DataSimple Guided Projects
Data science and learning how to code Python or really any coding language is unlike learning a traditional academic skill. Learning to write Python and build Machine or Deep Learning models is more like learning to paint in that we need to explore what is possible and how to follow your imagination in how we perform data analysis, pre-processing the data for our machine learning model, or architecting our deep learning model.
​
There are just so many possibilities out there that it's hard to know where to start. In this section, we have our free to use Python guided projects we practice data analysis with Pandas and Seaborn, machine learning with Sklearn and deep learning with Tensorflow.

LSTM Google Stock Prediction Part 1
Level 1, 18 minutes
In the first part of our LSTM stock prediction series we will start by getting our deep-learning neural network. In our Tensorflow model, we use the LSTM layer but either the SImpleRNN or GRU layers can easily be substituted in the Python code. This is a great opportunity to build intuition around the impact of each recurrent layer on our time series prediction.

Deep Learning with Tensorflow - NLP
Simple NLP Tensorflow Sarcasm Preidction
Level 1, 19 minutes
Simple Multiclass NLP Poem Classification
Level 2, 21 minutes
In this Deep Learning TensorFlow Guided Project, we will use the LSTM recurrent layer along with an embedding layer and dense fully connected layer in Python to predict if the news Headlines are sarcastic or not.
​
After we've done the essential NLP processing for deep learning we are ready to start building our architecture. We start with an embedding layer and next in our deep learning TensorFlow model we add a recurrent layer. You can use SimpleRNN, GRU, or LSTM layers but here we choose to use the LSTM layer.
In this simple TensorFlow multiclass prediction problem in Python we will be an NLP model and attempt to classify poems as Affection, Death, Environment, or Love. Poems are a very difficult NLP classification due to the abstract nature of the writing makes this a very difficult dataset to get a very high score. Our goal will be an accuracy of .50, which is normally very low but very difficult to achieve on Poem classification.
We will build our model today in the Sequential model in TensorFlow. The first layer in our model will be an Embedding layer. We will follow our embedding layer with a special type of dropout layer called Spatial Dropout and this drops each neuron by changing not a certain percentage of each layer. This allows some epochs to have more or less total neurons turned off. This type of dropout works for NLP problems.
Indian God Anime Name Generator
Level 4, 27 minutes
Follow along with this Free Guided TensorFlow project. In this free Python Project, we will use TensorFlow to build a deep learning model that will generate names. Here we will mix names of Indian Gods with Anime characters, why? Well because we wanted to have a little fun and be a little creative with our NLP TensorFlow Text Generation Project.
Name generation is actually easier than you would think, simply put your deep learning model that predicts the next character in a loop. The hard part is designing your deep learning model to be accurate but also a little crazy so we get some interesting generated names.
NLP Sentiment Prediction from TripAdvisor Reviews
Level 5, 31 minutes
Natural language projects are a little tricky and can be quite different than working with a typical dataset. We explore the data with WordCloud to understand and look for spelling errors. We then use Tensorflow to sequence and pad the data to get it ready for our neural network.

Simple Computer Vision Pneumoia Binary Prediction
Level 2, 22 minutes
Simple Multi Class Computer Vision Dessert Classification
Level 3, 24 minutes
In this simple TensorFlow Computer Vision Guided Project in Python we a convolution neural network or deep learning model to predict a binary classification problem and predict with an X-ray image containing a chest X-ray image with or without pneumonia.
Medical Image classification is a common and important type of computer vision problem In future projects we will explore the many various types of image preprocessing available on our images to enhance our predictions.
In this Simple Computer Vision guided project in TensorFlow using Python we will build a deep learning model to classify whether a dessert is an Apple Pie, French Toast, Donuts, or Cheesecake. In the near future, a company is building a machine to automate serving food to customers. The problem is that the Ai needs to be able to tell what food serving it is serving to customers.
Follow along in the Simple Python Guided Project Multiclass Computer Vision and classify which dessert is in the images. In the deep learning project, we will use the Sequential model in TensorFlow. To our Sequential model, we will add a set of two Convolutional layers. Convolutional layers tend to work well as pairs. Each convolution is followed with max-pooling layers and drop-out layers. We use max pooling because it was the same effect as sharpening images in a simple photo editor. These are following my dropout layers to prevent overfitting.
ImageDataGenerator TensorFlow Rock Paper Scissor
Level 4, 35 minutes
The hardest part of Computer Vision isn't the architecture is setting up the data for the model. Too many pictures are needed than can fit in your memory, TensorFlow's ImageDataGenerator allows you to connect your model with the folder that contain your images and allows you to pull images and augment new ones each epoch.
