Linear regression in R for Data Scientists - Udemy

#artificialintelligence

The goal is to provide the student the computational knowledge necessary to work in the industry, and do applied research, using lineal modelling techniques. Some basic knowledge in statistics and R is recommended, but not necessary. The course has lots of code examples, real datasets, quizzes, and video. The video duration is 4 hours, but the user is expected to take at least 5 extra hours working on the examples, data, and code provided.


EXCLUSIVE - Artificial intelligence in government, education and healthcare - Current landscape and future potential

#artificialintelligence

Availability of massive volumes of data, relatively inexpensive computational capabilities and improved training techniques, such as deep learning, have led to significant leaps in AI capabilities and will only continue to do so for the foreseeable future. Prof. Cambria defined AI 1.0 as logic-based, symbolic (human-readable) AI, which involved creating a model of reality and creating ad-hoc rules in the form of if-then rules or search trees or ontologies (s a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist, used to limit complexity and to organise information). Philip Heah, Senior Director (Technology & Infrastructure Group), Infocomm Media Development Authority (IMDA) talked about exploring AI for data centre cooling. Sensors were placed in NSCC's data centres and unsupervised learning techniques (a type of machine learning algorithm used to draw inferences or find hidden patterns from datasets consisting of input data without labelled responses) were employed on the data.


New Draft Principles of AI Ethics Proposed by the Allen Institute for Artificial Intelligence and the Problem of Election Hijacking by Secret AIs Posing as Real People

#artificialintelligence

The latest draft principles come from Oren Etzioni, the CEO of the Allen Institute for Artificial Intelligence. Below is the new material about the Allen Institute's proposal that we added at the end of the AI-Ethics.com Oren Etzioni, a professor of Computer Science and CEO of the Allen Institute for Artificial Intelligence has created three draft principles of AI Ethics shown below. It involved a teacher at Georgia Tech named Jill Watson. Many humans are being fooled every day by bots posing as real people and creating fake news to manipulate real people.


The Definitive Q&A for Aspiring Data Scientists

@machinelearnbot

Those skills include machine learning (data mining), information retrieval, statistics, data and information visualization, databases (modeling, organizing, querying), data structures (including indexing schemes), programming (Python, R, SAS, Hadoop, Spark), graph/network analysis, natural language processing, optimization, and modeling & simulation. The degree programs come with a variety of emphases: Data Science, Data Analytics, Big Data Engineering, Business Analytics, Healthcare Analytics, Machine Learning, Statistics, Operations Research, Decision Sciences, Computational Science & Informatics, and a few more. There are also basic talents that are independent of specific software packages: statistical literacy, data literacy, computational literacy, machine learning algorithms, data wrangling, data cleaning, data storytelling, and subject matter expertise (in some discipline). Consequently, armed with these talents and aptitudes, the agile data scientist can learn and apply new software packages, can learn and apply new programming skills, and can learn and apply new approaches that are created by the brilliant analytic minds in numerous organizations (commercial, government, and academic).


Why Natural Language Processing is the Future of Business Intelligence - DZone Big Data

@machinelearnbot

The technology underpinning this revolution in human-computer relations is Natural Language Processing (NLP). But soon enough, you'll be able to ask your personal data chatbot about customer sentiment today and how they'll feel about your brand next week, all while walking down the street. Currently, NLP tends to be based on turning natural language into machine language. As Watson & Co. become more nuanced, NLP opens up the enormous troves of publicly available multimedia for mass analysis by machine, taking data that previously required a human eye to interpret and spitting out either quantitative answers, natural language answers, or both.


Driving Machine Learning Capability in Organization

@machinelearnbot

While many organizations have already adopted the machine learning for cost saving and revenue generation, there are still many organizations which have recently started. Any project should consists of a domain experts, business stakeholders, data engineers, and data scientists. One of the key issues is managers treating data scientists more like software engineers and developers than scientists. With fast paced developments in machine learning field like deep learning, increasing availability of data and computational power, the applications of machine learning will increase at rapid pace.


What Marketers Need to Know About Machine Learning

#artificialintelligence

With automated machine learning, we're starting to get a grasp on creating something like an automated data scientist to wrangle data, reduce dimensions, and get it into some kind of shape so that a human can then query it and gain some insights without having an entire data science department of two dozen people. We're even getting to the point with some unsupervised machine learning methods to parse out huge swaths of text to automatically generate things beyond, say, topic models or sentiment analysis. Like I mentioned earlier, we automate tasks across teams, like PR, business development, marketing, and sales, to have everyone's data communicating. While this is mostly a customer service function, marketing and PR teams most certainly should be paying attention to this.


The Future of Machine Learning Hardware – Hacker Noon

#artificialintelligence

Let's go through a high-level exploration of the evolution of computational hardware technologies with a focus on applications to machine learning (ML), and using cryptocurrency mining as an analogy. I posit that the machine learning industry is undergoing the same progression of hardware as cryptocurrency did years ago. Machine learning algorithms often consist of matrix (and tensor) operations. Each step in the hardware evolution provided orders of magnitude in performance improvement.


Mark Sagar Made a Baby in His Lab. Now It Plays the Piano

#artificialintelligence

At the University of Auckland, if you want to run hours upon hours of experiments on a baby trapped in a high chair, that's cool. When I visited the computer scientist's lab last year, BabyX was stuck inside a computer but could still see me sitting in front of the screen with her "father." Soul Machines wants to produce the first wave of likable, believable virtual assistants that work as customer service agents and breathe life into hunks of plastic such as Amazon.com's Companies with similar aspirations throughout Japan and the U.S. have produced a wide array of virtual avatars, assistants, and holograms. For a couple of years he used the creatures as the basis of a virtual assistant startup called Life F/X and had his faces read emails aloud.


A Beginners Guide to Natural Language Processing – Towards Data Science – Medium

#artificialintelligence

As I have begun my journey as a data scientist one of the most captivating is that which seeks to understand the meaning and influence of words, Natural Language Processing (NLP). It is primarily concerned with programming computers to accurately and quickly process large amounts of natural language corpora. While there are methods to attempt to understand changes in tone NLP continues to struggle with understanding things like sarcasm and detecting things like humor. CounterVectorization is a SciKitLearn library tool takes any mass of text and returns each unique word as a feature with the count of number of times that word occurs.
