Explore how machine learning differs from classical programming, as data and target variables drive supervised, unsupervised, and reinforcement learning to build models for regression and classification.
Analyze loss functions for regression and classification, including mean squared error, mean absolute error, mean bias error, binary cross entropy, hinge loss, and multi-class cross entropy with activation choices.
Learn to implement a training loop from scratch: perform forward passes, compute squared losses, backpropagate gradients, update weights with an optimizer, and evaluate on test data.
Experiment with learning rate and the number of epochs to train the model. Observe results and identify stable, effective parameter combinations.
Explore how a confusion matrix describes binary classifier performance, detailing true positives and negatives, false positives and false negatives, and deriving metrics like accuracy, specificity, sensitivity, and precision.
Explore multiclass classification with the iris dataset, featuring three classes and four features, a 20% test split, and data preprocessing to float32.
Build a custom dataset class for our accustomed dataset in a multi-class exercise; you can implement it on your own or follow along with me.
Construct a simple multiclass classification network in PyTorch using two linear layers and a softmax activation, and practice implementing it within the multiclass net exercise.
Train the model over 100 epochs with a train loader, zero gradients, perform the forward pass, compute loss with the criterion, backpropagate, and apply the optimizer step while tracking losses.
Learn to debug a PyTorch CNN by performing a forward pass with a random 32-by-32, 3-channel input and inspecting outputs through conv, pooling, flatten, and dense layers.
Prepare audio data for classification by loading wav files, extracting class types from file names, and splitting them into train and test sets while generating spectrogram images.
PyTorch is a Python framework developed by Facebook to develop and deploy Deep Learning models. It is one of the most popular Deep Learning frameworks nowadays.
In this course you will learn everything that is needed for developing and applying Deep Learning models to your own data. All relevant fields like Regression, Classification, CNNs, RNNs, GANs, NLP, Recommender Systems, and many more are covered. Furthermore, state of the art models and architectures like Transformers, YOLOv7, or ChatGPT are presented.
It is important to me that you learn the underlying concepts as well as how to implement the techniques. You will be challenged to tackle problems on your own, before I present you my solution.
