Progress updates and sudden news
Sudden news: Have to go to the US for approximately 2 weeks, so any previously planned progress will probably be impeded. US trip: 23 Dec to 6 Jan (15 days) For the past few days: most work is focused on Andrew Ng's Machine Learning Course. So far, the area of Machine Learning focused on is "Supervised Learning", which (I guess) arguably is the part which contains simpler algorithms as opposed to "Unsupervised Learning". There was a heavy emphasis on regression, especially linear regression, and the associated cost function. The cost function is denoted as J( Θ), where Θ is a vector of the associated features (or factors affecting) of the function. The purpose of the cost function is to measure how much the data points deviates from the line of regression. To determine the equation of the regression line, also called the hypothesis function h( Θ ), one of the methods used is to use "Gradient Descent", there was a lot of details describing t...
