MLP for implicit binary collaborative filtering

multi-layer perception

In this post, we demonstrate Keras implementation of the implicit collaborative filtering. We also introduce some techniques to improve the performance of the current model, including weight initialization, dynamic learning rate, early stopping callback etc. The implicit data For demonstration purposes, we use the dataset generated from negative samples using the technique mentioned in this post...

Create and distribute your python package

python package

This is a quick guide for create and generate distribution package of your python project so that others can install, import and use in their projects. Prerequisites: You will need the following tools installed in your computer: Python (2.x/3.x)PipAPI key for uploading your package to distribution platform, such as test.pypi.org. After install python, you can install pip by using: 12 curl -o get...

Fast uniform negative sampling for rating matrix

Petamind A.I

Sometimes, we want to reduce the training time by using a subset of a very large dataset while the negative samples outnumbers the positive ones, e.g. word embedding. Another situation when we deal with implicit data. In this case, we may need to populate new data for negative values. This post demonstrates how to generate data for training using uniform negative sampling. The data Originally...

Metrics for regression and classification – quick note

In this article, we review some common metrics and their uses for two main ML problems, i.e. regression and classification. Regression Metrics Most of the blogs have focussed on classification metrics like precision, recall, AUC etc. For a change, I wanted to explore all kinds of metrics including those used in regression as well. MAE and RMSE are the two most popular metrics for continuous...

Prevent colab from disconnecting with console js

Petamind A.I

This quick note is one solution (may not optimal) to prevent Colab from disconnecting during training your deep learning model. disconnect Problem Recently, my Google Colab notebook often gets disconnected after a while, and the data is lost. I searched and found a solution. So reshare this here. SOLUTION So to prevent this, we add a JS code to the console. Its purpose is to keep on clicking the...
