BrainCog is an open source spiking neural network based brain-inspired cognitive intelligence engine for Brain-inspired Artificial Intelligence and brain simulation. More information on BrainCog can be found on its homepage http://www.brain-cog.network/
The current version of BrainCog contains at least 18 functional spiking neural network algorithms (including but not limited to perception and learning, decision making, knowledge representation and reasoning, motor control, social cognition, etc.) built based on BrainCog infrastructures, and BrainCog also provide brain simulations to drosophila, rodent, monkey, and human brains at multiple scales based on spiking neural networks at multiple scales. More detail in http://www.brain-cog.network/docs/
BrainCog is a community based effort for spiking neural network based artificial intelligence, and we welcome any forms of contributions, from contributing to the development of core components, to contributing for applications.
BrainCog provides essential and fundamental components to model biological and artificial intelligence.

}BrainCog currently provides cognitive functions components that can be classified into five categories:
- Perception and Learning
- Decision Making
- Motor Control
- Knowledge Representation and Reasoning
- Social Cognition
BrainCog currently include two parts for brain simulation:
- Brain Cognitive Function Simulation
- Multi-scale Brain Structure Simulation
The anatomical and imaging data is used to support our simulation from various aspects.

In addition to the static datasets, BrainCog supports the commonly used neuromorphic datasets, such as DVSGesture, DVSCIFAR10, NCALTECH101, ES-ImageNet. Also, the neuromorphic dataset N-Omniglot for few-shot learning is also integrated into BrainCog.
This dataset contains 11 hand gestures from 29 subjects under 3 illumination conditions recorded using a DVS128.
This dataset converts 10,000 frame-based images in the CIFAR10 dataset into 10,000 event streams using a dynamic vision sensor.
The NCaltech101 dataset is captured by mounting the ATIS sensor on a motorized pan-tilt unit and having the sensor move while it views Caltech101 examples on an LCD monitor. The "Faces" class has been removed from N-Caltech101, leaving 100 object classes plus a background class
The dataset is converted with Omnidirectional Discrete Gradient (ODG) from 1,300,000 frame-based images in the ImageNet dataset into event-stream samples, which has 1000 categories.
This dataset contains 1,623 categories of handwritten characters, with only 20 samples per class. The dataset is acquired with the DVS acquisition platform to shoot videos (generated from the original Omniglot dataset) played on the monitor, and use the Robotic Process Automation (RPA) software to collect the data automatically.
You can easily use them in the braincog/datasets folder, taking DVSCIFAR10 as an example
