Supervised Learning

Supervised machine learning builds a model that makes predictions based on evidence in the presence of uncertainty. A supervised learning algorithm takes a known set of input data and known responses to the data (output) and trains a model to generate reasonable predictions for the response to new data. Use supervised learning if you have known data for the output you are trying to predict.

Supervised learning uses classification and regression techniques to develop predictive models.

Classification techniques predict discrete responsesfor example, whether an email is genuine or spam, or whether a tumor is cancerous or benign. Classification models classify input data into categories. Typical applications include medical imaging, speech recognition, and credit scoring.

Use classification if your data can be tagged, categorized, or separated into specific groups or classes. For example, applications for hand-writing recognition use classification to recognize letters and numbers. In image processing and computer vision, unsupervised pattern recognition techniques are used for object detection and image segmentation.

Common algorithms for performing classification include support vector machine (SVM), boosted and bagged decision trees, k-nearest neighbor, Nave Bayes, discriminant analysis, logistic regression, and neural networks.

Regression techniques predict continuous responsesfor example, changes in temperature or fluctuations in power demand. Typical applications include electricity load forecasting and algorithmic trading.

Use regression techniques if you are working with a data range or if the nature of your response is a real number, such as temperature or the time until failure for a piece of equipment.

Common regression algorithms include linear model, nonlinear model, regularization, stepwise regression, boosted and bagged decision trees, neural networks, and adaptive neuro-fuzzy learning.

Qubits and Defining the Quantum Computer | HowStuffWorks

September 5, 2019 | Author: admin

The Turing machine, developed by Alan Turing in the 1930s, is a theoretical device that consists of tape of unlimited length that is divided into little squares. Each square can either hold a symbol (1 or 0) or be left blank. A read-write device reads these symbols and blanks, which gives the machine its instructions to perform a certain program. Does this sound familiar? Well, in a quantum Turing machine, the difference is that the tape exists in a quantum state, as does the read-write head. This means that the symbols on the tape can be either 0 or 1 or a superposition of 0 and 1; in other words the symbols are both 0 and 1 (and all points in between) at the same time. While a normal Turing machine can only perform one calculation at a time, a quantum Turing machine can perform many calculations at once.

Today's computers, like a Turing machine, work by manipulating bits that exist in one of two states: a 0 or a 1. Quantum computers aren't limited to two states; they encode information as quantum bits, or qubits, which can exist in superposition. Qubits represent atoms, ions, photons or electrons and their respective control devices that are working together to act as computer memory and a processor. Because a quantum computer can contain these multiple states simultaneously, it has the potential to be millions of times more powerful than today's most powerful supercomputers.

This superposition of qubits is what gives quantum computers their inherent parallelism. According to physicist David Deutsch, this parallelism allows a quantum computer to work on a million computations at once, while your desktop PC works on one. A 30-qubit quantum computer would equal the processing power of a conventional computer that could run at 10 teraflops (trillions of floating-point operations per second). Today's typical desktop computers run at speeds measured in gigaflops (billions of floating-point operations per second).

Quantum computers also utilize another aspect of quantum mechanics known as entanglement. One problem with the idea of quantum computers is that if you try to look at the subatomic particles, you could bump them, and thereby change their value. If you look at a qubit in superposition to determine its value, the qubit will assume the value of either 0 or 1, but not both (effectively turning your spiffy quantum computer into a mundane digital computer). To make a practical quantum computer, scientists have to devise ways of making measurements indirectly to preserve the system's integrity. Entanglement provides a potential answer. In quantum physics, if you apply an outside force to two atoms, it can cause them to become entangled, and the second atom can take on the properties of the first atom. So if left alone, an atom will spin in all directions. The instant it is disturbed it chooses one spin, or one value; and at the same time, the second entangled atom will choose an opposite spin, or value. This allows scientists to know the value of the qubits without actually looking at them.

Next, we'll look at some recent advancements in the field of quantum computing.

How Encryption Works | HowStuffWorks

September 5, 2019 | Author: admin

When we use the Internet, we're not always just clicking around and passively taking in information, such as reading news articles or blog posts -- a great deal of our time online involves sending others our own information. Ordering something over the Internet, whether it's a book, a CD or anything else from an online vendor, or signing up for an online account, requires entering in a good deal of sensitive personal information. A typical transaction might include not only our names, e-mail addresses and physical address and phone number, but also passwords and personal identification numbers (PINs).

The incredible growth of the Internet has excited businesses and consumers alike with its promise of changing the way we live and work. It's extremely easy to buy and sell goods all over the world while sitting in front of a laptop. But security is a major concern on the Internet, especially when you're using it to send sensitive information between parties.

Let's face it, there's a whole lot of information that we don't want other people to see, such as:

Information security is provided on computers and over the Internet by a variety of methods. A simple but straightforward security method is to only keep sensitive information on removable storage media like portable flash memory drives or external hard drives. But the most popular forms of security all rely on encryption, the process of encoding information in such a way that only the person (or computer) with the key can decode it.

In this article, you will learn about encryption and authentication. You will also learn about public-key and symmetric-key systems, as well as hash algorithms.

How Quantum Computers Work | HowStuffWorks

September 5, 2019 | Author: admin

The massive amount of processing power generated by computer manufacturers has not yet been able to quench our thirst for speed and computing capacity. In 1947, American computer engineer Howard Aiken said that just six electronic digital computers would satisfy the computing needs of the United States. Others have made similar errant predictions about the amount of computing power that would support our growing technological needs. Of course, Aiken didn't count on the large amounts of data generated by scientific research, the proliferation of personal computers or the emergence of the Internet, which have only fueled our need for more, more and more computing power.

