    This is sixth and final capstone project in the series of the projects listed in Udacity- Machine Learning Nano Degree Program. While deep learning has successfully driven fundamental progress in natural language processing and image processing, one pertaining question is whether the technique will equally be successful to beat other models in the classical statistics and machine learning areas to yield the new state-of-the-art methodology pandas - How can I download stock price data with Python I found the easiest to be the new SimFin Python API which lets you download stock-prices and fundamental data, save it to disk, and load it into Pandas DataFrames with only a few lines of code.

    They have also made several tutorials on how to use their data with other libraries such as statsmodels, scikit-learn, TensorFlow, etc. Price prediction is extremely crucial to most trading firms. People have been using various prediction techniques for many years. Jul 22, I would like to continue the topic on stock price prediction and to endow the recurrent neural network that I have built in Part 1 with the capability of responding to multiple stocks.

    You have very limited features for each day, namely the opening price of the stock for that day, closing price, the highest price of the stock, and the lowest price of the stock. GitHub Gist: instantly share code, notes, and snippets.

    This is important in our case because the previous price of a stock is crucial in predicting its future price. In this tutorial, we'll build a Python deep learning model that will predict the future view raw stock1.

    Use NLP to predict stock price movement associated with news. Updated on May 1, ; Python Stock Market Analysis and Prediction is the project on technical analysis, visualization and prediction using data provided by Google Finance. Pick any company you'd like. This is a fun exercise to learn about data Stock market prediction is the act of trying to determine the future value of a Using python code, I import library, first I try to for SVM on train dataset and then I.

    In addition, we will be using Keras 2. Note that if pandas DataReader does not work, you can use the yfinance package. You can use the symbols of other assets, e. The data is limited to the timeframe between and the current date. So when you execute the code, the results will show a more significant period as in this tutorial.

    When you work with time-series data, visually viewing the data in a line plot is the primary way to do this. Then we predict the price of the next day based on the last 50 days of market prices. Before we can begin with the training of the NN, we need to split the data into separate test sets for training and validation and ensure that it is in the right shape.

    Therefore, we also have to decide on the neural network architecture before bringing our data in the right shape. During the training process, the neural network processes the mini-batch one by one and creates a separate forecast for each mini-batch. The illustration below shows the shape of the data: Sample dataset for time series forecasting divided into several train batches. Neural networks learn in an iterative process.

    In this process, the algorithm reduces the prediction errors by adjusting connection strength between the neurons weights. During training, the model compares the predictions with the ground truth and calculates the training error to minimize it over time. Each contains a series of quotes for 50 dates. Be aware that numbers depend on the timeframe and will vary depending on when you execute the code.

    Step 5 Designing the Model Architecture Before we can train the model, we first need to decide on the architecture of the model. Above all, the architecture comprises the type and number of layers and the number of neurons in each layer. Selecting the correct number of layers from the start is difficult or even impossible.

    A common approach is to try different architectures and find out what works best by trial and error. Then the architecture and the performance of the univariate model are tested and refined in multiple iterations. We will use a fully connected network structure with four layers.

    I have chosen this architecture because it is comparably simple and a good start tackling time series problems. The architecture of our recurrent Neural Network 5.

    Our input comprises values for 50 dates. Thus the input shape needs to have at least 50 neurons — one for each value. In the last layer, we will have only one neuron, which means that our prediction will contain a single price point for a single time step. The training time may vary between seconds and minutes, depending on the computing power of your system. For instance, on my local notebook processor Intel Core i7 , the training time is usually a couple of minutes.

    Training the model model. Step 7 Making Test Predictions So how does our stock market prediction model perform? To evaluate the model performance, we need to feed the model with the test data. We need to keep in mind that initially, we have scaled the input data to a range between 0 and 1.

    Therefore, we need to inverse the MinMaxScaling from the predictions before interpreting the results. In case it is positive, our predictions tend to lie below the valid values.

    For our model, the calculated MAE is From the MAE, we can tell that our model generally tends to predict a bit too pessimistic.

    The mean squared error RMSE is always positive. More significant errors tend to have a substantial impact on the RMSE, as they are squared. In our case, the RMSE is In other words, the predictions are mostly not entirely wrong.

    Visualizing test predictions helps in the process of evaluating the model. Therefore we will plot predicted and valid values. The grey area marks the difference between test predictions and ground truth.

    As already indicated by the different performance measures, we can see that the predictions are typically near the ground truth. Prediction vs. Ground Truth We have also added the absolute errors on the bottom. Where the difference is negative, the predicted value was too optimistic. Where the difference is positive, the predictive value was too pessimistic. For this, we use a new data set as the input for our prediction model. The model returns a forecast for a single time-step, which in our case is the next day.

    Summary In this tutorial, you have learned to create, train and test a four-layered recurrent neural network for stock market prediction using Python and Keras. You can easily create models for other assets by replacing the stock symbol with another stock code. A list of common symbols for stocks or stock indexes is available on yahoo. The model created in this post makes predictions for a single time step. If you want to learn how to make time-series predictions that range further, you might want to check out the part II of this tutorial series: Creating a Multistep Forecast in Python.

    I hope you enjoyed this article. Let me know in the comments if you have questions! Since the completion of my Ph. I started this blog in with the goal in mind to share my experiences and create a place where you can find key concepts of machine learning and materials that will allow you to kick-start your own Python projects.

    A list of common symbols for stocks or stock indexes is available on yahoo. When defining the Dropout layers, we specify 0. Thereafter, we add the Dense layer that specifies the output of 1 unit. This will compute the mean of the squared errors. Next, we fit the model to run on epochs with a batch size of Keep in mind that, depending on the specs of your computer, this might take a few minutes to finish running.

    In order to predict future stock prices we need to do a couple of things after loading in the test set: Merge the training set and the test set on the 0 axis. Plotting the Results Finally, we use Matplotlib to visualize the result of the predicted stock price and the real stock price.
