- Reinforcement Learning with Prediction-Based Rewards
Impressive results from OpenAI: “We’ve developed Random Network Distillation (RND), a prediction-based method for encouraging reinforcement learning agents to explore their environments through curiosity, which for the first time1 exceeds average human performance on Montezuma’s Revenge.”
- Spinning Up in Deep RL
More from OpenAI: “We’re releasing Spinning Up in Deep RL, an educational resource designed to let anyone learn to become a skilled practitioner in deep reinforcement learning. Spinning Up consists of crystal-clear examples of RL code, educational exercises, documentation, and tutorials.”
- My secret sauce to be in top 2% of a kaggle competition
“I developed some standard ways to explore features and build better machine learning models. These simple, but powerful techniques helped me get a top 2% rank in Instacart Market Basket Analysis competition.”
- Horizon: Facebook’s Open Source Applied Reinforcement Learning Platform
“Horizon is an end-to-end platform designed to solve industry applied RL problems where datasets are large (millions to billions of observations), the feedback loop is slow (vs. a simulator), and experiments must be done with care because they don’t run in a simulator.” An interesting take on the normal RL environments!
- Generating custom photo-realistic faces using AI
Controlled image synthesis and editing using a novel TL-GAN model.
- Zero-shot learning: Using text to more accurately identify images
Researchers at Facebook have developed a new, more accurate ZSL model that uses neural net architectures called generative adversarial networks (GANs) to read and analyze text articles, and then visually identify the objects they describe. This novel approach to ZSL allows machines to classify objects based on category, and then use that information to identify other similar objects, as opposed to learning each object individually, as other models do.
- Extended Isolation Forest for Anomaly Detection
“This is a simple package implementation for the Extended Isolation Forest method. It is an improvement on the original algorithm Isolation Forest. The original algorithm suffers from an inconsistency in producing anomaly scores due to slicing operations. Even though the slicing hyperplanes are selected at random, they are always parallel to the coordinate reference frame. The shortcoming can be seen in score maps as presented in the example notebooks in this repository. In order to improve the situation, we propose an extension which allows the hyperplanes to be taken at random angles. The way in which this is done gives rise to multiple levels of extension depending on the dimensionality of the problem. For an N dimensional dataset, Extended Isolation Forest has N levels of extension, with 0 being identical to the case of standard Isolation Forest, and N-1 being the fully extended version.”
- A (Long) Peek into Reinforcement Learning

- Raster Vision: A New Open Source Framework for Deep Learning on Satellite and Aerial Imagery
Azavea announces the release of Raster Vision, a new open source framework for deep learning on satellite and aerial imagery.
- Improving AI language understanding by combining multiple word representations
“A novel approach to using word embeddings (where words or phrases are mapped to sequences of numbers that represent their meaning) for natural language processing (NLP) that dynamically selects the right types of embeddings for the task at hand. These dynamic meta-embeddings outperform similar models that use a single type of word embedding. Facebook’s AI researchers have open-sourced this code.”
- Drilling Down on Depth Sensing and Deep Learning
“This post explores two independent innovations and the potential for combining them in robotics. Two years before the AlexNet results on ImageNet were released in 2012, Microsoft rolled out the Kinect for the X-Box. This class of low-cost depth sensors emerged just as Deep Learning boosted Artificial Intelligence by accelerating performance of hyper-parametric function approximators leading to surprising advances in image classification, speech recognition, and language translation. Today, Deep Learning is also showing promise for end-to-end learning of playing video games and performing robotic manipulation tasks.”
