Object Detection

U-Net and IoU for Object Detection in Image Processing

Other than our last  hand writing challenge, there is another Kaggle challenge featuring image recognition — TGS Salt Identification Challenge. But this time, we are going for an “upgrade”. As we are dealing with object detection. It is all about salt. In this challenge, our mission is finding geophysical images that contain salt. Oh wait, does it sound weird? Actually …

The Dark Side of Blending

Blending, the Dark Side in Data Science Competition

In our past machine learning topic, “Ensemble Modeling“, we mentioned how blending helps on improving our prediction. Then in another topic, “Why are people frustrated on Kaggle’s challenge?“, we mentioned how blending ruins a data science competition. Okay, we have a question here, is blending good or bad?

Vodka Boosting

TFIDF technique and Deal Probability Prediction (in Russian)

Our topic this time is too Russia, so my water just turned into Vodka :]] . Actually, this is all about Kaggle’s competition: Avito Demand Prediction Challenge. Avito is the biggest classified site in the Mother Russia, just likes the Craigslist. Our mission for this time is, predicting the rate that a seller can make a …

Teach our machine with Convolutional Neural Network

Python Image Recognizer with Convolutional Neural Network

On our data science journey, we have solved classification and regression problems. What’s next? There is one popular machine learning territory we have not set feet on yet — the image recognition. But now the wait is over, in this post we are going to teach our machine to recognize images by using Convolutional Neural …
