Abstract

Abstract –
Computer Vision has lots of applications including medical imaging, autonomous
vehicles, industrial inspection and augmented reality. Use of Deep Learning for
computer Vision can be categorized into multiple categories for both images and
videos – Classification, detection, segmentation & generation.
Having worked in Deep Learning with a focus on Computer Vision have come
across various challenges and learned best practices over a period
experimenting with cutting edge ideas. This workshop is for Data Scientists &
Computer Vision Engineers whose focus is deep learning. We will cover state of
the art architectures for Image Classification, Image Segmentation best practices in training and tuning deep neural networks. It will be hands on session in PyTorch v1.0.

The workshop takes a structured approach. First it covers basic techniques in
image processing and python for handling images and building Pytorch data
loaders. Introduce CNN based architectures for Image Classification (Resnet). Discuss ideas from cutting edge papers on Computer Vision and implement hands on in class best practices in on Image Classification and Semantic Segmentation architecture. Discuss how to train and tune deep neural networks.

Outline

Total Duration of Workshop – 6 hours
Outline-
Part I – Duration: 1.5 hours
1. Introduction to Image Processing in open CV – Solve an end to end Computer Vision problem using OpenCV and discuss hands on concepts of Image Processing, Masking, Morphology operations, Contour Detection, Edge Detection etc
2. Introducing PyTorch – Tensor Operations and manipulations, Automatic Differentiation, Torch Vision and Data Loaders in PyTorch v1.0
3. Project 1 – creating data loaders in pytorch v.10 for Image Classification and Semantic Segmentation
Part II – Duration: 3 hours
1. Creating a Neural Network in PyTorch using torch.nn module, writing a training loop, optimizers and loss function.
2. CNN – Hands on implementation of CNN architecture (Resnet) for image classification, Data Augmentation.
3. Project 2– Time Series problem solving through Image Classification
4. Autoencoders – Hads on Implementation of Convolution Autoencoders
5. Semantic Segmentation – Discuss ideas of FCN paper- Skip Connections, Deconvolution, Removal of fully connected layers
6. Implement U-Net based architecture in PyTorch v1.0
7. Project 3– Semantic Segmentation to generate mask on medical image dataset using U-Net architecture

Part III – Duration: 1.5 hours
1. Practical advice and best practice to train deep neural network
2. Tuning hyperparameters – discriminative Learning rate, one cycle policy, mixed precision etc. Show ipython notebooks in detail as to how to implement them.
3. Practical implementation of best practices in training deep neural networks – Initialization, batchnorm, early stopping, minibatch training, callbacks and hooks in training loop
4. Revisit above hands on projects and experiment with the best practices learnt in the class

Target Audience –
• Computer Vision Engineers
• ML/Deep Learning Engineers/Architects
• Data Scientist – who wants to pick up Computer Vision
• Deep Learning practitioners in general

    Hello Usha,

    Edit this proposal and resubmit with the following details:

    1. Duration of the workshop. If you are unsure about the exact duration, you can speculatively put it down as either 4 hours or 6 hours for now.
    2. Background knowledge required to participate in the workshop. What concepts/technologies should participants be familiar with in order to attend the workshop.
    3. Target audience: who should attend the workshop? Specify personas rather than mentioning beginner or advanced level audiences. Ensure that the workshop caters to one specific audience segment only.
    4. Who should NOT attend this workshop.
    5. Why attend this workshop? What will participants learn from attending this workshop? How will they benefit?
    6. Detailed workshop plan. Give us a break-up of the different sections of the workshop and what content will be covered in each section.
    7. Requirements. What software and other tech should participants install on their laptops before coming to this workshop? Should participants carry laptops with specific configurations on their machines?

    The above details should be added to this proposal by or before 24 May so that we can review the details and close on the decision.

    Besides the above, please respond to the following comments:

    1. Have you conducted this workshop before? If yes, share details.
    2. The preview video has only one instructor whereas two instructors are mentioned here. We need to see a preview video with both instructors.
    3. The preview video refers to this proposal as a talk at some places and as a workshop at other places. We are assuming this is a workshop proposal only.
