**Resume: **

**1.-** The tutorial is on distributed learning with MXNet by Alex Smolak and Arakan from Amazon.

**2.-** Take a picture of the slide with installation instructions as a reference.

**3.-** Raise your hand if you have issues during the installation process and someone will assist you.

**4.-** Introduction to the speakers Alex and Arakan who work for Amazon, but not in package delivery.

**5.-** Get started with MXNet on luong.mxnet.io.

**6.-** MXNet combines benefits of symbolic frameworks (Caffe, Keras) and imperative frameworks (PyTorch, TensorFlow).

**7.-** MXNet offers performance of symbolic frameworks and flexibility of imperative frameworks for deep learning.

**8.-** MXNet's NDArray handles multi-device execution on CPU, GPU, and more using non-locking, lazy evaluation.

**9.-** Device context in MXNet allows easy data movement between devices.

**10.-** MXNet doesn't allow incrementing individual elements in NDArrays to enforce parallelism and performance.

**11.-** MXNet's autograd allows computing gradients of dynamic graphs and running optimization.

**12.-** Example of defining and training a simple linear regression model in MXNet.

**13.-** Using MXNet's autograd to automatically compute gradients for optimization, even for dynamic graphs with control flow.

**14.-** Moving to multi-layer perceptrons, a type of neural network, as a more sophisticated example.

**15.-** Example code defining a multi-layer neural network architecture using MXNet's sequential layer API.

**16.-** The code allows flexibly defining networks in a procedural manner while getting symbolic framework performance.

**17.-** Discussion of activation functions, loss functions, and gradient-based optimization for training neural networks.

**18.-** Generating synthetic data and preparing it for training a neural network.

**19.-** Setting up the model, loss function, optimizer and fitting the model to the generated training data.

**20.-** Evaluating the trained model's predictions and loss on test data to assess performance.

**21.-** The MXNet code allows concisely defining models that can be automatically trained via gradient descent.

**22.-** More complex architectures like convolutional neural networks can be defined using a similar API.

**23.-** Pre-defined neural network architectures are also available in MXNet's model zoo for common tasks.

**24.-** MXNet can utilize multiple GPUs and machines for distributed training of large models.

**25.-** Performance comparisons showing MXNet's speed relative to other popular deep learning frameworks.

**26.-** Distributed key-value store enables easy parameter synchronization for distributed training.
