Face Recognition in Unconstrained Conditions: a Systematic Review
Face Recognition in Unconstrained Conditions: A Systematic Review ANDREW JASON SHEPLEY, Charles Darwin University, Australia ABSTRACT Face recognition is a biometric which is attracting significant research, commercial and government interest, as it provides a discreet, non-intrusive way of detecting, and recognizing individuals, without need for the subject’s knowledge or consent. This is due to reduced cost, and evolution in hardware and algorithms which have improved their ability to handle unconstrained conditions. Evidently affordable and efficient applications are required. However, there is much debate over which methods are most appropriate, particularly in the context of the growing importance of deep neural network-based face recognition systems. This systematic review attempts to provide clarity on both issues by organizing the plethora of research and data in this field to clarify current research trends, state-of-the-art methods, and provides an outline of their benefits and shortcomings. Overall, this research covered 1,330 relevant studies, showing an increase of over 200% in research interest in the field of face recognition over the past 6 years. Our results also demonstrated that deep learning methods are the prime focus of modern research due to improvements in hardware databases and increasing understanding of neural networks. In contrast, traditional methods have lost favor amongst researchers due to their inherent limitations in accuracy, and lack of efficiency when handling large amounts of data. Keywords: unconstrained face recognition, deep neural networks, feature extraction, face databases, traditional handcrafted features 1 INTRODUCTION The development of accurate and efficient face recognition systems for use in unconstrained conditions is an area of high research interest. -

As researchers and engineers develop and apply these technologies to make consequential decisions in everyone’s lives, it is crucial that the public under- stands the AI-powered world, can discuss AI policies, and become empowered to engage in shaping these technologies’ futures. Historically, ML application devel- opment has been accessible only to those with strong computational backgrounds working or conducting research in highly technical fields. As ML models become more powerful and computing hardware becomes faster and cheaper, it is now tech- nologically possible for anyone with a laptop to learn about and tinker with ML. -

Notes on Andrew Ng's CS 229 Machine Learning Course
Notes on Andrew Ng’s CS 229 Machine Learning Course Tyler Neylon 331.2016 These are notes I’m taking as I review material from Andrew Ng’s CS 229 course on machine learning. Specifically, I’m watching these videos and looking at the written notes and assignments posted here. These notes are available in two formats: html and pdf. I’ll organize these notes to correspond with the written notes from the class. As I write these notes, I’m also putting together some homework solutions. 1 On lecture notes 1 The notes in this section are based on lecture notes 1. 1.1 Gradient descent in general Given a cost function J(θ), the general form of an update is ∂J θj := θj − α . ∂θj It bothers me that α is an arbitrary parameter. What is the best way to choose this parameter? Intuitively, it could be chosen based on some estimate or actual value of the second derivative of J. What can be theoretically guaranteed about the rate of convergence under appropriate conditions? Why not use Newton’s method? A general guess: the second derivative of J becomes cumbersome to work with. It seems worthwhile to keep my eye open for opportunities to apply improved optimization algorithms in specific cases. 1 1.2 Gradient descent on linear regression I realize this is a toy problem because linear regression in practice is not solve iteratively, but it seems worth understanding well. The general update equation is, for a single example i, (i) (i) (i) θj := θj + α(y − hθ(x ))xj . -

We’ll take a deep dive into the past, present, and future of AI, machine learning, neural networks, and other cutting-edge technologies. Here is your host, Beena. Beena Ammanath (Beena): Hello, my name is Beena Ammanath, and I am the executive director for Deloitte AI Institute. And today on AI Ignition, we have Dr. Andrew Ng. Andrew is a world-renowned leader in the space of AI. He is the founder and CEO of Landing AI, he is the founder of Deeplearning.AI, and he is the general partner for AI fund. Welcome, Andrew. Andrew Ng (Andrew): Thank you, Beena. Good to see you here. I think despite the circumstances in society and the global tragedy of the pandemic, I think many of us are privileged to have work of a nature that we could do it from home. Beena: Yes, absolutely, totally agree with you. Now, I am curious to hear, because you do so much, you do a lot, you lead a number of companies. Can you share a day in the life of Dr. Andrew Ng? Andrew: I spend a lot of time working. I am privileged to genuinely love my work. The other day I woke up at 5 a.m. on a Monday morning just excited to start work. I’m probably not setting a good example, probably other people shouldn’t do that. -

The main advantage of using neural network methods in this project is its adeptness at fitting nonlinear data and its ability to work as an unsupervised algorithm. The algorithms will be run on common, publically available datasets, namely the MNIST and CIFAR10, so that our results will be easily reproducible. -
