- In multi-class classification, accuracy is defined as follows: – – In binary classification, accuracy has the following definition: – – A function (for example, ReLU or sigmoid) that takes in the weighted sum of all of the inputs from the previous layer and then generates and passes an output value…
- The set of examples used in one iteration (that is, one gradient update) of model training.
- For example, a machine learning model that evaluates email messages and outputs either spam or not spam is a binary classifier.
- For example, in a binary classification model that detects spam, the two classes are spam and not spam.
- For example, here is a sample confusion matrix for a binary classification problem: – – The preceding confusion matrix shows that of the 19 samples that actually had tumors, the model correctly classified 18 as having tumors (18 true positives), and incorrectly classified 1 as not having a tumor (1…
- World Wi-Fi represents an exciting start-up, founded by the creators of Radius Wi-Fi and the Adrenta project, which aims to fix this issue, by granting people free internet access, through a decentralized Wi-Fi network that works by integrating residential routers.
- Guests will therefore be able to browse the Internet via the World Wi-Fi network, without having to pay anything.
- Router owners who wish to take part in the project, will create a dedicated Wi-Fi network, capable of generating passive income, by profiting from the ad sales made when other users are logged into the router.
- According to Yan Sepiashvili, a co-founder of the World Wi-Fi project, In the next three years, it is projected that at least 20 million Wi-Fi routers will be connected to the platform.
- As part of the effort to raise funds for the project, World Wi-Fi is holding an ICO, where investors, can purchase WeTokens, which can either be sold for a profit, or be used as payment for advertisement services.
- Graphic: Jim Cooke, Photo: Getty – Google has partnered with the United States Department of Defense to help the agency developartificial intelligence for analyzing drone footage, a move that set off a firestorm among employees of the technology giant when they learned of Googles involvement.
- Googles pilot project with the Defense Departments Project Maven, an effort to identify objects in drone footage, has not been previously reported, but it was discussed widely within the company last week when information about the project was shared on an internal mailing list, according to sources who asked not…
- Some Google employees were outraged that the company would offer resources to the military for surveillance technology involved in drone operations, sources said, while others argued that the project raised important ethical questions about the development and use of machine learning.
- To meet the aggressive timetable, the Defense Department partnered with AI experts in the tech industry and academia, working through Defense Information Unit Experimental, the departments tech incubation program, and the Defense Innovation Board, an advisory group created by former Secretary of Defense Ash Carter to bridge the technological gap…
- Key elements have to be put together and the only way to do that is with commercial partners alongside us. – A spokesperson for the Defense Department declined to say whether Google was its only private industry partner on Project Maven or to clarify Googles role in the project.
