[Verse 1] Three flavors of learning machines await your command Supervised knows the answers, teacher takes your hand Labels guide the process, input-output pairs Classification, regression, predictions it declares Unsupervised explores alone, no teacher's guiding light Clusters hidden patterns, makes the darkness bright Reinforcement learns through trial, rewards and punishment Agent meets environment, maximizing each event [Chorus] Neural networks firing, synapses made of code Convolutional sees the images, patterns they decode Recurrent remembers sequences, LSTM holds the past Transformers pay attention, revolution here at last Train and validate and test, three splits you must arrange Gradient descent optimizes, weights begin to change [Verse 2] Loss functions measure error, how far we've missed the mark Overfitting memorizes, regularization's spark Dropout kills connections, L2 penalty weighs Feature engineering crafts, representation learns its ways Precision counts true positives, recall finds every one F1 balances the two, AUC-ROC when we're done Confusion matrix tells the truth, predicted versus real [Chorus] Neural networks firing, synapses made of code Convolutional sees the images, patterns they decode Recurrent remembers sequences, LSTM holds the past Transformers pay attention, revolution here at last Train and validate and test, three splits you must arrange Gradient descent optimizes, weights begin to change [Bridge] Foundation models tower high, GPT and Claude Llama, Gemini, Mistral, capabilities unflawed Prompt engineering whispers secrets to the mind Few-shot learning demonstrates, chain of thought aligned RAG retrieves the knowledge, vectors in the space Embeddings find the neighbors, chunking sets the pace [Verse 3] Fine-tune or prompt or retrieve, three paths before you stand MLOps tracks experiments, versions from your hand Quantization shrinks the model, distillation makes it small Inference optimization, batching serves them all Guardrails watch for hallucinations, content filtering clean Human loops and A-B tests, the finest AI scene [Outro] From neurons to production, the CTO's domain Machine learning mastery, intelligence unchained
