Five Reasoning Methods To Rule Them All.

#artificialintelligence

The five reasoning methods are also called the five tribes. They help to solve the Master Algorithm. Each of the five tribes has a different technique and strategy for solving problems that result in unique algorithms. If we are successful to combine these algorithms, then it will lead us to (theoretically) the master algorithm. These are defined by the Portugues author, Pedro Domingos in his book The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World.


Researchers Hid Malware Inside an AI's 'Neurons' And It Worked Scarily Well

#artificialintelligence

The authors concluded that a 178MB AlexNet model can have up to 36.9MB of malware embedded into its structure without being detected using a technique called steganography. Neural networks could be the next frontier for malware campaigns as they become more widely used, according to a new study. According to the study, which was posted to the arXiv preprint server on Monday, malware can be embedded directly into the artificial neurons that make up machine learning models in a way that keeps them from being detected. The neural network would even be able to continue performing its set tasks normally. "As neural networks become more widely used, this method will be universal in delivering malware in the future," the authors, from the University of the Chinese Academy of Sciences, write.


Dive into the neuron

#artificialintelligence

From the previous section (What is Neural Network), we learned that a neural network is a function, which is composed of neurons, and neuron is also a function. Among them, w1, …, wn, b are all parameters, and different linear functions have different parameters. When n 2, the function image is a hyperplane. Beyond 3D, visualization is not convenient. But you can imagine that its characteristic is straight.

First, the attacker needs to design the neural network. To ensure more malware can be embedded, the attacker can introduce more neurons. Then the attacker needs to train the network with the prepared dataset to get a well-performed model. If there are suitable well-trained models, the attacker can choose to use the existing models. After that, the attacker selects the best layer and embeds the malware. After embedding malware, the attacker needs to evaluate the model's performance to ensure the loss is acceptable. If the loss on the model is beyond an acceptable range, the attacker needs to retrain the model with the dataset to gain higher performance. Once the model is prepared, the attacker can publish it on public repositories or other places using methods like supply chain pollution, etc.


What is Machine Learning? A Primer for the Epidemiologist

#artificialintelligence

Machine learning is a branch of computer science that has the potential to transform epidemiologic sciences. Amid a growing focus on "Big Data," it offers epidemiologists new tools to tackle problems for which classical methods are not well-suited. In order to critically evaluate the value of integrating machine learning algorithms and existing methods, however, it is essential to address language and technical barriers between the two fields that can make it difficult for epidemiologists to read and assess machine learning studies. Here, we provide an overview of the concepts and terminology used in machine learning literature, which encompasses a diverse set of tools with goals ranging from prediction to classification to clustering. We provide a brief introduction to 5 common machine learning algorithms and 4 ensemble-based approaches. We then summarize epidemiologic applications of machine learning techniques in the published literature. We recommend approaches to incorporate machine learning in epidemiologic research and discuss opportunities and challenges for integrating machine learning and existing epidemiologic research methods. Machine learning is a branch of computer science that broadly aims to enable computers to "learn" without being directly programmed (1). It has origins in the artificial intelligence movement of the 1950s and emphasizes practical objectives and applications, particularly prediction and optimization. Computers "learn" in machine learning by improving their performance at tasks through "experience" (2, p. xv). In practice, "experience" usually means fitting to data; hence, there is not a clear boundary between machine learning and statistical approaches. Indeed, whether a given methodology is considered "machine learning" or "statistical" often reflects its history as much as genuine differences, and many algorithms (e.g., least absolute shrinkage and selection operator (LASSO), stepwise regression) may or may not be considered machine learning depending on who you ask. Still, despite methodological similarities, machine learning is philosophically and practically distinguishable. At the liberty of (considerable) oversimplification, machine learning generally emphasizes predictive accuracy over hypothesis-driven inference, usually focusing on large, high-dimensional (i.e., having many covariates) data sets (3, 4). Regardless of the precise distinction between approaches, in practice, machine learning offers epidemiologists important tools. In particular, a growing focus on "Big Data" emphasizes problems and data sets for which machine learning algorithms excel while more commonly used statistical approaches struggle. This primer provides a basic introduction to machine learning with the aim of providing readers a foundation for critically reading studies based on these methods and a jumping-off point for those interested in using machine learning techniques in epidemiologic research.


How to Implement Neural Networks with TensorFlow

#artificialintelligence

Students who have been concerned about data science and machine learning will often discuss deep learning and neural networks. If you are interested in deep learning but have not actually done it, you will learn from here. In this article, you will learn about TensorFlow and its practical role in neural networks and will try to solve real-life problems. Before reading this article, you need to know the basic knowledge of neural networks and some programming concepts. The code in the article is written using Python, so you also need to understand some of the basic syntaxes of Python in order to better understand the article. Neural networks, also known as simulated neural networks (SNNs), or artificial neural networks (ANNs) are a subset of machine learning.


What is Deep Learning and How Does it Work?

#artificialintelligence

At a very basic level, deep learning is a machine learning technique. It teaches a computer to filter inputs through layers to learn how to predict and classify information. Observations can be in the form of images, text, or sound. The inspiration for deep learning is the way that the human brain filters information. Its purpose is to mimic how the human brain works to create some real magic. In the human brain, there are about 100 billion neurons. Each neuron connects to about 100,000 of its neighbors.


How to Unlearn a Disease - Issue 103: Healthy Communication

My father, a neurologist, once had a patient who was tormented, in the most visceral sense, by a poem. Philip was 12 years old and a student at a prestigious boarding school in Princeton, New Jersey. One of his assignments was to recite Edgar Allan Poe's The Raven. By the day of the presentation, he had rehearsed the poem dozens of times and could recall it with ease. But this time, as he stood before his classmates, something strange happened.


Mushroom Classification Using Deep Learning

#artificialintelligence

Just by hearing the names of these dishes, people be drooling! Their flavor is one reason that takes the dish to the next level! But have you ever wondered if the mushroom you eat is healthy for you? From over 14,000 species of mushrooms in the world, how will you classify the mushroom as edible or poisonous? Poisonous mushrooms can be hard to identify in the wild!


Deep learning explained by example

#artificialintelligence

Deep learning is an advanced branch of machine learning that enables computers to solve complex problems from driving a car to successfully flying a helicopter without strictly learning from simulations. The two main branches of deep learning are computer vision and natural language processing. Deep learning is a combination of mathematics and Neurobiology, the artificial intelligence science aims to project the human learning process on computers so that computers could learn and improve from experience. As mentioned earlier artificial intelligence science is based on how we learn, deep learning is accomplished by imitating human brain architecture. Developing networks of connected processing units called "neurons".
