You trained a Rock-Paper-Scissors model using only your own right hand, always held in the same position. A friend tries to use your model with their hand — and it barely works. What is the most likely reason? What actually happens during the “Training” process in the PicToBlox ML Environment? Which of the following are real-world applications of image classification Machine Learning? (Select ALL correct answers.) What is the correct order of steps when building an ML project in PicToBlox? Overfitting happens when a model performs perfectly on its training images but struggles to correctly classify new images it has never seen before. Your trained model analyses a hand gesture and gives these results: Rock — 8%, Paper — 85%, Scissors — 7%. What does this output tell you? In a PicToBlox ML image classifier, what is a “class”? In the PicToBlox ML Environment, collecting 20 varied images per class (different angles, distances, and lighting) produces a stronger model than collecting 5 identical images. What is the key difference between traditional programming and Machine Learning? 2.1 Assignment: PicToBlox — ML: Train Your Own Model 1.1 Quiz: Inside the CPU: How Processing Works During which step of the Fetch-Decode-Execute cycle does the Control Unit work out what an instruction actually means? What does hyper-threading allow a CPU to do? A CPU is advertised as running at 4.2 GHz. What does this number tell you? Cache memory is built directly inside the CPU chip and is faster to access than the computer’s main RAM. Which of the following are components found INSIDE a CPU? (Select ALL correct answers.) A CPU with a higher clock speed will always outperform a CPU with a lower clock speed, regardless of any other factors. A CPU with a higher clock speed will always outperform a CPU with a lower clock speed, regardless of any other factors. Which component inside the CPU is responsible for performing all arithmetic calculations and logical comparisons? What is the correct order of the Fetch-Decode-Execute cycle? What does the abbreviation “CPU” stand for? 1.2 Assignment: Binary Numbers & How Computers Think 1.2 Quiz: Binary Numbers & How Computers Think 1.1 Assignment: Inside the CPU: How Processing Works 1.1 Inside the CPU: How Processing Works 1.1 Quiz: What is Coding? Meet PicToBlox Junior! In PicToBlox Junior, how do you add a block to your program? Which of these is a real-life example of something that follows coded instructions? A program is just ONE instruction given to the computer. Why is it important to give the computer CLEAR and EXACT instructions? Blog
