Word2vec is a powerful machine learning tool that emerged from Natural Language Processing (NLP) and is now applied in multiple domains including recommender systems, forecasting, and machine learning on graphs. It is often used off the shelf and we address the question of whether the default hyperparameters, which were originally tuned on NLP tasks are suitable for recommender systems. The answer is emphatically no. For an unconstrained hyperparameter search running to convergence, we measure… Show more

Word2vec is a powerful machine learning tool that emerged from Natural Language Processing (NLP) and is now applied in multiple domains including recommender systems, forecasting, and machine learning on graphs. It is often used off the shelf and we address the question of whether the default hyperparameters, which were originally tuned on NLP tasks are suitable for recommender systems. The answer is emphatically no. For an unconstrained hyperparameter search running to convergence, we measure an average increase in hit rate of 221%. However, this is achieved by using orders of magnitude more computational resources. Surprisingly, even when the runtime is fixed to the out of the box runtime, constrained optimization leads to an average 138% improvement in hit rate. For large scale systems, full hyperparameter optimization on production datasets is not possible and we tackle the question of estimating the optimal hyperparameters from a sample. We find that by applying constrained optimization to a 10% sample of the data and applying the hyperparameters found from the sample to the full datasets an average hit rate improvement of 91% above the default parameters is achieved.

Compositionality May 2020

In this work we take a Category Theoretic perspective on the relationship between probabilistic modeling and function approximation. We begin by defining two extensions of function composition to stochastic process subordination: one based on the co-Kleisli category under the comonad (Omega x -) and one based on the parameterization of a category with a Lawvere theory. We show how these extensions relate to the category Stoch and other Markov Categories. Next, we apply the Para construction to… Show more

In this work we take a Category Theoretic perspective on the relationship between probabilistic modeling and function approximation. We begin by defining two extensions of function composition to stochastic process subordination: one based on the co-Kleisli category under the comonad (Omega x -) and one based on the parameterization of a category with a Lawvere theory. We show how these extensions relate to the category Stoch and other Markov Categories. Next, we apply the Para construction to extend stochastic processes to parameterized statistical models and we define a way to compose the likelihood functions of these models. We conclude with a demonstration of how the Maximum Likelihood Estimation procedure defines an identity-on-objects functor from the category of statistical models to the category of Learners.

Artificial Intelligence and Machine Learning for Digital Pathology - LNCS 12090 2020

This paper reviews guidelines on how medical imaging analysis can be enhanced by Artificial Intelligence (AI) and Machine Learning (ML). In addition to outlining current and potential future developments, we also provide background information on chemical imaging and discuss the advantages of Explainable AI. We hypothesize that it is a matter of AI to find an invariably recurring parameter that has escaped human attention (e.g. due to noisy data). There is great potential in AI to illuminate… Show more

ICLR 2019 (International Conference on Learning Representations) Dec 2018

Most recent gains in visual recognition have originated from the inclusion of attention mechanisms in deep convolutional networks (DCNs). Because these networks are optimized for object recognition, they learn where to attend using only a weak form of supervision derived from image class labels. Here, we demonstrate the benefit of using stronger supervisory signals by teaching DCNs to attend to image regions that humans deem important for object recognition. We first describe a large-scale… Show more

Most recent gains in visual recognition have originated from the inclusion of attention mechanisms in deep convolutional networks (DCNs). Because these networks are optimized for object recognition, they learn where to attend using only a weak form of supervision derived from image class labels. Here, we demonstrate the benefit of using stronger supervisory signals by teaching DCNs to attend to image regions that humans deem important for object recognition. We first describe a large-scale online experiment (ClickMe) used to supplement ImageNet with nearly half a million human-derived "top-down" attention maps. Using human psychophysics, we confirm that the identified top-down features from ClickMe are more diagnostic than "bottom-up" saliency features for rapid image categorization. As a proof of concept, we extend a state-of-the-art attention network and demonstrate that adding ClickMe supervision significantly improves its accuracy and yields visual features that are more interpretable and more similar to those used by human observers.

The PopGen Simulator is a GUI­based interactive tool for teaching students about population genetics and computer simulation. Students use the program to simulate the growth and evolution of a population at the genomic level. Users select between a variety of different models, specify the parameters of the model, and visualize the results. Students in the Brown University Course “Computational Theory of Molecular Evolution and Population Genetics,” used the simulator to reinforce concepts and validate mathematical reasoning. For example, in one laboratory exercise students ran multi-locus simulations with a variety of mutation rates and number of loci, and reasoned about the resulting population evolution.

In addition to its teaching applications, the PopGen Simulator can also be used to generate synthetic data and includes an API that researchers can use to quickly prototype and visualize their models. The simulator is written in MATLAB, and also includes a command line component. Show less
