in the kaggle intermediate machine learning course. And I could not remember the three ways I could deal with Categorical variables. I remember that I could delete them. And I remembered the name one hot-encoding. But, no matter how hard I tried I could not remember ordinal encoding.

Ordinal encoding is where you turn the categorial variable values into numbers. Its used when there is a what is it called a order to the values.

One hot encoding is best used for a small amount of values. Its where you turn the categorical vales into numbers. You add a column for each value of the categorical variable.

I tried to remember the definitions for ordinal encoding and one-hot encoding from memory. I seem to go the definitions about right.

I want to practice practice machine learning so I can make something with it. That is the who point of learning programming so I can make a program. At least I think it is.

Since the first time I went through it I could not remember how to do anything. So I needed to go through the course again.

Not long ago I watched some videos from a Stanford machine learning course. It was fun watching the videos but, I was lost. I did not understand the math.

In the book the secret life of programs it seemed that to do machine learning you needed to know a lot of math so I want to learn more math. I know more about math than I did several years ago but, I have a long way to go to get good at math. I will try.

I first read Remember it in 2018. Before that time I was not aware of Memory competitions. When I read the book back then I had trouble remember the see, link, go technique.

Its where you turn say a name into a picture, link it to a something you already know and go. Go is Sensory overload, Grotesque absurdity, moveable attributes.

Anyway after I finished reading Remember it in 2018 I had the intention of practicing memory techniques everyday. That did not happen. I did try using the techniques in the book to memorize a grocery list and names. That is about it.

This year after reading remember it I made a Person, action object list for the numbers 00-99 and a list of person, action, object for playing cards. I even practiced remembering the playing card list. I still have a lot of work to do. At least I am trying.

Two websites that I learned about from Remember it are art of memory and memory league. Art of memory had memory techniques.

And memory league has competitions I can compete in online. I thought how cool. So I can practice the memory techniques.

So hopefully I will get good at the memory techniques I learned in remember it.

learn how to make machine learning programs and I also want to learn about ethical hacking. I have tried to learn how to program for years. Since the first day I could a computer really. With no success. So I figure I can’t learn both machine learning and ethical hacking at the same time or maybe I can.

Well anyway I want to learn how to make machine learning programs. I figure I want to get good at machine learning and then I will learn ethical hacking. Or maybe I will keep trying to learn machine learning and ethical hacking at the same time.

I just want to learn something that will be a useful skill.
