Preparation of the seminar was very useful for me since it required me to make sure that I really understood how the networks function, and I (think I) finally got my head around back-propagation — more on that later. In this post,…

As everyone knows Machine learning studies computer algorithms for learning to do stuff. We might, for instance, be interested in learning to complete a task, or to make accurate predictions, or to behave intelligently. The learning that is being done is always based on some sort of observations or data, such as examples…direct experience, or instruction. So in general, machine learning is about learning to do better in the future based on…

What is Raspberry Pi?

Raspberry Pi is a small computer that costs between $5 and $35 but can function as a desktop computer or be used for additional functions, such as building smart devices. Originally, the Pi was intended for usage in schools as a method of increasing interest in computers among children and as a tool to teach them basic coding.…
