Forgetting Curve

A forgetting curve is a representation of memory retention over a period of time. Based on some early studies conducted by Ebbinghaus, it was shown that the forgetting curved follows a logarithmic curve. Given that there was no attempt to retain it. But how do you retain a memory. Memories

Complexity Theory

Complexity theory and related concepts emerged quite recently, towards the late 20th century. Complex means diversity, multiple concurrent interdependencies between different elements of a system. Human cells in itself are a very complex system. However they can self-organize and form groups. Create variations and give rise to even more complex

Robots that can feel

Our skin has many types of neurons that allow us to feel upon touch. They are receptors of different kinds that are triggered by different stimuli but activate the same way upon triggering. Thermoreceptors trigger on change in temperature. Nociceptors trigger on pain. Mechanoreceptors trigger on mechanical stress. These receptors

Thousand Brains Theory

Grid cells are special types of neurons that help us perceive position in a larger context. For example, to understand our position in the room we are sitting in. The cells themselves are arranged in a manner of a grid and fire based on our position. An array of such

Sparsely Activated Network

A deep learning network contains multiple learning nodes separated as layers and interconnected both within and across different layers to create a network. Typically deep learning models are trained by activating all nodes for each training input. Another way to train the network is to sparsely activate the network for

Equity Research and Newspaper

They both are similar in some aspects. – Both have an investigative component. There is a process of uncovering information that is not apparent or not in plain sight to perform equity research. Similar to how investigative journalism works. – The element of filtering signal from a lot of information

Structural Battery

Batteries have always been a limitation for electrifying devices and vehicles. “Today, batteries account for a substantial portion of the size and weight of most electronics. A smartphone is mostly a lithium-ion cell with some processors stuffed around it. Drones are limited in size by the batteries they can

Federated Learning

Federated Learning is a machine learning technique that trains algorithms with separate local samples and without exchanging them. This enables training of an algorithm using multiple devices. This is a huge plus from a data privacy and data security point of view. The basic principle is that the algorithm is

Brain Simulation

Brain simulation deals with creating a computer model of the brain. Such models can help in understanding diseases and reduce the need for animal experiments. The challenges in brain simulation are: Scale : The human brain contains about 86 billion neurons each with about 7000 connections. This pushes even the largest
