About Adjacency matrices were calculated for 40 cities using sensor data from https://doi.org/10.1038/s41598-019-51539-5 (ETH Zürich). I personally rented a Google Cloud server for roughly 500€ to calculate these matrices because we have so few of them in…
Intro to Language Processing Models The GPT (Generative Pre-trained Transformer) architecture, as its name implies, uses a Transformer architecture rather than an RNN (Recurrent Neural Network) as the foundation for ChatGPT-3. Due to their propensity…
Doom pornographers often enjoy posting terrifying tweets of the monstrous Jupiter sized derivatives market. The bubble boys love to post how any day now one of these banks with too much exposure to derivatives will…
Alright so you have a list of geocoordinates (for example maybe street sensors) and you want to create an adjacency matrix to feed into your PyTorch or Tensorflow GCN model such as the A3T-GCN. This…
The greatest misunderstanding on finance Twitter is central bank lingo. For the past decade and a half tweeps have been yelling that quantitative easing QE is going to cause hyperinflation and the end of the…
After the recent FTX collapse I want to return attention to what really is the underlying problem with the entire crypto ecosystem, namely the lack of real liquidity. This was brought on by the introduction…
I was never really a podcast sort of guy and I don’t even know if I ever opened the app on my iPhone before 2022. What did for me was finally turning down the knob…
A Macroscopic Fundamental Diagram, MFD, investigates the flow of traffic through a network of roads that span a spatial dimension. The relationship between the variables speed, flow, and density can be shown in three diagrams…
This example uses the K-Nearest Neighbour K-NN to connect several points and plotting those as a graph on a Plotly map. This is a quick and simple example that data scientists can use to illustrate a path(s)…
The following example uses OSMnx to generate the optimal path between two geocoordinates and between one and many points and plotting the path(s) on a Plotly map. This is a quick and simple example that…
