Het-node2vec: second order random walk sampling for heterogeneous multigraphs embedding
We introduce a set of algorithms (Het-node2vec) that extend the original node2vec node-neighborhood sampling method to heterogeneous multigraphs, i. e. networks characterized by multiple types of nodes and edges.

Enabling Machine Learning-Ready HPC Ensembles with Merlin
With the growing complexity of computational and experimental facilities, many scientific researchers are turning to machine learning (ML) techniques to analyze large scale ensemble data.
Parallelizing Training of Deep Generative Models on Massive Scientific Datasets
Training deep neural networks on large scientific data is a challenging task that requires enormous compute power, especially if no pre-trained models exist to initialize the process.
Atomic Crosschain Transactions for Ethereum Private Sidechains
Ethereum Private Sidechains is a private blockchain technology which allows many blockchains to be operated in parallel.

Anonymous State Pinning for Private Blockchains
Existing solutions offering pinning to the public blockchain would reveal the transaction rate of the private blockchain, and do not provide a mechanism to contest the validity of a pin.

GazeDirector: Fully Articulated Eye Gaze Redirection in Video
We present GazeDirector, a new approach for eye gaze redirection that uses model-fitting.
An Empirical Study of Recent Face Alignment Methods
In this paper, we carry out a rigorous evaluation of these methods by making the following contributions: 1) we proposes a new evaluation metric for face alignment on a set of images, i. e., area under error distribution curve within a threshold, AUC$_\alpha$, given the fact that the traditional evaluation measure (mean error) is very sensitive to big alignment error.
Human and Sheep Facial Landmarks Localisation by Triplet Interpolated Features
Furthermore, we study the impact of training data imbalance on model performance and propose a training sample augmentation scheme that produces more initialisations for training samples from the minority.
Face Alignment Assisted by Head Pose Estimation
In this paper we propose a supervised initialization scheme for cascaded face alignment based on explicit head pose estimation.
Rendering of Eyes for Eye-Shape Registration and Gaze Estimation
Images of the eye are key in several computer vision problems, such as shape registration and gaze estimation.
