Motivation and Machine Learning (Lesson 3) Part 1

Image
One of Machine Learning's most important process is model training. This is the process in which we transform data into trained ML models, hence its importance.  Before we train our model, it  is important we master data handling,  data preparation and data management because proper data is is a key ingredient for successful ML models. Issues like high bias, classification problems, poor performance are often related to problems on the data itself. So it's really crucial to feed proper, accurate, clean and high quality data into our machine learning models for training. Model training is a core process in Machine learning that allows us to build, train and check the quality of ML models.  Data wrangling is the process through which we clean data, restructure it and enrich the data to transform it into a format that is much more suitable for the training process of Machine Learning Algorithms. ********* Managing data for machine learning work on Azure needs us to understand 2

Days 10-12 2.25(learning functions):  ML is a process for learning functions and models are specific representations of those functions gotten from training data. Y=f(x) + e Where y is output, x is input, f is function and e is the irreducible error. ML algorithms learn from a target function F that describes the mapping. 2.26: parametric and non-parametric algorithms Based on the size and structure of a function ML algorithms try to learn, they can be classified into parametric and non-parametric. parametric: these algorithms maps into a known functional form. It starts by assuming a  form, then learning its coefficients based on that form. non parametric: these algorithms do not make assumptions regarding the mapping between input and output data, so they are free to learn any functional form from the data. Benefits of parametric functions: simpler to understand, faster, easy interpretation and requires less training data. Disadvantages; it's highly constrained, limited com

Day 5 Learnt about Tabular Data - data simply arranged in tabular format like in an Excel spreadsheet with rows, columns and cells where they intersect. Rows describe a single observation, product or entity Columns describe the properties or features of the item. Column values can be continuous (countable numeric values that can take any value) or discrete(categorical) values which have a limited range and needs to be converted. Cells represent single value in row and column intersection. In machine learning we ultimately work with numbers specifically vectors. So everything that isn't numbers like the categorical variables, text, pictures, videos, audio inputs are eventually converted to array of numbers. Day 6 Revision - 2.8 Scaling Data and 2.9 Encoding categorical data The point of scaling Data is transforming it to fit within some range or scale say 0 - 1 or 1-100. It doesn't affect the algorithms because every value is scaled same way. It can speed up the training process

  Been a long while here. Been up and running as usual, working my butt off to make a living and see how I can contribute to making the world a better place the little way I can.  So a lot has happened since the last time I wrote here and i am grateful for everything. I got selected for the Phase 1 of a Machine Learning challenge course sponsored by Microsoft in collaboration with Udacity and it's been great so far. My network of international friends and acquaintances really grew by a significant percentage and I have had the opportunity to share some of m knowledge and skills with lots of people around the world as a student leader. Machine Learning is really awesome stuff that is poised to create a lot of opportunities in today's world while topping over a lot of traditional/manual processes. And I think you should pay attention it. That's what i have been doing. And I ave been thinking of a way to connect ML/AI to Motivating and inspiring the best they can be. How can

Derive Joy From Every Win

I am really inspired and excited to be writing this and I think the inspiration to write it is coming at a very good time. If you pay close attention to the people around you and to happenings around the world, you will find that a couple of people are unhappy. Statistics show that about 1 in 4 people are mentally depressed. Why are they unhappy? They are thinking of problems, thinking of how they will get to where they desire to be, bothered about the things that they are yet to have, the kinda relationships they dream of and etcetera. No one is expected to be happy all the time, however one needs to at least feel good most of the time regardless how things may seem. So how can these unhappy people (who are constantly bothered about the things they desire) learn to be happy? I have a simple tip today which I believe will go a long way to help them. If you are already feeling good about yourself most of the time, you can share this tip with someone who you know is mostly down and adopt

What Happened To Victor Pride of Bold and Determined?

So after so many months without visiting his blog, I tried to visit boldanddetermined.com for some fired up articles only to get a surprise.. that the blog has been permanently closed and then there's podcast following from Vic Pride (now Brother Nicholas) claiming that He's now Born again and has given his life to Jesus Christ. I didn't know how to feel. Whether it's good news or bad news will ultimately be up to us, but I just think I should share my thoughts about it here. But before that a brief background story. Victor Pride has been running the motivational blog bold and determined since 2011 and he has actually inspired and motivated a lot of young men and women to break out lazy attitudes/habits to live the life of their dreams.  Even though, I never really agreed with quite a number of his ideas about God, religion, the government, women etc, I still saw the truth in some of the things he said. And he had a very unique way of writing with gives you that adrenal

How To Show People You Value Them

Hi guys, Been a while! Lots of things happening around the world right now and nobody even knows what will happen next! There are ongoing protests right now over racism and police brutality and Covid 19 is still making headlines. These are really tough times for everyone as economies are struggling and social distancing is becoming a norm. Despite these present realities, you don't have to alienate yourself from people or keep too far away from them because of social distancing. Right now more than ever, it is very important you show people that they matter to you and you value their relationship and friendship. Here are six tips you can take advantage of: 1. Engage them from time to time We are all busy, that's true! I agree to that statement even though (on a lighter note) I think most of us are busy doing nothing.. haha. However, no matter how busy we are or think we are, we must discipline ourselves to make out time to engage with the people we care about. We all have 24 hr
