems that involve predicting a class label, called classification.

Gradient boosting is a powerful ensemble machine learning algorithm. It's popular for structured predictive modeling problems, such as classification and regression on tabular data, and is often the main algorithm or one of the main algorithms used in winning solutions to machine learning competitions, like those on Kaggle. There are many implementations of gradient boosting available, including standard implementations in SciPy and efficient third-party libraries. Each uses a different interface and even different names for the algorithm. In this tutorial, you will discover how to use gradient boosting models for classification and regression in Python. Standardized code examples are provided for the four major implementations of gradient boosting in Python, ready for you to copy-paste and use in your own predictive modeling project.

Argmax is a mathematical function that you may encounter in applied machine learning. For example, you may see "argmax" or "arg max" used in a research paper used to describe an algorithm. You may also be instructed to use the argmax function in your algorithm implementation. This may be the first time that you encounter the argmax function and you may wonder what it is and how it works. In this tutorial, you will discover the argmax function and how it is used in machine learning.
