I have conducted a workshop on Tensorflow2.0 at Facebook Dev CIrcle. This mostly covers the importance of TensorFlow to implement deep neural networks. You can check the related demo at: https://github.com/rayyan17/Introduction-To-Tensor-Flow.git

1. Introduction To Tensorflow
A deep-learning framework
By
Rayyan Khalid

2. What is a Deep Learning Framework?
“An interface, library or a tool that allows us to build deep-learning model
easily and offers building blocks for designing, training, and validating deep
neural networks”

3. Building Blocks of a Deep NN
Feed-Forward
Back-Propagation
Computing
Loss

4. Building Blocks of a Deep NN cont.
● Input Data (X)
● Output (y)
● Hidden Layers
● Neuron
● Activation Functions
● Feed-Forward
● Loss Functions
● Optimizers
● Back-propagation

5. Choosing a Deep Learning Framework
● GitHub Activity
● Medium Articles
● arXiv Articles
● Books on Amazon
● Number of developers using it
● Google-Searches
● Online jobs posting

6. Deep Learning Framework Power Scores

7. Online Jobs Postings

8. Tensorflow is an undisputed champion

14. “Hello World” of Neural Network via Tensorflow
model = tf.keras.models.Sequential([tf.keras.layers.Dense(3, activation=tf.nn.tanh, input_shape=[1]),
tf.keras.layers.Dense(2, activation=tf.nn.tanh),
tf.keras.layers.Dense(1,)])
● Sequential: Represents a Feed-Forward-Network
● Dense: Represents a fully connected hidden layer
● Units: Represents the Neurons
Only need to pass in
the first layer
Output Layer

15. “Hello World” of Neural Network via Tensorflow
model.compile(optimizers="sgd", loss="mean_squared_error")
Model compile method deals with 3 major building blocks:
● Optimizer Functions
● Computing Loss
● Back Propagation
model.fit(x, y, epochs=800)
Model fit method represents your Training Cycle

17. Libraries for Tensorflow
● Tensorflow Hub: Provides many pre-trained models
● Hugging Face-Transformers: State of the art Natural Language Processing
for Tensorflow 2.0 and PyTorch
● Google-Colabs
● Tensorflow can be easily integrated with models built on other libraries,
like scikit-learn, gensim, Spacy
● Playground Provided by Tensorflow http://playground.tensorflow.org/

18. Coursera Specializations:
● Tensorflow in Practice Specialization
● Deep Learning Specialization
