7 Things you should know about ROC AUC

  • Most of the material presented here is based on a paper by [Lobo et al.,2008] where the authors illustrate several issues regarding the usage of ROC AUC to evaluate the performance of classification models.
  • When the AUC is calculated, both false and true positive rates are equally weighted, and therefore it cannot help us select the model which fits our specific use case.
  • If minimizing the false-positive rate is the most important measure in our case, then model B is preferable to A, even though they have a very similar AUC.
  • In both cases we obtain the same AUC , but the change in other measurements (e.g., F1-score) show that our model’s performance varies according to the proportion of positive examples, while AUC is invariant under the above conditions — multiplying the negative and positive rows by different scalars [Sokolova & Lapalme, 2009].

Build an Angular 8 App with REST API and ASP.NET Core 2.2 - part 2

  • When we add components in the Node.js command prompt, the app.modules.ts file is updated as well.
  • The simplest thing to do is to just use Visual Studio to build and run our Angular app as well as the back-end.
  • Whether you want to use the Node.js command prompt to build and run the Angular application is up to you.
  • You can press F5 in Visual Studio 2019 or use the Node.js command prompt and ng serve to launch the app.
  • As it’s a single blog post we want to show, we fetch the id key from the url querystring with the built in ActivatedRoute component, and pass it to the service getBlogPost() method.
  • Depending on if we’re creating a new blog post or editing an existing one, we use actionType to show the correct form view with or without data.

Axios or fetch(): Which should you use?

  • The fetch() API is perfectly capable of reproducing the key features of Axios, and it has the added advantage of being readily available in all modern browsers.
  • Hopefully, by the end of the article, you’ll have a better understanding of both APIs. Before we delve into more advanced features of Axios, let’s compare its basic syntax to fetch().
  • One of the key features of Axios is its ability to intercept HTTP requests.
  • Axios provides an easy-to-use API in a compact package for most of your HTTP communication needs.
  • As discussed in this article, it’s perfectly possible to reproduce the key features of the Axios library using the fetch() method provided by web browsers.
  • In addition to logging Redux actions and state, LogRocket records console logs, JavaScript errors, stacktraces, network requests/responses with headers + bodies, browser metadata, and custom logs.

66% of Europe Refuse to Use Calibra for Libra Transfers – CCN.com

  • The results of a cryptocurrency survey conducted by the Dutch banking group, ING, revealed a significant lack of appetite for Facebook's Libra, and its designated use case: Sending payments across social media.
  • Turkey also cited a considerable level of support for cryptocurrency in general with 62% of the country positive about the future of digital payments, nearly doubling the sentiment presented by U.S. respondents.
  • Given we see higher trust in the technologies people are more familiar with, and a relative openness towards the idea of banks offering current accounts in cryptocurrencies (27% agree, 33% on the fence), a digital currency hybrid which combines the providers and processes we know with new forms of currency, may act as a transitional tool.

Microsoft AirSim: open-source simulator for autonomous vehicles

  • AirSim is a simulator for drones, cars and more, built on Unreal Engine (we now also have an experimental Unity release).
  • Our goal is to develop AirSim as a platform for AI research to experiment with deep learning, computer vision and reinforcement learning algorithms for autonomous vehicles.
  • For this purpose, AirSim also exposes APIs to retrieve data and control vehicles in a platform independent way.
  • AirSim exposes APIs so you can interact with the vehicle in the simulation programmatically.
  • You can use these APIs to retrieve images, get state, control the vehicle and so on.
  • Note that you can use SimMode setting to specify the default vehicle or the new ComputerVision mode so you don't get prompted each time you start AirSim. There are two ways you can generate training data from AirSim for deep learning.

What is GraphQL and why I should use it?

  • Clients need to be authenticated, authorised and then request data for those transactions to happen.
  • GraphQL queries help you to fetch only the records and attributes you need - we have seen examples earlier.
  • Use GraphQL to fetch records with specified relationships, rather than making separate requests for distinct entities.
  • Server receives GraphQL requests from clients, establishes connection to database, converts graph queries to a language understood by database, fetches results and sends the responses back to clients.
  • The schema definition helps a client-side developer to see and understand the relationships b/w data entities, and thereon construct a GraphQL query.
  • Use GraphQL when you need to fetch a lot of data having varying shapes / many relationships.
  • Use GraphQL to simplify the data passed between client and server.

12 AI startups that will boom in 2019, according to VCs

  • Venture capitalists are the startup experts, the ones who have their finger on the pulse of which fledgling companies will boom and which will bust.
  • They told us about companies they currently have in their portfolios, as well as ones they haven't put any money into yet but are at the center of positive news.
  • And from those discussions, one particular group of startups came up repeatedly: those that specialize in artificial intelligence tech.
  • From AI robots to software that uses machine learning to automate tasks, Silicon Valley is chock full of AI-focused startups.
  • Take, for example, Transfix, a freight marketplace that companies use to hire trucks from carriers.
  • The startup is trying to transform the $800 billion trucking industry by using AI to match loads with carriers.
