DL Notes: Advanced Gradient Descent

I researched the main optimization algorithms used for training artificial neural networks, implemented them from scratch in Python and compared them using animated visualizations.

DL Notes: Gradient descent

I describe the algorithm of gradient descent, which is used to adjust the weights of an ANN. A summary of information from different sources that I used when studying this topic.

Unconventional Data Analysis: extracting test bench results with Python

A practical example of how to use Python to analyze the results of an experimental test consisting of a sequence of stationary points

DL Notes: Feedforward Artificial Neural Networks

I share some notes about the basic math behind feed-forward Artificial Neural Networks (ANNs).

Moving average filters: the good and the bad

Moving averages are the go-to data smoothing trick for many people in Engineering and Data Analytics. However, they aren't always the best choice.

Computing the convection coefficient of a brake disc

I estimated the heat convection coefficient of a Formula SAE car. Let me share what I learned.

Estimating the working temperature of a brake disc

I used a lumped-body approach to approximate the properties of a brake disc and simulated its temperature increase after 100 braking maneuvers.

Brake system load distribution study - MATLAB approach

I studied the brake load distribution of a Formula car using a simple Matlab script. Let me show you how I did it.

3 keyboard macros to speed up your Simulink workflow

I configured my macro pad to improve the way I use Simulink. See how you can use custom shortcuts to save time.

Making a macro pad from scratch

I designed and built a QMK/VIAL macro pad from scratch. Let me tell you about the things I learned and useful resources I found as a beginner.

Fail better with an engineering mindset

Failure is often seen as a negative part of life we tend to avoid at all costs. And sometimes we become too good at it. I'll tell you how I learned to embrace it.

How I avoided typing long passwords - Use at your own risk!

I programmed an Arduino Pro Micro to write a long password every time I pressed a button. It helped me save a ton of time and I'm sharing how you can make one yourself - at your own risk!

Replacing MATLAB with Python - Part 3: Histograms and more data-indexing

I am sharing how I used Python to complete the second part of an example task originally done with MATLAB. I learned more about slicing dataframes and making histograms with two different libraries

Python

Replacing MATLAB with Python - Part 2: Formatting subplots and indexing data

I used Python to complete the first part of the task from my previous post in the series. I learned about formatting plots and indexing Pandas dataframes.

MATLAB

Using MATLAB and statistics to analyze raw vehicle data

I am sharing an example of the workflow I would follow for getting insights from real-world data using histograms and some very basic statistics.

Python

Replacing MATLAB with Python - Part 1

Stick with me in this series of posts if you want to see some examples of using Python for MATLAB users. I am not an expert, and the code I will share can probably be improved, but I think these practical examples can be useful for a beginner like me.
