Now that the very first offering of PIC16B at UCLA is over, let’s reflect on what we, i.e., Alice and I, had worked and achieved together for the project, which is one of the most crucial components of the class. Project Overview: Colorization has a variety of applications in recreational and historical context. It transforms how we see and perceive photos which helps us tremendously in visual...

Are you confident with your ability to spot fake news? Do you know that seven in ten Americans overestimate their ability in identifying false headlines? Well, one should even wonder whether what I just claimed is verifiable and truthful or not.

In this blog post, we will study and create a spectral clustering algorithm which is basically used in exploratory data analysis to divide data points into different group where each group has their own characteristics/features. Notation In all the math below: Boldface capital letters like \(\mathbf{A}\) refer to matrices (2d arrays of numbers). Boldface lowercase letters like \(\mathbf...

In this assignment, we will be working with the NOAA climate data set to create some interesting visualizations. \(\S 1.\) Database There are three tables that we need to create within a database which are stations, countries, and temperatures. In order to generate a database, we need the help from sqlite3 which is a module that allows us to conveniently create and query databases. import sql...

In this very first post of PIC16B, I will demonstrate how to visualize the Palmer Penguins data set with the help of panda and seaborn which is a data visualization library based on matplotlib. Data Preparation First, we need to load the data set using read_csv() function from panda. import pandas as pd url = "https://raw.githubusercontent.com/PhilChodrow/PIC16B/master/datasets/palmer_penguin...
