2019.11.03(pm): How to install Anaconda and Jupyter Notebook
Anaconda Anaconda is a development platform that gathers open source for Python-based data analysis. Anaconda’s advanced package manager allows you to get the most out of Python. Another advantage of Anaconda is that the virtual environment manager can efficiently configure the development environment for each project. Download https://www.anaconda.com/download/ If you have anaconda installed, check the…

2019.11.02(pm): Bayes’s Theorem and MLE vs MAP
Bayes’s Theorem Called Bayes’s theorem or Bayes’s rule or Bayes’ law, this is a conditional probability equation (X2: model, X1: observation) Bayesian probabilities are probability transforms that allow the posterior probability to be calculated using prior and likelihoods. Bayesian probabilities mostly occur when classification and detection problems occur in image processing. In other words, Bayesian…

2019.10.09(pm): The concept of Perceptron
Let’s study artificial intelligence today ! Perceptron First, perceptron is a type of artificial neural network proposed by Frank Rosenblatt in 1957. It is an algorithm that produces one result from multiple inputs. Perceptron can easily be compared to neurons, the nerve cells that actually make up the brain. Neurons receive signals from the dendritic…

2019.10.03(pm): How to upload the fine dust data and graph your computer in realtime
Today we will draw a graph using the data from the PMS7003 fine dust sensor. When I compiled the code I uploaded last time, I suddenly got a compile error. While looking for the reason, I found that I did not update the Arduino / Genuino UNO board version. So I entered board manager and…

2019.09.21(pm): How to use fine dust sensor PMS7003
I post in almost two months. Today’s topic is the PMS7003, a fine dust sensor. Let’s take a look at the contents of the datasheet. PMS7003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles,…

2019.07.15.(pm): How to use IR sensor with ESP-WROOM-32
The ESP-WROOM-32 is a low-power communication module that combines Wi-Fi and Bluetooth. It has an appearance similar to the NodeMCU, and the specification is as follows. There is the pin out of ESP-WROOM-32. You can add it by using the unofficial board URL for use in the Arduino IDE environment, and install it in the…
