AI Funds Decline--Then Recover--During Market Turmoil

#artificialintelligence

Traders that use machine learning have had to adjust strategies and rely less on historical data to train models.


r/MachineLearning - [P] I wrote an API to build neural networks in Minecraft

#artificialintelligence

You could design CPU for running binarized neural networks pretty easily. Basically, the multiplication operation is XNOR and the reduction operation can be designed in redstone. The most complicated part would be to design memory and bus interface to this CPU. Plus I think, pure redstone neural network would be very laggy because of waaay to many block and lighting updates. People have implemented neural networks using command block before.


r/MachineLearning - [R] OpenAI opensources Jukebox, a neural net that generates music

#artificialintelligence

I'm very glad that the article includes a "Limitations" section, because while to most untrained listeners (and even trained listeners), these samples seem miraculous, in reality what is happening is that this is simply a more-impressive version of what has already been available. Specifically, Jukebox is able to provide locally-coherent sounds, which are recognizable as "music", but over long-term horizons it loses large-scale structure. They mention this themselves, and rightly so. While this is very impressive, it is primarily just an exercise in how nice they are able to make their short-term "sentences" sound (to borrow an analogy from speech synthesis). However, the broader challenge of long-term structure and musical form (here an analogy might be novel-length narrative structure) remains an open problem.


r/MachineLearning - [R] Consistent Video Depth Estimation

#artificialintelligence

Abstract: We present an algorithm for reconstructing dense, geometrically consistent depth for all pixels in a monocular video. We leverage a conventional structure-from-motion reconstruction to establish geometric constraints on pixels in the video. Unlike the ad-hoc priors in classical reconstruction, we use a learning-based prior, i.e., a convolutional neural network trained for single-image depth estimation. At test time, we fine-tune this network to satisfy the geometric constraints of a particular input video, while retaining its ability to synthesize plausible depth details in parts of the video that are less constrained. We show through quantitative validation that our method achieves higher accuracy and a higher degree of geometric consistency than previous monocular reconstruction methods.


r/MachineLearning - [D] AI21 Labs Asks: How Much Does It Cost to Train NLP Models?

#artificialintelligence

AI21 Labs Co-CEO, Stanford University Professor of Computer Science (emeritus), and AI Index initiator Yoav Shoham describes the motivation for the project. "It started with an inquiry we got at the AI Index. I started jotting down a quick answer and realized it deserved a longer one. I also realized we had a lot of the expertise at AI21 Labs. So we spun up a small effort to put this report together, to benefit the community."


r/deeplearning - What to expect from Deep Learning Book

#artificialintelligence

Hi, new to deep learning and know almost all the high-level concepts and implemented some with the help of tutorials. I am looking to advance my career and thinking to buy Deep Learning Book by Goodfellow. What should I expect from this book? Also, do you have any better recommendations?


r/deeplearning - Can someone briefly explain the latent loss part of Variational autoencoder?

#artificialintelligence

They consist of a probabilistic decoder and a probabilistic encoder. Probabilistic encoder encodes the input data into a Gaussian multivariate distribution, such that it produces a mean vector and a diagonal covariance matrix. The dimension of this distribution is determined by how many nodes you have in the latent layer. Then, probabilistic decoder samples the encoded distribution and creates the reconstructed data after forward propagating the sample. The loss function (to be minimized) consists of two parts: negative reconstruction likelihood ensuring that it will be likely to produce data similar to those in training dataset, and KL divergence from a prior Gaussian (usually N(0,I)) which acts as a regularizer.


r/deeplearning - Open-Source Repository of Forecasting Best Practices

#artificialintelligence

The repository also comes with Azure Machine Learning (Azure ML) themed notebooks and best practices recipes to accelerate the development of scalable, production-grade forecasting solutions on Azure. You will find the following examples for forecasting with Azure AutoML as well as tuning and deploying a forecasting model on Azure. Developing an accurate forecasting solution can be a complex and time-consuming process. We hope the forecasting repo will help shorten your development cycle on Azure.


Can Artificial Intelligence Reprogram the Newsroom?

#artificialintelligence

Could a computer program write engaging news stories? In a recent Technology Trends and Predictions report from Reuters, 78% of the 200 digital leaders, editors, and CEOs surveyed said investing in artificial intelligence (AI) technologies would help secure the future of journalism (Newman, 2018). Exploring these new methods of reporting, however, has introduced a wide array of unforeseen ethical concerns for those already struggling to understand the complex dynamics between human journalists and computational work. Implementing automated storytelling into the newsrooms presents journalists with questions of how to preserve and encourage accuracy and fairness in their reporting and transparency with the audiences they serve. Artificial intelligence in the newsroom has progressed from an idea to a reality.
