Pose-Aware Face Recognition in the Wild

Pose-Aware Face Recognition in the Wild

We propose a method to push the frontiers of unconstrained face recognition in the wild, focusing on the problem of extreme pose variations.

We leverage deep Convolutional Neural Networks (CNNs) to learn discrimi-native representations we call Pose-Aware Models (PAMs)using 500K images from the CASIA WebFace dataset.

DSD: Regularizing Deep Neural Networks with Dense-Sparse-Dense Training Flow

DSD: Regularizing Deep Neural Networks with Dense-Sparse-Dense Training Flow

Experiments show that DSD training can improve the performance of a wide range of CNN, RNN and LSTMs on the tasks of image classification, caption generation and speech recognition.

Funnel-Structured Cascade for Multi-View Face Detection with Alignment-Awareness

Funnel-Structured Cascade for Multi-View Face Detection with Alignment-Awareness

we propose a novel funnel-structured cascade (FuSt) detection framework. In a coarse-to-fine flavor, our FuSt consists of, from top to bottom, 1) multiple view-specific fast LAB cascade for extremely quick face proposal, 2) multiple coarse MLP cascade for further candidate window verification, and 3) a unified fine MLP cascade with shape-indexed features for accurate face detection.

Paying More Attention to Attention: Improving the Performance of Convolutional Neural Networks via Attention Transfer

We show that activation-based attention transfer gives better improvements than full activation transfer, and can be combined with knowledge distillation

Ordinal Regression with Multiple Output CNN for Age Estimation

Ordinal Regression with Multiple Output CNN for Age Estimation

we propose an End-to-End learning approach to address ordinal regression problems using deep Convolutional Neural Network, which could simultaneously conduct feature learning and regression modeling

we publish an Asian Face Age Dataset (AFAD) containing more than 160K facial images with precise age ground-truths, which is the largest public age dataset to date.

this is the first work to address ordinal regression problems by using CNN, and achieves the state-of-the-art performance on both the MORPH and AFAD datasets

dataset

training, testing set

Following the experimental setting in [6][7][31], for both MORPH II and AFAD datasets, we randomly divide the whole dataset into two parts: one part (i.e., 80% of the whole data) is used for training, and the other one (i.e., 20% of the whole data) is used for testing.

performance

The performance is measured by the Mean Absolute Error (MAE) metric and the Cumulative Score (CS).

Age and Gender Classification using Convolutional Neural Networks

Age and Gender Classification using Convolutional Neural Networks

we propose a simple convolutional net architecture that can be used even when the amount of learning data is limited.

We evaluate our method on the recent Adience benchmark for age and gender estimation and show it to dramatically outperform current state-of-the-art methods.

Motion-based countermeasures to photo attacks in face recognition

Motion-based countermeasures to photo attacks in face recognition

The Replay-Attack Database for face spoofing consists of 1300 video clips of photo and video attack attempts to 50 clients, under different lighting conditions. This Database was produced at the Idiap Research Institute, in Switzerland.

Unsupervised Representation Learning with Deep Convolutional Generative Adversarial Networks

Why does deep and cheap learning work so well?

Why does deep and cheap learning work so well?

we explore how these properties translate into exceptionally simple neural networks approximat-
ing both natural phenomena such as images and abstract representations thereof such as drawings.

We further argue that when the statistical process generating the data is of a certain hierarchical form prevalent in physics and machine-learning, a deep neural network can be more efficient than a shallow one.
