Introduction

In recent times, Artificial Intelligence and Machine Learning significantly impacted different sectors. The deep learning domain stands out in solving various complex problems among other branches. However, traditional deep learning models are optimized for regular grid-like data, such as images and sequences, etc., leaving out an essential aspect of many real-world datasets like geometric relationships where Geometric Deep Learning (GDL) plays a crucial role.

Introduction To Geometric Deep Learning

This article will see an overview and introduction to Geometric Deep Learning application of geometric deep learning.

What is Deep Learning? 

Deep learning is a domain of machine learning where it trains an artificial neural network to mimic the human brain's structure and functionality. This neural network consists of multiple layers. Each layer is responsible for learning specific features from the input data. With the help of backpropagation and gradient descent, deep learning models adjust their parameters to minimize error and improve performance in image recognition, natural language processing, and more.

What is Geometric Deep Learning?

Geometric deep learning is a field of machine learning in which the machine learns from complex data represented through graphs or multi-dimensional points. Graphs are a way of describing systems of affiliated objects. Thus, graph data processing has operations in numerous fields, like biology, transportation, natural language processing, and social networks. Computing and learning on graphs is an arising exploration content also in computer vision. Point shadows, for illustration of a  mortal body, are implicitly big graphs where vertices are the scrutinized points and edges are the( semantic) relations that link similar points to form the face.

What is Geometric Deep Learning?

A decreasingly active field of exploration regards the family of machine literacy ways called Graph Neural Networks( GNN). It can also be used to interpret point shadows. Among them, motor armature, a particular case of GNNs, is now competitive with Convolutional Neural Network models. Geometric machine literacy is explosively related to graph machine and representation literacy. Developing models for geometric deep literacy is an exploration area of interest.

The Intersection of Geometry and Deep Learning

At the core of Geometric Deep Learning lies the fusion of deep learning and graph theory. Traditional deep learning techniques are limited when applied to graph data. Since they fail to capture the inherent geometric relationships in graphs. GDL aims to remedy this by developing specialized neural network architectures that can operate on charts effectively. These architectures include graph convolutional networks, graph attention mechanisms, and graph pooling operations. This enables GDL models to learn from graph-structured data and generalize to new, unseen examples. In short, the field of Geometric Deep Learning has three main contributions.:

  • We can make use of non-euclidean data.
     
  • We can maximize the information from the data we collect.
     
  • We can use this data to teach machine-learning algorithms.

Application of Geometric Deep Learning 

Following are the application of geometric deep learning:
 

  • Landmarks are learning for topological navigation.
     
  • Simulation of detecting object process of human vision behavior.
     
  • Learning self-generated action.
     
  • Vehicle tracking.

Future Directions

Geometric deep learning was an emerging field that aimed to extend deep learning techniques to structured data. This included graphs and manifolds. Geometric Deep Learning can now be used in the front lines of companies like Pinterest, Twitter, Uber, and Accenture. This list goes on to cover just about every company with a finger in the field of ML. In academia, Graph Representation Learning.
