We are facing several out of memory issues when we are doing operations on big data which present in our DB Cassandra cluster. So we decided its better to use Spark to solve this problem. It became a tough & Continue Reading
Run your first Spark program using PySpark and Jupyter notebook
I think almost all whoever have a relationship with Big Data will cross Spark path in one way or another way. I know one day I need to go for a date with Spark but somehow I was postponing for Continue Reading
How to pass a Variable or Argument to a callback function in Node.js
Recently I was taking Node.js classes for company’s training batch. I was explaining about the code reusability & callback functions at that time. At that time came across an interesting problem due to the assignment I gave to them. The Continue Reading
Profiling Node.js application using v8-profiler
As I mentioned in my previous article we are working on an application where 1ms extra CPU consumption per request is also a big deal. Adding profiler wrapper and getting the trace is ok up to one level but you Continue Reading
Review your Express.js application performance by yourself
As Mentioned in my previous articles we are working on an application which processes around 25000 requests per minute. We use only 2 core CPU machine to receive these many requests and push it to Kafka. We are confident that Continue Reading
Deploy your First Deep Learning Neural Network Model using Flask, Keras, TensorFlow in Python
Recently I built a deep learning model for my company predicting whether the user buys a car or not if yes then which car with good accuracy. Gave demo to CEO & business team everyone got excited about it. We Continue Reading
Parallelizing tasks in Node.js and Java
Recently we built a Deep Learning model for predicting whether a user who came to our sites buy a car or not if yes then which model. It is giving good results with test data. So we thought let’s do Continue Reading
Build your static content server to serve files over HTTP using Node.js/Java
When I am writing code & testing it for my last article I came across below problem. URL scheme must be “http” or “https” for CORS request This error came because of the below code. model = await tf.loadModel(‘model.json’); In Continue Reading
Handwritten Digit Prediction using Convolutional Neural Networks in TensorFlow with Keras and Live Example using TensorFlow.js
Whenever we start learning a new programming language we always start with Hello World Program. Likewise, most AI/ML developers say “Just like programming has Hello World, machine learning has MNIST”. Like everyone, I wanted to start from there. In fact, Continue Reading
Build your First Deep Learning Neural Network Model using Keras, TensorFlow in Python
Our product collects user’s behaviour (Page views, Events) on our sites. We contact every customer whether he is interested to buy a car or not? We thought what if we contact the user who is going to buy instead of Continue Reading
