AI in agriculture: fruit grading (Part 1)

Petamind A.I

During a meet up last month, a friend told me about the current project on a farm in New Zealand. They want to build a system to grade their fruits and AI is the technology they are looking for. It inspired me to write about how machine learning can help in solving such a problem. Fig 1: Apple grading The grading task Given an apple, we need to sort it to correct category in three available...

An example to Graph Convolutional Network

Petamind A.I

In my research, there are many problems involve networks of different types, e.g. social network, online-trading networks, crowd-sourcing, etc. I was so happy to find a new powerful tool for my research, the graph convolutional network, which applies deep learning on graph structures. Graph convolutional network (GCN) Graph convolutional network (Src: Thomas Kipf) There is currently no official...

A gentle demonstrate to Tensorflow’s graph and session

Petamind A.I

When starting Tensorflow (TF), many may find that the result cannot be obtained immediately. Rather, you must use a session or interactive session. TensorFlow uses a dataflow graph to represent your computation in terms of the dependencies between individual operations. This leads to a low-level programming model in which you first define the dataflow graph, then create a...

Convolutional Neural Network with CIFAR and Tensorflow (example)

Petamind A.I

Fig 1: A CNN sequence to classify handwritten digits (src: medium) In this article, we assume that you already understand the basic concepts of a convolutional neural network (CNN), e.g. one-hot coding, convolution, pooling, fully-connected layer, activation functions. If you are totally new to these terms, please find and read our other articles. The problem We will use Tensorflow to build a...

Petaminds – updates (Q3-2019)

Petamind A.I

As the number of readers increases, we think that it is time to improve Petaminds website to meet our objectives, i.e. content focused and readability. Currently, we are testing the new site design to meet the target. The theme will be comfortable and content-focused. Some improvements are:Use flat design theme Change the article clear typography Capital headings Increase the font sizes and...
