"Isolation Forest": The Anomaly Detection Algorithm Any Data Scientist Should Know

#artificialintelligence

"Isolation Forest" is a brilliant algorithm for anomaly detection born in 2009 (here is the original paper). It has since become very popular: it is also implemented in Scikit-learn (see the documentation). In this article, we will appreciate the beauty in the intuition behind this algorithm and understand how exactly it works under the hood, with the aid of some examples. Anomaly (or outlier) detection is the task of identifying data points that are "very strange" compared to the majority of observations. This is useful in a range of applications, from fault detection to discovery of financial frauds, from finding health issues to identifying unsatisfied customers. Moreover, it can also be beneficial for machine learning pipelines, since it has been proven that removing outliers leads to an increase in model accuracy.


The Future of Data Science and Machine Learning at Enterprise Scale - Qubole

#artificialintelligence

Data Science, Artificial Intelligence, Analytics, and Machine Learning at the Enterprise scale are terms you've probably heard before. But what do they mean? We break it down for you in this blog. So, What Is Data Science? Data Science is a series of disciplines, technology, skills, expertise, and knowledge that encompass one thing: obtaining and preparing data for analysis.


Top 10 AI LinkedIn Groups for Tech Enthusiasts in 2022

#artificialintelligence

Networking plays a critical role in one's professional life, particularly for people who depend on experts' opinions and hold curiosity about lived experiences.LinkedIn lets users connect to people of their choice, exchange ideas, or collaborate on projects. However, communicating directly with them comes at a price. Email messages for LinkedIn where users can message users directly is a premium feature. LinkedIn groups play a vital role in bringing together the tech enthusiasts to collaborate and brainstorm ideas; and it works particularly well in areas like artificial intelligence and machine learning, where you can get inputs from people who are experienced enough to instill a sense of direction and provide significant insights. It is a collaborative group of AI researchers who work on next-generation machine intelligence.


Technique protects privacy when making online recommendations

#artificialintelligence

Algorithms recommend products while we shop online or suggest songs we might like as we listen to music on streaming apps. These algorithms work by using personal information like our past purchases and browsing history to generate tailored recommendations. The sensitive nature of such data makes preserving privacy extremely important, but existing methods for solving this problem rely on heavy cryptographic tools requiring enormous amounts of computation and bandwidth. MIT researchers may have a better solution. They developed a privacy-preserving protocol that is so efficient it can run on a smartphone over a very slow network.

Big Data Exchange enters Indonesian data centre market with joint venture deal

ZDNet

Eileen Yu began covering the IT industry when Asynchronous Transfer Mode was still hip and e-commerce was the new buzzword. Currently an independent business technology journalist and content specialist based in Singapore, she has over 20 years of industry experience with various publications including ZDNet, IDG, and Singapore Press Holdings. Big Data Exchange (BDx) has marked its entry into Indonesia's data centre market through a joint venture agreement with PT Indosat and the latter's two subsidiaries. The move aims to tap increasing demand for cloud services and connectivity. Estimated to be worth $300 million, the deal would see BDx enter a conditional sale and purchase agreement of shares (CSPA) and establish a joint venture with PT Indosat, PT Aplikanusa Lintasarta, and PT Starone Mitra Telekomunikasi (SMT). Under the agreement, BDx, Indosat, and Lintasarta would set up data centre and cloud operations in the Asian market, BDx said in a statement Thursday.



Synergies raises $12M to give factory managers an AI analytics assistant – TechCrunch

#artificialintelligence

There's no lack of startups around the world trying to make industrial activities more efficient with artificial intelligence. Some invent robots to assist or replace manual labor, while others use machine learning to help businesses discover insights. Synergies Intelligent Systems falls into the second category. Michael Chang founded Synergies in 2016 in Boston to provide easy-to-use AI-powered analytics tools to medium-sized manufacturers. Having worked at Foxconn in Shenzhen in the late 2000s helping the Apple supplier improve yield rate, or reduce the percentage of defective products, using data analysis, Chang realized that not every factory has the financial prowess to spend tens of thousands of dollars on digitization.


Intelligent AI-Empowered Metasurface Could Revolutionize Our Lives

#artificialintelligence

The intelligent metasurface, AI-empowered artificial material, is a smart platform enabling various functions such as data mining, communication, energy harvest, and sensing by directly processing illuminated information-carrying waves on the physical level. The manipulation of electromagnetic waves and information has become an important part of our everyday lives. Intelligent metasurfaces have emerged as smart platforms for automating the control of wave-information-matter interactions without manual intervention. They evolved from engineered composite materials, including metamaterials and metasurfaces. As a society, we have seen significant progress in the development of metamaterials and metasurfaces of various forms and properties.
