1. DEEP LEARNING Building an Image Classification Model Jennifer Kwentoh @jennifazor
2. IF you re new to deep learning…… Welcome You: Me:
3. Before we get to the Onion Machine learning Neural Networks Deep Learning Convolutional Neural Network Building an Image Classification Model
4. Machine learning is not bunch of IF Statements To teach a machine to recognize a face, we would have to hard code functions of every detail of a face Whereas in machine learning we define the outcome (the face) and the program learns how to get to the output Standard programming Machine Learning
5. Let’s take a step back to Machine Learning Supervised Learning: we give the machine a structured label (outcome) Unsupervised learning: There is no structured label. Reinforcement Learning: we use a trial and error technique
6. The Human Brain
7. Artificial Neural Networks An interconnected group of nodes inspired the biological brain. An artificial neuron can receive a signal process it and then signal additional artificial neurons connected to it.
8. Deep Learning is the subset of machine learning that has networks capable of learning unsupervised from unstructured and unlabeled data Deep learning is neural network of many layers It needs a lot of computing power (GPUs or TPUs)
9. Artificial Neural Networks & Deep Learning Convolutional Neural Network are used to classify images Facebook adopts CNN for photo tagging
10. CNN
11. Note: Deep Learning needs a good training dataset to classify well. IMAGE CLASSIFICATION EXAMPLE Google iO|18 Diagnosing Diabetic Retinopathy
12. Take a break! Have a chit-chat with your neighbor Touch up your makeup We will be back in 5
13. Set-up our Environment • GPUs Vs CPUs • Jupyter Notebook • Keras, Tensorflow • Data Sets: Kaggle.com • Python
14. GPU platforms you can use • Paperspace • Crestle • AWS • Google Cloud Platform • Azure Cloud
15. Goto https://colab.research.google.com • Let’s get started with coding
