RefineNet Model

The go-to method for Semantic Segmentation has been deep CNN but this method has a limitation where the segmentation process is performed on down-sampled versions of input data, hence they perform poorly when it comes to high-resolution segmentation. This can be improved by other methods in a trade-off between, model implementation requirements like time and space for better resolution. An effective alternative solution is RefineNet Model.

EEG Signal Analysis With Python

Introduction

In this article, we will learn how to process EEG signals with Python using the MNE-Python library.

Table of ContentsIntroduction to EEGInstallation/SetupLoading dataPlotting EEG SignalsPreprocessingEpochingConclusionIntroduction to EEG

Electroencephalography (EEG) is a technique for continuously recording brain activity in the form of brainwaves. EEG is commonly used because it provides a noninvasive, easy, and inexpensive method to measure neural activity at a high resol...

Hibernate Annotations

Hibernate is an open-source Java ORM tool that is used between the Java application and the JDBC that connects to the database. To put the hibernate into work we need to provide three things:

Hibernate Configuration - to configure caching strategies, SQL statement logging in the console, etc.Database connection details - database credentials like driver class, username, password, and connection URL, to connect to the databaseMapping details - to map the entity classes to database tables

Hibernate Inheritance Mapping

Hibernate is an implementation of JPA specification. Hibernate effectively takes care of the fundamental difference between how OOPs and RDBMS deal with data and provides ease of programming. Implementing various strategies for mapping hibernate deals with various Object-Relational Impedance mismatches.

In this article, we are going to learn various strategies of inheritance mapping that hibernate implements to deal with Inheritance Object-Relational Impedance Mismatch.
