What can you learn from machine learning?
Implementing a machine learning algorithm in code can teach you a lot about the algorithm and how it works.
Why are custom implementations of algorithms required for production systems?
Production Systems: Custom implementations of algorithms are typically required for production systems because of the changes that need to be made to the algorithm for efficiency and efficacy reasons. Better, faster, less resource intensive results ultimately can lead to lower costs and greater revenue in business, and implementing algorithms by hand help you develop the skills to deliver these solutions.
What is the first step in mastering an algorithm?
Mastery: Implementation of an algorithm is the first step towards mastering the algorithm. You are forced to understand the algorithm intimately when you implement it. You are also creating your own laboratory for tinkering to help you internalize the computation it performs over time, such as by debugging and adding measures for assessing the running process.
How does machine learning help you?
Implementing a machine learning algorithm will give you a deep and practical appreciation for how the algorithm works. This knowledge can also help you to internalize the mathematical description of the algorithm by thinking of the vectors and matrices as arrays and the computational intuitions for the transformations on those structures.
How to research an algorithm?
Research Algorithm: Locate papers, books, websites, libraries and any other descriptions of the algorithm you can read and learn from. Although, you ideally want to have one keystone description of the algorithm from which to work, you will want to have multiple perspectives on the algorithm. This is useful because the multiple perspectives will help you to internalize the algorithm description faster and overcome roadblocks from any ambiguities or assumptions made in the description (there are always ambiguities in algorithm descriptions).
What are practical skills?
Practical Skills. You are developing valuable skills when you implement machine learning algorithms by hand. Skills such as mastery of the algorithm, skills that can help in the development of production systems and skills that can be used for classical research in the field.
Why is a standard library important?
Using a standard library can reduce the likelihood of having bugs in the algorithm implementation.
Why break an algorithm into chunks?
Breaking the algorithm up into chunks like this makes it easier to learn. Basically I’ve outlined the algorithm with pseudocode, and now I can go back and fill in the fine details. Here’s a picture of my notes for the second step, which is the dot product of the weights and inputs:
What is a perceptron?
The single layer Perceptron is the most basic neural network. It’s typically used for binary classification problems (1 or 0, “yes” or “no”). It’s a linear classifier, so it can only really be used when there’s a linear decision boundary.
Is it rewarding to write an algorithm?
Writing an algorithm from scratch can be a very rewarding experience. It’s a great way to gain a deeper understanding of the model, while building an impressive portfolio project at the same time.
Can you write an algorithm from scratch?
Absolutely not. Some algorithms are just more complicated than others, so start with something simple, such as the single layer Perceptron. I'll walk you through a 6-step process to write algorithms from scratch, using the Perceptron as a case-study.
When you validate against an existing implementation of a model, do you need to be very aware of the inputs to?
This brings up another important point. When you validate against an existing implementation of a model, you need to be very aware of the inputs to the model. You should never blindly use a model, always question your assumptions, and exactly what each input means.
Can you implement an algorithm from a machine learning library?
You can showcase it to potential employers. It’s one thing to show that you can implement an algorithm from a machine learning library, but it’s even more impressive if you can implement it yourself from scratch.
Is it better to use textbooks or YouTube videos?
better with video. Personally, I like to bounce around and use various types of sources. For the mathematical details, textbooks do a great job, but for more practical examples, I prefer blog posts and YouTube videos.
What is the key type of information you are interested in when researching a machine learning algorithm?
Usage heuristics and best practices are probably the key type of information you are interested in when researching a machine learning algorithm for practical and applied purposes. Usage heuristic sources provide an expert description for how to use a given machine learning algorithm in practice.
Why are seminal sources important?
Seminal sources are good for getting inside the head of the original author or describer of a machine learning algorithm and teasing out the intent of algorithm parameters and processes. These sources are almost always academic and theoretical and only occasionally include useful usage information.
What is the heart of machine learning?
Often the heart of a given machine learning algorithm is an optimization process that is stochastic, meaning it has elements of randomness. As such, this makes machine learning algorithms more difficult to analyze and to make hard judgements about best and worst performance.
