Echart polar coordinates, azimuth and distance diagram, icon symbol rotation and size, color gradient

Background: Participating in an interactive chart project, the customer had a need for polar coordinate comparison to display different types of indicator data in different directions and distances. Specifically, the attribute fields are: Source, distance, orientation, ID, rotation angle, size Let’s look at the renderings first: Technical points: Legend description: The distance is the radial […]

TrOCR model fine-tuning [Transformer-based optical character recognition]

The TrOCR (Transformer-based Optical Character Recognition) model is one of the best performing OCR models. In our previous article we analyzed their performance on single lines of printed and handwritten text. However, like any other deep learning model, they have their limitations. TrOCR doesn’t perform well with curved text out of the box. This article […]

Deep Neural Network (DNN) is an artificial neural network characterized by having multiple layers of neurons

Deep Neural Network (DNN) is an artificial neural network, which is characterized by having multiple layers of neurons, which can better handle complex nonlinear problems. In Java, we can use open source libraries such as Deeplearning4j (DL4J) to implement deep neural networks. In DL4J, a basic deep neural network consists of multiple layers, each containing […]
