Best Data Visualization Tools for 2020 Reviewed - ReadWrite

#artificialintelligence

Big data is often a buzzword. In recent years the big data word has preoccupied business owners and made department managers drool. One crucial prerequisite to big data is to utilize professional data visualization tools. These tools provide a better way to access, explore and communicate your data. Here are the ten best data visualization tools you should know for 2020. Data visualization software provides a visual representation of a company's data in the form of interactive charts and graphs.

With dtreeviz, you can visualize how the feature space is split up at decision nodes, how the training samples get distributed in leaf nodes and how the tree makes predictions for a specific observation. These operations are critical to for understanding how classification or regression decision trees work. See article How to visualize decision trees. The scikit-learn Random Forest feature importance and R's default Random Forest feature importance strategies are biased. To get reliable results in Python, use permutation importance, provided here and in our rfpimp package (via pip). A simple Python data-structure visualization tool that started out as a List Of Lists (lol) visualizer but now handles arbitrary object graphs, including function call stacks!



Decision tree visualization in python - Titanic: Machine Learning from Disaster

#artificialintelligence

Hi friends,I was struggling for Decision tree visualization in python.Sometimes there is error due to pydot and sometimes due to graphviz....even though I have installed both in my windows machine but still no luck... please let me know if you know any easy method for this visualization in ipython notebook


Hebbian Learning of Bayes Optimal Decisions

Neural Information Processing Systems

Uncertainty is omnipresent when we perceive or interact with our environment, and the Bayesian framework provides computational methods for dealing with it. Mathematical models for Bayesian decision making typically require datastructures that are hard to implement in neural networks. This article shows that even the simplest and experimentally best supported type of synaptic plasticity, Hebbian learning, in combination with a sparse, redundant neural code, can in principle learn to infer optimal Bayesian decisions. We present a concrete Hebbian learning rule operating on log-probability ratios. Modulated by reward-signals, this Hebbian plasticity rule also provides a new perspective for understanding how Bayesian inference could support fast reinforcement learning in the brain.
