My first Classifier Program in Weka

As I explained about the top-down approach, to get the feel of a ML program, I took up my first ML program (specifically a classifier program) in Weka platform.

I followed this article step by step and executed the program successfully. Since this article explains in detail, I’m not going to repeat what is already exist in that article.

However, I will definitely highlight key take-away for me from this exercise.

1. Got a very high level understanding of the process/steps involved in solving a problem using ML.

2. Got to know an objective of a problem statement (classification of Iris Flowers) and how data set matters.

3. Also understood the fact that choosing a ML model which provides better Classification Accuracy is an important factor.

4. I learnt about Confusion Matrix, which provides us True Positive, True Negative, False Positive, and False Negative rates.

This was just a beginning and there are so many things I need to learn in this journey! Though I didn’t get the complete picture now, I am happy that I executed my first ML program.

Ordinal Encoder, OneHotEncoder and LabelBinarizer in Python

Usually in the data set we work on, we will have both numerical data as well as categorical data (non-numeric). There are algorithms which do not work on categorical data. These algorithms are designed that way to enhance efficiency. So in such cases how do we train the model with categorical data? This is where we need to apply a technique called Encoding. Encoding transforms categorical data into numeric. There are various Encoders available in sci-kit learn library. In this post, I'll share my learning on three Encoders. Ordinal Encoder This performs ordinal (integer) encoding of categorical data. Let's look at an example. I have an array of categorical data. This is a 2 dimensional array. multiArray = np.array([[ 'Karnataka' ,  'KA' ], [ 'Maharastra' ,  'MH' ], [ 'Gujarat' ,  'GJ' ]]) Then I use OrdinalEncoder to transform this data. ordinalEncoder = OrdinalEncoder() ordinalEncoderArray = ordinalEncoder.fit_transform(mult

Natural Language Toolkit (NLTK)

To work on Natural Language Processing (NLP), we need a library. One popular Python library is Natural Language Toolkit or NLTK. As mentioned in the NLTK website , NLTK is a leading platform for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning. Some of the terms like stemming, semantic reasoning are new to me. I'll explore them in future. For now I wanted to test this library so I took the example provided in that website. First I imported nltk library import  nltk Then, formed a sample sentence sentence =  "I'm learning Natural Language Processing. Natural Language Processing is also called as NLP" Then, tokenize the text into words tokens = nltk.word_tokenize(sentence) When I ran this code, I got this error. LookupError: ********

Failed to create Anaconda menus

Image
After my first attempt at executing a  ML program in Weka  platform, I wanted to switch to Python. I did take up an online course on Python a few months back. So Python was my go-to language/library in my ML journey. As explained in  this article , I had to install Anaconda to set up the environment in my laptop. I downloaded the  Anaconda 3 2019.10 Windows 64 bit version , and when I installed (on Windows 7), it threw an error “ Failed to create menus ” as shown below. After clicking Retry a couple of times, ignored this error and went ahead with the installation. After the installation, I  could not find Anaconda program  in  Windows Start Menu . So the above error might have caused a problem in the installation itself. I tried multiple times by uninstalling and installing again but without any success. Then I came across this post in  Stack Overflow , where it was suggested to use an older version of Anaconda. So I downloaded   Anaconda 2 2019.3 Windows 64 bit version , and the inst
