RNN, Recurrent Neural Network

A Recurrent Neural Network (RNN) is a class of artificial neural network that has memory or feedback loops that allow it to better recognize patterns in data. RNNs are an extension of regular artificial neural networks that add connections feeding the hidden layers of the neural network back into themselves - these are called recurrent connections. The recurrent connections provide a recurrent network with visibility of not just the current data sample it has been provided, but also it's previous hidden state. A recurrent network with a feedback loop can be visualized as multiple copies of a neural network, with the output of one serving as an input to the next. Unlike traditional neural networks, recurrent nets use their understanding of past events to process the input vector rather than starting from scratch every time. (© 2023 NVIDIA Corporation)

Overlap calculation in R

There are several R packages that can help you calculate the overlap between two density distributions. For example, `overlap`, `kerndwd`, `KernSmooth`, and `pracma`

Brownian Motion

Brownian motion is the random and erratic movement of small particles in a fluid or gas due to collisions with molecules in the surrounding medium. It was first observed and explained by Robert Brown in 1827, and is an important concept in the study of diffusion and stochastic processes. Who said this?

Python: Cell masks result analysis

It would be easy to count the result when we have only a few cells in an image. But once you got thousands of cells in an image and/or you got hundreds of repeats, the work would be tedious and laboring. But with the help of python, we can do more than sample counts and gray intensity calculation. We can apply more complicated techniques like Vironoi spacial calculation and Delaunay triangulation. I'll show how can we apply these two algorithms to finally determine whether cells may share boundaries or be physically contacted.

Python Machine Learning

Machine Learning is a subset of artificial intelligence that involves training algorithms to make predictions or decisions based on data. It involves learning from patterns and trends in data and using that knowledge to make predictions or decisions without being explicitly programmed. It is used in various fields like finance, healthcare, and marketing. Who said this?
