Introduction In this post, we will learn how we can create a simple neural network to extract information ( NER) from unstructured text data with Keras. Named Entity Recognition (NER) NER is also known as entity identification or entity extraction. It is a process of identifying predefined entities present in a text such as person …
Named Entity Recognition (NER) NER is also known as entity identification or entity extraction. It is a process of identifying predefined entities present in a text such as person name, organisation, location, etc. It is a statistical model which is trained on a labelled data set and then used for extracting information from a given …
In our previous post, we discussed about getting started with knowledge graph where we saw how to install neo4j in Docker and Modelling tabular data as graph where we saw how we can push the data to our graphical database. Now that we have all the data in our graph database, we can analyse it directly in Neo4j. However a lot …
In our previous post, we discussed about getting started with knowledge graph where we only saw how to install neo4j in Docker. In this post, we will discuss about modelling the data in a graphical way. Here we have used Stack Overflow 2018 Developer Survey from kaggle to explain how we can push the data to our graphical database. …
A multi-label classification has multiple target values associated with dataset. Here we are predicting probability of each class instead of predicting a single class. In this post, I will explain about the multi-label text classification problem with fastai. Here we have used Toxic Comment Classification Challenge to explain how FastAi works for multi-label problem. Lets look …
Sentiment Analysis is the process to identify and extract subjective information from text files for determining the emotional tone behind a series of words, used to gain an understanding of the opinions and emotions expressed in text. In this post, I will explain how we extract text data to predict sentimental analysis. Here we have used …
Hey readers, in previous post I have explained How to create a python ETL Project. In this post, I will explain how we can schedule/productionize our big data ETL through Apache Airflow. Apache Airflow Airflow is an open source scheduler that helps to schedule job, executing and monitoring the workflow of job. The primary use of …
Hey Readers, I am a Data Science Student and recently I have started learning more about Data Engineering. Data Science and Data Engineering teams co-exist in all data organisations. The Data Scientists are responsible for getting insights from data and applying machine learning on data, while the Data Engineers help the Data Scientist get access …

Install MySQL Install MySQL via command prompt. For Mac: $ brew install mysql For Ubuntu : $ sudo apt-get install mysql-server After installing MySQL, we can …
Exploratory Data Analysis (EDA) is an approach to analysing data sets to summarize their main characteristics, often with visual methods. Following are the different steps involved in EDA : 1. Data Collection 2.Data Cleaning 3.Data Preprocessing 4. Data Visualisation Data Collection Data collection is the process of gathering information in an established systematic way that enables …
This post briefly describe about how to use Kaggle data on your local Jupyter Notebook. Env details: Ubuntu Python 3.6.3 Steps We need these steps for our task – Download file from Kaggle to your local box. Unzip the Zip file. Read the file from your Jupyter Notebook. Download dataset from Kaggle I am …
This small post provides information on cleaning data by dealing with missing data present in a dataframe. Data cleaning is the process of ensuring that your data is correct and useable by identifying any errors in the data, or missing data by correcting or deleting them. Cleaning up data is the first and most important …
