Computer vision
NeuralMVS: Bridging Multi-View Stereo and Novel View Synthesis (arXiv:2108.03880)
tl;dr Multi-view stereo is a core task in 3D computer vision. NeRF methods do not generalize to novel scenes and are slow to train and test. We propose to bridge the gap between these two methodologies with a novel network that can recover 3D scene geometry as a distance function.[1]
Simulation
iGibson 2.0: Object-Centric Simulation for Robot Learning of Everyday Household Tasks (arXiv:2108.03272)
tl;dr iGibson 2.0 is a novel simulation environment using Bullet that supports the simulation of a more diverse set of household tasks through three key innovations. Firstly, it supports object states, including temperature, wetness level, cleanliness level, and toggled and sliced states, necessary to cover a wider range of tasks. Second, it implements a set of predicate logic functions that map the simulator states to logic states like Cooked or Soaked. Third, the simulator can sample valid physical states that satisfy a logic state. This functionality can generate potentially infinite instances of tasks with minimal effort from the users.[2]

Audio processing
SoundStream: An End-to-End Neural Audio Codec (arXiv:2107.03312)
tl;dr A novel neural audio codec that can efficiently compress speech, music and general audio at bitrates normally targeted by speech-tailored codecs. SoundStream at 3kbps outperforms Opus at 12kbps and approaches EVS at 9.6kbps.[3]

Multimodal learning
Multimodal Few-Shot Learning with Frozen Language Models (arXiv:2106.13884)
tl;dr When trained at sufficient scale, auto-regressive language models exhibit the notable ability to learn a new language task after being prompted with just a few examples. Here, the authors present a simple, yet effective, approach for transferring this few-shot learning ability to a multimodal setting (vision and language).[4]
Optimizers
A Generalizable Approach to Learning Optimizers (arXiv:2106.00958)
tl;dr Learning to update optimizer hyperparameters instead of model parameters directly using novel features, actions, and a reward function.[5]
May 2021
Memory
Not All Memories are Created Equal: Learning to Forget by Expiring (arXiv:2105.06548)
tl;dr The authors propose Expire-Span, a method that learns to retain the most important information and expire the irrelevant information, which enables Transformers to scale to attend over tens of thousands of previous timesteps efficiently.[6]
April 2021
Fine-tuning
The Power of Scale for Parameter-Efficient Prompt Tuning (arXiv:2104.08691)
tl;dr In this work, the author's explore "prompt tuning" a simple but effective mechanism for learning "soft prompts" to condition frozen language models to perform specific downstream tasks.[7]
October 2020
Computer vision
GRF: Learning a General Radiance Field for 3D Scene Representation and Rendering (arXiv:2010.04595)
tl;dr General Radiance Fields construct an internal representation for each 3D point of a scene from 2D inputs and renders the corresponding appearance and geometry of any 3D scene viewing from an arbitrary angle.[8]

Summarization
Learning to Summarize with Human Feedback (arXiv:2009.01325)
tl;dr Human feedback models outperform much larger supervised models and reference summaries on TL;DR.[9]
