A First Glimpse of Rigetti’s Quantum Computing Cloud

Quantum computing has been picking up the momentum, and there are many startups and scholars discussing quantum machine learning. A basic knowledge of quantum two-level computation ought to be acquired. Recently, Rigetti, a startup for quantum computing service in Bay Area, published that they opened to public their cloud server for users to simulate the … More A First Glimpse of Rigetti’s Quantum Computing Cloud

Short Text Categorization using Deep Neural Networks and Word-Embedding Models

There are situations that we deal with short text, probably messy, without a lot of training data. In that case, we need external semantic information. Instead of using the conventional bag-of-words (BOW) model, we should employ word-embedding models, such as Word2Vec, GloVe etc. Suppose we want to perform supervised learning, with three subjects, described by … More Short Text Categorization using Deep Neural Networks and Word-Embedding Models

Linking Fundamental Physics to Deep Learning

Ever since Mehta and Schwab laid out the relationship between restricted Boltzmann machines (RBM) and deep learning mathematically (see my previous entry), scientists have been discussing why deep learning works so well. Recently, Henry Lin and Max Tegmark put a preprint on arXiv (arXiv:1609.09225), arguing that deep learning works because it captures a few essential … More Linking Fundamental Physics to Deep Learning

On Quantum Computing…

Justin Trudeau, the Canadian Prime Minister, rocked the world recently by talking about quantum computers in front of reporters at Perimeter Institute… No fault can be found in his answer, although his answer cannot be more layman. A few physicists were challenged to give a layman introduction about quantum computers, and they are equally well. … More On Quantum Computing…

Topology in Physics and Computing

Topology has been shown to reveal important information about geometry and shape from data, [Carlsson 2015][Carlsson 2009]¬†as I have talked about in various TDA blog entries. I have also demonstrated how to describe the topology if discrete data points by constructing simplicial complexes, and then calculated the homology and Betti numbers. (I will talk about … More Topology in Physics and Computing
