Choosing the right model for predicting a time series is always a tedious task. In this article, we will browse the points to consider to make the right choice.
Neural Network & Time-series price prediction using hourly data. We’ll build a Deep Neural Network here that does some forecasting for us and use it to predict future price. Let us load the hourly frequency data.
In this post I show you how to predict stock prices using a forecasting model publicly available from Facebook Data Science team: The Prophet
Time plays a very important role when it comes to business. Each second is money every national and global economies depends on time. Time series analysis have become a widely used tool in the field of analytics in order to understand a variable which depends on time.
The code used here is available in its original repository in .ipynb format. You can download it & fiddle with it in Jupyter Notebooks on…After spending a year or so on the self-taught path to programming with Python, I hit the reset button and started over by taking a course in _Intensive Program Design_. After just a few weeks, I picked up a load of important lessons in the fundamentals of writing software that I never cared to learn before. In a way, I finally learned enough to learn _how to learn to program_, which is a skill that I did not know I needed. In this story, I memorialize part of what I’ve learned so far, partly so I don’t forget, but also, to share a few tips on how to understand abstraction and why it is important. ## Lesson 1 — You already know abstractions, no sweat Ever use a built-in function like **sum()** to add a list of numbers or **len()** to get the length of an object in Python? If so, you already know what an abstraction is, that is, a function that hides how it does what it does so you can get on with your life. For instance, with a simple example below, we can see how **sum()** hides _how_ it adds a list of numbers by manually creating a loop that does the same job. ``` ## how to add a list of numbers, two ways lst_of_numbers = [2,3,5] ## example of using a built-in function as an abstraction sum_with_abstraction = sum(lst_of_numbers) print('With Built-in Function:', sum_with_abstraction) ## example of getting sum without a built-in function sum_with_loop = 0 for i in lst_of_numbers: sum_with_loop += i print('Without Built-in Function:', sum_with_loop) ## Output ## >>> With Built-in Function: 10 ## >>> Without Built-in Function: 10 ``` ## Lesson 1 Conclusion: So what’s the big deal about recognizing built-in functions as a form of abstraction? Most importantly— **do not be intimidated when someone throws the word _abstraction_ around because you already know what it is.** Further, it’s worth recognizing a built-in function exists for most of your programming needs and probably performs better than building something from scratch. However, what to do about other tasks without a ready-to-go function?
