How is the axis indexed in NumPy’s array?

How is the axis indexed in NumPy’s array?

By definition, the axis number of the dimension is the index of that dimension within the array's shape. It is also the position used to access that dimension during indexing. So we'll be learning how is the axis indexed For example, if a 2D array a has shape (5,6), then you can access a[0,0] up to a[4,5]. Axis 0 is thus the first dimension (the "rows"), and axis 1 is the second dimension (the "columns"). In higher dimensions, where "row" and "column" stop really making sense, try to think of the axes in terms of the shapes and indices involved. If you do  .sum(axis=n), for example,…

Stationarity Analysis in Time Series Data

Stationarity Analysis in Time Series Data

Hey Geeks !!! in this blog, we'll dive into the concept of stationarity using time series data. We'll first understand what is time-series data, what is stationarity, why and when data should be stationary etc...We'll use the dataset I created specifically for this blog to analyze whether the data is stationary or not. We'll also see how to convert the non-stationary data to stationary.

How to create Movie Recommendation System

How to create Movie Recommendation System

In this notebook, I will try to use a few recommendation algorithms (content-based, popular-based and shared filters) and try to build a collection of these models to come up with our final movie recommendation system. For us, we have two MovieLens data sets. Full Data Set: Contains 26,000,000 ratings and 750,000 tag requests applied to 45,000 movies by 270,000 users. Includes genome tag data with 12 million affiliate scores on 1,100 tags.Small Data Set: Includes 100,000 ratings and 1,300 tag applications applied to 9,000 movies by 700 users.I will create a Simple Recommendation using movies from the Full Database while…

How to Predict Movie will be Flop or Hit and it’s Revenue?

How to Predict Movie will be Flop or Hit and it’s Revenue?

The Birth of the motion picture camera in the late 18th century gave birth to the most powerful form of entertainment available: Cinema. Movies have been able to entertain audiences from the emergence of a single second of horse racing in the 1890s to the introduction of sound in the 1920s to the birth of color in the 1930s to create 3D Movies in early 2010. Cinema had a humble background in terms of design, direction and acting (especially due to its very short time in its early days) but since then, the film industry around the world has been…

How to create a simple movie recommendation System

Introduction This part of the Content Editor Internship ” “Every time I go to a movie, it's magical, no matter what the movie is about. - Steven Spielberg Everyone loves movies regardless of age, gender, race, color, or location. We are all in some way connected to each other in this amazing way. But most interesting is the fact that our choices and combinations are different in terms of our preferences. Some people like movies that are specific to the genre, be it entertaining, romantic, or sci-fi, while others focus on the main characters and directors. Considering all of that,…

Table of Contents What is Dimensionality ReductionWhy Dimensionality Reduction is ImportantDimensionality Reduction Methods and ApproachesDimensionality Reduction TechniquesDimensionality Reduction Example Learning by machine is not an easy task. Okay, so that's a lesser statement. Artificial Intelligence and machine learning represent a major step in making computers think like humans, but both concepts are challenging to understand. Fortunately, the profit is worth the effort. Today we are dealing with the process of reducing size, analyzing a key component in machine learning. We will cover its meaning, why it is important, how to do it, and give you a related example to illustrate…

Interpreting ACF and PACF | Time Series

Introduction Autocorrelation analysis is an important step in the Exploratory Data Analysis (EDA) of time series. The autocorrelation analysis helps in detecting hidden patterns and seasonality and in checking for randomness. It is especially important when you intend to use an ARIMA model for forecasting because the autocorrelation analysis helps to identify the AR and MA parameters for the ARIMA model.
