Generative AI by Andrew Ng (coursera-DeepLearning.AI) - Note

Link to coursera:  https://www.coursera.org/learn/generative-ai-for-everyone AI Supervised learning Labeling the output Performance depends on the amount of data Unsupervised learning Gnerative AI Reinforcement learning Large language models (LLM) Using the supervised learning to generate the text (learning from the repetitive sentences) LLM – > hundreds of billions of words – > that’s why the model can create a good performance Language is quite repetitive – > that is why it can generate the text LLM A new way to find information It can give you information Sometimes, it hallucinate Writing partner Finding information through LLM (but better to double checks) – perhaps web search might be better Generative AI General technology (for now) Useful for lots of things Work well with unstructured data (non-tubular data, for example, table form) Generating the image – > diffusion model by which labelling the text together with the image and repetitively do it step-by-step unt...

Google Data Analytics The process to do data analysis in order to drive the decision. Foundations Ask Ask the questions that we would like to be solved The question that would improve the current situation Ask question to define the problem Prepare Set the timeline and collecting the data Process Cleaning the data Checking the information Analyze Finding the pattern in data Finding the relationships and trends in data Share provide information of analysis Act make decision Use the analysis results Capstone Dimension of data analytics – there are three; pick one that is suit to the personality Machine learning – care about the model construction Statistic – using the number to describe the data Analytic – make sure either the model or interpretation makes sense Subject matter expert – a person who oversees whether the data analytic makes sense in the specific field. Life cycle of data analytic proposed by SAS -- Below is the information that I copied from Coursera to remind myself of th...
