Learning Tensorflow Step by Step:: Concepts, Examples & Applications

Tutorials for TensorFlow

• Conv_Basic_with_TensorFlow: Start with building blocks of Deep Neural Networks and Slowly Build and Understand Convolutional Neural Network. Below is an example of how Conv and Max Pool layer understand features, training images are from MNIST Fashion Data-Set.
  

• im_generator: Learn to Preprocess Image Using Keras, 'flow_from_directory' and augemntation on the fly.

• Multi_Class: Moving from binary classification to multi-class classification.

• Transfer_Learning: Using VGG16 weights to train a model. 2800 images of cats and dogs are used for training and 600 images for validation.

• NLP_Embedding: Moving on from computer vision tasks, here we discuss classifying IMDB movie reviews and visualizng how embedding can help cluster words (positive & negative).

• NLP_LSTM_Glove: Using pretrained Glove to classify tweets of positve sentiments from the negative one. Dataset - 1.6M Tweets

• Time_SeriesW#: Deal with time series data, starting from simple linear regression to RNN, LSTM, 1D Convolution were used to build deep networks. Example of predicting minimum temperature of Melbourne is shown below--

• TFDataIntro.ipynb:* Introducing TF Dataset API and how to use them effectively to build efficient and fast data analysis pipeline. More details in TDS.

• cassava-classification.ipynb: Cassava leaf disease classification competetion in Kaggle. The notebook here is the same one used for submission in the competetion.

• detectpneumonia...ipynb Pneumonia detection using TensorFlow dataset API. The dataset is available in Kaggle. Many important comcepts such as standardization of images, class imbalance, roc curve as performance metric were influenced by DeepLearning.ai course.

• ViT_TensorFlow How to implement Vision Transformer using TensorFlow2.0 from scratch and detail understanding of how attention mechanism actually works. More details on TDS. .

• TF-Proba/Bayesian_uncertainty.ipynb Two types of uncertainties Aleatoric and Epistemic and how we can use Bayesian Neural Net for estimating uncertainties. Example using real weather data and TensorFlow Probability Library. More on TDS.
