Deep Learning - Object Detection

In the last article series written by my colleague, we learned image classification and its implementation. Now we are going to take a glance at the science of object detection. Whereas image classification returns a class and probability for the whole image, object detection finds a list of objects on the image and returns it for […]

Spatial Data in .NET

Spatial data contains information about geometrical properties of a certain entity, such as the position, length and surface area. This kind of data could theoretically also be stored using conventional data types, but it would be quite inconvenient for processing. Therefore, many database systems and software frameworks support using special datatypes for spatial data. In this post handling spatial data in the .NET Framework will be covered.

Deep Learning Neural Networks – PART ONE

The most well-known deep learning architectures are certainly deep neural networks, DBF (deep belief network), and recurrent neural networks. Some of the fields where deep learning can be applied are computer vision, speech recognition, sound recognition, social filtering network, bioinformatics, drug design, advanced image processing, segmentation, whatever data has a time component, etc. In many scenarios, deep learning has shown equal and even superior results in relation to human expertise.

What to Consider Before Using JWT

We know that JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed.

Introduction to JWT

For a long time, user authentication on the web consisted of storing pieces of very simple data (like a user ID) in the user's browser as a cookie. This worked pretty well – and still does for many applications – but sometimes you require more flexibility.

Using Futures in Flutter

Long-running tasks or asynchronous operations are common in mobile apps. For example, these operations can be fetching data over network, writing to database, reading data from a file, etc. To perform such operations in Flutter/Dart, we usually use a Future class and the keywords async and await. A Future class allows you to run work asynchronously to free up any other threads that should not be blocked. Like the UI thread.

Metrics, Logging and Tracing Are Just Data

Usually we think of logging and tracing data as continuously updated long chronologically ordered lines or records organized in plain text files with a relatively simple purpose – to keep record of the operating system, network, application or of service events and activities.
