How to create a null vector in numpy?
How to create a null vector in numpy?
This recipe helps you create a null vector in numpy
Recipe Objective
Null array comes quite handy while operating with numpy library in python.
So this recipe is a short example on how to create a null vector with size n in numpy. Let's get started.
Step 1 - Import the library
import numpy as np
Let's pause and look at these imports. Numpy is generally helpful in data manipulation while working with arrays. It also helps in performing mathematical operation.
Step 2 - Defining null_array function
def null_array(n):
x=np.zeros(n)
return x
We have a created a function which will produce an n sized 0 vector.
Step 3 - Printing array
print(null_array(10))
We call the null_array function of size 10.
Step 4 - Lets look at our dataset now
Once we run the above code snippet, we will see:
[0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]

Build a Music Recommendation Algorithm using KKBox's Dataset
Music Recommendation Project using Machine Learning - Use the KKBox dataset to predict the chances of a user listening to a song again after their very first noticeable listening event.
Time Series LSTM forecasting
In this project, we will use time-series forecasting to predict the values of a sensor using multiple dependent variables. A variety of machine learning models are applied in this task of time series forecasting. We will see a comparison between the LSTM, ARIMA and Regression models. Classical forecasting methods like ARIMA are still popular and powerful but they lack the overall generalizability that memory-based models like LSTM offer. Every model has its own advantages and disadvantages and that will be discussed. The main objective of this article is to lead you through building a working LSTM model and it's different variants such as Vanilla, Stacked, Bidirectional, etc. There will be special focus on customized data preparation for LSTM.

Creating your own embeddings using Glove and Word2vec
We all at some point in time wished to create our own language as a child! But what if certain words always cooccur with another in a corpus? Thus you can make your own model which will understand which word goes with which one, which words are often coming together etc. This all can be done by building a custom embeddings model which we create in this project
Digit Recognition using CNN for MNIST Dataset in Python
In this deep learning project, you will build a convolutional neural network using MNIST dataset for handwritten digit recognition.
Convolutional RCCn's for extracting the text out of images
CRNNs combine both convolutional and recurrent architectures and is widely used in text detection and optical character recognition (OCR). In this project, we are going to use a CRNN architecture to detect text in sample images. The data we are going to use is TRSynth100k from Kaggle. Given an image containing some text, the goal here is to correctly identify the text using the CRNN architecture. We are going to train the model end-to-end from scratch.
Classification - Zero to hero - Part 1
Classification is one of the basic things in ML and most of us jump to Neural networks or boosting to predict classes. But more often than not, to make the other person understand how the classification is happening, we need to use basic models like Logistic, decision trees etc. In this project we talk about you can apply various basic techniques, the maths and intuition behind them and how they paved way to bagging and boosting of the world
