Crowd-Acting™: How to Grow Large-Scale Video Datasets for Deep Learning
In this post, we discuss the limitations to the traditional data collection approach and illustrate how to use crowd-acting, an innovative approach, to grow large-scale video datasets for deep learning. Our crowd-acted datasets Jester and Something-Something are publicly released and free for academic purposes.

Hello, World: Building an AI that understands the world through video
Machines today can identify objects in images, but they are unable to fully decipher the most important aspect: what’s actually happening in front of the camera. At TwentyBN, we have created the world’s first AI technology that shows an awareness of its environment and of the actions occurring within it. Our system observes the world through live video and automatically interprets the unfolding visual scene. Check it out yourself:

Our mission

When humans perform tasks and solve problems, they rely heavily on their common sense knowledge about the world. A detailed understanding of the physical world is however still largely missing from current applications in artificial intelligence and robotics. Our mission is to change that. We are developing new, ground-breaking technology that allows machines to perceive the world like humans.

How it works

Our technology can analyze human actions and extract real-time information from video streams. We build deep learning systems using our large video datasets about common world situations and then fine-tune them to specific use cases with minimal effort.

A novel database

One of the limiting factors for advancing video understanding is the lack of large and diverse real-world video datasets. To circumvent this bottleneck, we have built a scalable crowd-acting™ platform and have created some of the largest industry video datasets for training deep neural networks.

A unique approach

Our deep neural networks are pre-trained on our datasets of crowd-acted videos. The datasets contain short video clips that show a wide range of physical and human actions. We then transfer the capabilities of our trained network to contribute to specific video applications.

Use Cases

Our machine learning systems excel at deciphering complex human behavior in video

Gesture Recognition
Automatic detection of dynamic hand gestures for human-computer interaction
Personal Home Robots
Visual scene understanding for domestic robots interacting with humans
Elderly Fall Detection
Automatic detection of accidental falls among elderly people at home
In-car monitoring
Automatic detection of driver and passenger behaviors
Our Data Factory

Our Data Factory

Through crowd-acting™, we are constantly growing our large-scale datasets that help machines to see and understand the world.
