Financial Reporting - Corporate Governance

Corporate Governance


Let’s start with some more recapping from last time:

  • The gearing ratio measures what proportion of a business is funded by borrowing

  • Depreciation does not count as a cash expense

  • Current assets are usually only held during one operating cycle, so they are expected to be sold within a year

Algorithms - Analysis of Algorithms

Analysis of Algorithms


There are 2 ways of doing this:

  • Inspecting pseudo code.  This is the analytical approach

  • Implement the algorithm and time it. This is the experimental approach


The analytical approach is usually preferred because:

Algorithms - Complexity

Complexity


Note: You really need to read the algorithms text book chapters 1 to 3 as well as reading these notes!

Second note: This will probably be quite short as I'm cutting out all the exposition from the notes and just including the important information.

Machine Learning – Entropy

Entropy is a probability based measure.

Now, lets have a quick example:

Machine Learning – Decision Trees

I bet you thought that was going to say Decision Boundaries again :D – well… that is… if you’ve read the first 4 Machine Learning posts ;)

Nope, this time is Decision Trees, which are very similar to trees in programming – aka Binary Trees.

Maths / Logic and Modelling – CNF

This is going to be the first post I'm going to write that is valid for BOTH year 1 and year 2. Just in case you get confused as to who should be reading it ;)

CNF is short for Conjunctive Normal Form. A formula is in CNF if it is True (T) or False ( _|_ ) or a conjunction of disjunctions:

Logic and Modelling – Polarity

No, this a not a post about the North and South pole ;)
