"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.

Introducing Bitfount

#artificialintelligence

Bitfount is a federated analytics and machine learning platform that makes extracting value from sensitive data easy, fast, private, and secure. For data custodians and data scientists or researchers partnering to achieve better insights from data, Bitfount combines the best of data collaboration design, with advanced privacy-preserving capabilities, while playing nicely with all of your existing tools and crucially not requiring the transfer of any raw data. Data collaboration today is a painful, messy business. As anyone who has attempted to set up a collaboration around sensitive data will know, the current process is generally very painful and slow. Valuable datasets languish in silos as a result of regulatory or commercial sensitivity concerns, incompatible data management solutions, lengthy contractual processes, or just plain lack of understanding of what data is available for which purposes within an organisation.


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.

Harnessing artificial intelligence to transform the employee experience

#artificialintelligence

Successful organizations have long known that their employees are their biggest asset, but recent job numbers show how hard organizations have to work to retain them. According to the U.S. Department of Labor's Job Openings and Labor Turnover Survey, the rate of quit levels remained significant at 4.2 million in December 2021 while job openings continued to be high at 10.9 million. This is a strong indication that the pandemic has turned the tables on the employer-employee dynamic. As lines between work and life have blurred for many – employees have started to reassess what's important to them and in turn, what they expect from their employers. Of course, salaries and benefits are still important, but they are considered table stakes.
