1) ROCK SCISSOR PAPER WITH ML AND MEDIAPIPE

(IRONHACK DATA ANALITICS BOOTCAMP'S FINAL PROJECT)

Play rock scissor paper with computer vision

I trained ML classification alghorithms that recognizes rock, scissor or paper through the camera. By showing your hand-move to the camera, it will recognize wich your current move.

3) GRADIENT DESCENT VISUALIZATION WITH TOUCHDESIGNER

It shows how the coefficient and the intercepts adjusts through the epochs

You can choose a few parameters (number of samples, slope, learning rate, initial weights... ) and whatch how weights correct themselves. It shows:

• A 2D plot with the samples, the OLS regressione line, the errors squared and the predicted values
• The values updating
• The loss function
• The current gradient descente and global minima in 2D and 3D

4) PREDICTING SEXUAL DISCRIMINATION

I use Harvard University Implictit Association Test data to spot predictors of sexual discrimiation (exploratory analysis and machine learning). The fig. shows variables correlated (OLS exploratory regression) with implicit discrimination.

5) SCATTERPLOT GENERATOR WITH TOUCHDESIGNER

The projcet contains a scatterplot generator in a touchdesigner file. Upload a csv file, write down the x and y variables, and it's done (no code needed).

Plus, it contains many more features, good both for data visualization and data exploration.
