Deep Learning with H2O in Python

Step 1-  First of all , we need to install H2o package in Python.

on anaconda prompt
pip install h2o

Step 2-  Initialize and start the cluster -

h2o.init()
from h2o.estimators.deeplearning import H2ODeepLearningEstimator


Step 3-  load train and test data set-

train = h2o.import_file("https://h2o-public-test-data.s3.amazonaws.com/smalldata/iris/iris_wheader.csv")

Step 4-  Creating test and train data set using split-

splits = train.split_frame(ratios=[0.75], seed=1234)



Step 5-  Configuring the model-

model = H2ODeepLearningEstimator(distribution = "AUTO",activation = "RectifierWithDropout",hidden = [32,32],input_dropout_ratio = 0.2,l1 = 1e-5,epochs = 10)

 Step 6-  train(fit the model)-

model.train(x="sepal_len", y=["petal_len"], training_frame=splits[0])

 Step 7-  predicting using trained model and creating a new column in test data-

 (splits[1]['predicted_sepal_len'])=model.predict(splits[1])

Explainability in Data Science:- Data, Model & Prediction

Image
XAI( Explainable AI  ) is grabbing lime-light in machine learning. How can we be sure that image classification algo is learning faces not background ? Customer wants to know why loan is disapproved? Globally important variable might not be responsible/ imp for individual prediction. Here XAI comes to rescue- We have taken data from  classification_data This has some sensor values and an output class.  A) Data Explainability - what are the basic understanding required from data perspective.  1)       Identify missing values, co-linear feature, feature interaction, zero importance feature, low important feature, single value feature and handle missing values, remove/ handle features accordingly. 2)       Missing values- no missing values from data description 3)       No good correlation between variables- can be seen from correlation plots 4)    ...
