PyTorch in Python


First, let me start by explaining how PyTorch will become useful to you. PyTorch has many different uses but is primarily used as a replacement for NumPy to use the power of GPUs, as well as a deep learning research platform providing flexibility and speed. Artificial Intelligence is essentially the building of smart machines that are capable of performing tasks that normally require human intelligence. It encompasses machine learning as well as deep learning. Machine learning provides computer systems with the ability to learn and improve from experience but without having to be explicitly programmed, i.e., the development of computer programs that can access data and learn from it on their own.

AI's next big leap


A few years ago, scientists learned something remarkable about mallard ducklings. If one of the first things the ducklings see after birth is two objects that are similar, the ducklings will later follow new pairs of objects that are similar, too. Hatchlings shown two red spheres at birth will later show a preference for two spheres of the same color, even if they are blue, over two spheres that are each a different color. Somehow, the ducklings pick up and imprint on the idea of similarity, in this case the color of the objects. What the ducklings do so effortlessly turns out to be very hard for artificial intelligence. This is especially true of a branch of AI known as deep learning or deep neural networks, the technology powering the AI that defeated the world's Go champion Lee Sedol in 2016. Such deep nets can struggle to figure out simple abstract relations between objects and reason about them unless they study tens or even hundreds of thousands of examples.

Machine learning in detecting frequency-following responses


To improve the efficiency and timeliness in frequency-following response (FFR) testing, the purpose of this study was to investigate the capabilities of machine learning in the detection of FFRs. Continuous brain waves were recorded from 25 Chinese adults in response to a pre-recorded Mandarin monosyllable \yi2\ with a rising frequency contour. A total of 8000 artifact-free sweeps were recorded from each participant. Continuous brain waves sub-averaged from the first sweep up to the first 500 sweeps were considered FFR absent, whereas brain waves sub-averaged from the first sweep up to the last 1000 sweeps were considered FFR present. Six response features (Frequency Error, Slope Error, Tracking Accuracy, Spectral Amplitude, Pitch Strength and Root-Mean-Square Amplitude) were extracted from each recording and served as key predictors.

Human Component in Machine Learning


With automation becoming increasingly popular in the field of machine learning, one may wonder if the role of humans in machine learning will become non-essential at some point. When building a machine learning model, it's important to remember that the model must produce meaningful and interpretable results in real-life situations. This is where the human experience comes in. A human (qualified data science professional) has to examine the results produced by algorithms and computers to ensure that the results are consistent with real-world situations before recommending a model for deployment. With automation in machine learning, humans are still indispensable to make the connection between data, algorithms, and the real world.

Zapata raises $38 million for quantum machine learning


Zapata Computing has raised $38 million for its quantum computing enterprise software platform. The figure, which brings its total funding to over $64 million, will be put toward Zapata's core mission: "Delivering quantum advantage for customers through real business use cases." Quantum computing leverages qubits (unlike bits that can only be in a state of 0 or 1, qubits can also be in a superposition of the two) to perform computations that would be much more difficult, or simply not feasible, for a classical computer. Unlike most quantum computing startups that build the hardware, Zapata is focused on the algorithms and software that sit on top. Based in Boston, Zapata has one product: its hardware-agnostic Orquestra quantum computing platform.

Normal Distribution and Machine Learning


Normal Distribution is an important concept in statistics and the backbone of Machine Learning. A Data Scientist needs to know about Normal Distribution when they work with Linear Models(perform well if the data is normally distributed), Central Limit Theorem, and exploratory data analysis. As discovered by Carl Friedrich Gauss, Normal Distribution/Gaussian Distribution is a continuous probability distribution. It has a bell-shaped curve that is symmetrical from the mean point to both halves of the curve. A continuous random variable "x" is said to follow a normal distribution with parameter μ(mean) and σ(standard deviation), if it's probability density function is given by, This is also called a normal variate.

A Complete Neural Network Algorithm from Scratch in Python


The Neural Network has been developed to mimic a human brain. Though we are not there yet, neural networks are very efficient in machine learning. It was popular in the 1980s and 1990s. Recently it has become more popular. Probably because computers are fast enough to run a large neural network in a reasonable time.

Eureka: A family of computer scientists developed a blueprint for machine consciousness

CMU School of Computer Science

Renowned researchers Manuel Blum and Lenore Blum have devoted their entire lives to the study of computer science with a particular focus on consciousness. They've authored dozens of papers and taught for decades at prestigious Carnegie Mellon University. And, just recently, they published new research that could serve as a blueprint for developing and demonstrating machine consciousness. That paper, titled "A Theoretical Computer Science Perspective on Consciousness," may only a be a pre-print paper, but even if it crashes and burns at peer-review (it almost surely won't) it'll still hold an incredible distinction in the world of theoretical computer science. The Blum's are joined by a third collaborator, one Avrim Blum, their son.

YouTube's AI-generated video chapters could help you skip lengthy intros


YouTube chapters can help you quickly navigate a video, but you often don't have that luxury when creators have to add them by hand. There might not be as much of a rush going forward. The 9to5Google team reports that YouTube is testing automatic, AI-generated video chapters, A machine learning system creates the chapters by looking for text. In other words, a producer who's been thoughtful enough to title sections in the video itself might not have to add chapters later. The internet giant is currently experimenting with auto chapters for a "small group of videos," and is giving creators chances to opt out and offer feedback.

Can machines replace human workers? Ben-Gurion weighs in


This article is the second in a series on David Ben-Gurion's exchanges with Prof. Amos de-Shalit. A year and a half passed "quietly" since David Ben-Gurion and Prof. Amos de-Shalit last corresponded. During this time no letters or ideas were exchanged between the two. Nevertheless, the subject seems to have continued to preoccupy Ben-Gurion's thoughts, to the point where he began to read scientific articles by renowned physicists on related subjects. On June 10, 1959, Ben-Gurion decided to break his silence and sent de-Shalit a short and to-the-point letter.