Will we ever have the amount of computing power we need or want? If, as Moore's Law states, the number of transistors on a microprocessor continues to double every 18 months, the year 2020 or 2030 will find the circuits on a microprocessor measured on an atomic scale. And the logical next step will be to create quantum computers, which will harness the power of atoms and molecules to perform memory and processing tasks. Quantum computers have the potential to perform certain calculations significantly faster than any silicon-based computer.

Scientists have already built basic quantum computers that can perform certain calculations; but a practical quantum computer is still years away. In this article, you'll learn what a quantum computer is and just what it'll be used for in the next era of computing.

You don't have to go back too far to find the origins of quantum computing. While computers have been around for the majority of the 20th century, quantum computing was first theorized less than 30 years ago, by a physicist at the Argonne National Laboratory. Paul Benioff is credited with first applying quantum theory to computers in 1981. Benioff theorized about creating a quantum Turing machine. Most digital computers, like the one you are using to read this article, are based on the Turing Theory. Learn what this is in the next section.

encryption – How secure is AES-256? – Cryptography Stack …

June 2, 2019 | Author: admin

An interesting thing about some modern standardized ciphers, like AES, is that the government is "eating its own dogfood" by using them internally. (AES 192 and 256 are approved for top-secret data.) Back in the day (up through the 90s), U.S. government internal encryption standards was not closely aligned with public sector cryptography, and we largely had to speculate as to whether public crypto could hold up to the government standards; the NSA had a history of knowing more crypto than they let on. But now that they are willing to stake their own security on them, that seems like a decent endorsement of those algorithms.

The U.S. government has conflicting goals: they want to be able to break crypto, but at the same time, in the interest of protecting the citizen in the digital age, they want us to be protected against the crypto attacks of others. So much of our modern economy relies on crypto that we want a high security margin on it. Since the 90s, crypto knowledge in the public and foreign intelligence domains has sky rocketed, and a vulnerability that the NSA can exploit is possibly a vulnerability that someone else can exploit. So at the drafting of AES, we doubt that they were focused on choosing a candidate that could be broken and kind of suspect they wanted a candidate that could not be.

Since you only break crypto when you don't have the key, to compromise those two goals they could just allow us mathematically secure crypto, then focus on getting the keys instead. If they can recover keys, they don't care how strong our crypto is. Attacking the endpoints that generate the keys is not always as hard as it seems (consider how many user and corporate machines get infected with malware, and think about what sort of key-related backdoors could be planted in popular software), and a simple subpoena might get keys in some situations. As more user data moves toward the cloud, backdoors in public services (voluntarily provided or not) are going to make the job of key recovery even easier.

Summary of these two points:

The federal government is allowed to use AES for top-secret information.

We don't know that they would actually want AES to be mathematically breakable, so at the AES competition 11 years ago it is possible they would have avoided any algorithm they thought they could break in the near future.

None of that is proof, but we tend to assume that the NSA can't break AES.

Quantum computing could change everything, and IBM is …

May 15, 2019 | Author: admin

In January, IBM made waves when it announced its IBM Q System One, the world's first gate model quantum computer available to businesses a system housed in a sleek, 9-cubic-foot glass case.

It's a major milestone for quantum computers, which had to date mostly been found in research labs. Already, IBM says, customers are lining up to figure out how to get their hands on this technology, which shows promise in fields as varied as chemistry, materials science, food production, aerospace, drug discovery, predicting the stock market and even fighting climate change.

The reason for excitement: a quantum computer has seemingly-magical properties that allow it to process exponentially more information than a conventional system. A quantum computer isn't just a much faster computer. Rather, it's an entirely different paradigm of computing that requires some radical rethinking.

Now, the race is on to be the first company to conquer the massive opportunity presented by this technology. IBM, Microsoft, Google, and other tech titans and startups alike are all placing big bets on the technology. Meanwhile, in December, the U.S. government passed the National Quantum Initiative Act, which proposes spending $1.2 billion over the next five years on labs, academia and companies to advance quantum computing technologies.

For a Split Second, a Quantum Computer Made History Go …

May 13, 2019 | Author: admin

The uncertainty principle, which lies at the heart of quantum mechanics, states that, at any given moment, either the location or the velocity of a subatomic particle can be specified, but not both. As a result, a particle such as an electron, or a system of them, is represented by a mathematical entity called a wave function, whose magnitude is a measure of the probability of finding a particle in a particular place or condition.

The wave function extends throughout space and time. The law describing its evolution, known as the Schrdinger equation, after Austrian physicist Erwin Schrdinger, is equally valid running forward or backward. But getting a wave function to go in reverse is no small trick.

Dr. Vinokur likened the challenge to sending a speeding billiard ball back to where it started. Seems easy: Just hit it with a cue stick. But if its a quantum ball, the uncertainty principle kicks in: You can know how hard to hit the ball, or in which direction to hit it, but not both.

Because of the uncertainty principle, the quantum ball will never return back to the point of the origin, Dr. Vinokur said.

Moreover, in quantum mechanics, the ball is actually a wave: Once its location is known, it spreads like ripples on a pond and evolves. Making it go backward takes more than a nudge with a cue stick. It requires reversing the phases of the waves, turning crests into troughs, and so forth, an operation too complex for nature to accomplish on its own.

Enter the quantum computer.

Unlike regular computers, which process a series of zeros and ones, or bits, quantum computers are made of so-called qubits, each of which can be zero and one at the same time. A quantum computer can perform thousands or millions of calculations simultaneously, so long as nobody looks to see what the answer is until the end.
