Machine learning has had a huge impact on the world over the last few decades, and its popularity seems to be ever-growing. Recently, more and more people have familiarised themselves with machine learning subfields, like neural networks, which are networks inspired by the human brain. In this article, Python code for a simple neural network that classifies 1x3 vectors with 10 as the first element, will be presented.

Step 1: Import NumPy, Scikit-learn and Matplotlib

import numpy as np
from sklearn.preprocessing import MinMaxScaler
import matplotlib.pyplot as plt

We will be using three packages for this project. NumPy will be used for creating vectors and matrices, as well as mathematical operations. Scikit-learn will be used for scaling the data, and Matplotlib will be used for plotting the error development during the training of the neural network. …

MACHINE LEARNING

Neural network algorithms learn from data. This happens through training, which usually includes multiple iterations of forward and backward pass. A forward pass is done to predict the output based on the given input data, while a backward pass is used to minimize an error function and make the algorithm predict better during the next iteration.

NATURAL LANGUAGE PROCESSING

GPT-3 is a new tool, based on a machine-learning algorithm, which is used to predict text. It is released by OpenAI, where Elon Musk and Sam Altman are two of the founders, and both of them have been outspoken about the possibility of artificial general intelligence (AGI), as well as the opportunities and dangers that it may present our society with. Therefore, they wanted to create a company that is developing artificial intelligence in a responsible manner. …

MACHINE LEARNING

Many machine learning projects involve training an algorithm on massive amounts of data, and hence requires a lot of computing power. This computing power is typically tied to the number and quality of the processing units, such as the central processing unit (CPU) or the graphics processing unit (GPU). The performance can also be greatly affected by the number of cores in the processing units. A core is a unit that can perform computing operations, and the more cores a CPU or GPU has, the more operations it can run in parallel. …

STARTUP IDEAS

1. Wash and dry dishes in one movement

Washing the dishes takes up a lot of time, makes your hands greasy, and does not always yield a perfect result. For most of today’s dishwashers to work, you will have to clean up the dishes before putting them into the dishwasher. Then the dishwasher will spend multiple hours washing the dishes before you pick them out and place them in your dish cabinet.

To solve these problems, a startup should build a dishwasher that washes the dishes instantly. Think about automatic car wash machines where you drive your car into a garage, water and soap are applied, multiple brushes make the car clean, and then finally the car is dried before you can drive out of the garage. Now, imagine a similar solution for dishes. You place a plate into something that looks a lot like a slot toaster, and then 5 seconds later the plate pops up clean and dry, and can be placed into the dish cabinet right away. …

MACHINE LEARNING ALGEBRA

Algebra is an important element of mathematics and has a lot of practical applications. Among other things, it plays a crucial role in the economy, quantum computing, and machine learning. For the latter one, matrices and vectors are important, while the popular Python framework PyTorch uses tensor-based operations. Despite their similarities, a tensor is neither a matrix nor a vector, contrary to what many people think.

A matrix is a grid of m x n numbers surrounded by square brackets. Here, m is the number of rows and n is the number of columns. Mathematical operations can be performed on matrices, such as e.g. …

Startup Ideas Tips

I have wanted to learn machine learning for quite some time now. As many people do when they want to learn something new I did multiple courses, scrolled through Youtube for explanatory videos, and read about different elements of machine learning on the internet. Although all of that gave me a great overview and a basic understanding of what machine learning is, I realized that I didn’t acquire the skills necessary to make something useful by myself.

I needed to get hands-on experience with relevant projects to make the newly acquired knowledge useful. I could have tried to do a competition on Kaggle or found a clean dataset to work with, but I didn’t want to do something someone else had done before. I believe that you learn most when you try to challenge yourself to accomplish something no one else has done. …

Legendary entrepreneur and VC Peter Thiel has for a long time been advocating big, revolutionary ideas. In his book, Zero to One, he introduces the concept of secrets. Secrets are described as non-obvious problems and should be the basis for startups, according to Thiel. For a short summary of Zero to One, including the most important takeaways, see the article below.

Secrets are often divided into two groups:

1. Secrets about people
2. Secrets of nature

People secrets are unknown characteristics about people. These are often unknown either because the person isn’t able to see the secret or because he or she is trying to hide it from others. Due to the non-obvious nature of people secrets, the best place to look for them is where no one else is looking. All people have different backgrounds and knowledge, and will most often think in terms of what they know. There are, however, many fields that matter, but haven’t been standardized yet. One such field is nutrition, which is important to all people, but very few people study. …
