Moving forward into #100DaysOfMLCode today I dived into the deeper depth of what actually Logistic Regression is and what is the math involved behind it. Learned how cost function is calculated and then how to apply gradient descent algorithm to cost function to minimize the error in prediction.
Due to less time I will now be posting a infographic on alternate days.
Also if someone wants to help me out in documentaion of code and has already some experince in the field and knows Markdown for github please contact me on LinkedIn :) .

#100DaysOfMLCode To clear my insights on logistic regression I was searching on the internet for some resource or article and I came across this article (https://towardsdatascience.com/logistic-regression-detailed-overview-46c4da4303bc) by Saishruthi Swaminathan.
It gives a detailed description of Logistic Regression. Do check it out.
Got an intution on what SVM is and how it is used to solve Classification problem.
Learned more about how SVM works and implementing the knn algorithm.
Implemented the K-NN algorithm for classification. #100DaysOfMLCode Support Vector Machine Infographic is halfway complete will update it tomorrow.
Continuing with #100DaysOfMLCode today I went through the Naive Bayes classifier. I am also implementing the SVM in python using scikit-learn. Will update the code soon.
Today I implemented SVM on linearly related data. Used Scikit-Learn library. In scikit-learn we have SVC classifier which we use to achieve this task. Will be using kernel-trick on next implementation. Check the code here.
Learned about diffrent types of naive bayes classifer also started the lectures by Bloomberg. first one in the playlist was Black Box Machine Learning. It gave the whole over view about prediction functions, feature extraction, learning algorithms, performance evaluation, cross-validation, sample bias, nonstationarity, overfitting, and hyperparameter tuning.
Using Scikit-Learn library implemented SVM algorithm along with kernel function which maps our data points into higher dimension to find optimal hyperplane.
Completed the whole Week 1 and Week 2 on a single day. Learned Logistic regression as Neural Network.
Completed the Course 1 of the deep learning specialization. Implemented a neural net in python.
Started Lecture 1 of 18 of Caltech's Machine Learning Course - CS 156 by Professor Yaser Abu-Mostafa. It was basically an intoduction to the upcoming lectures. He also explained Perceptron Algorithm.
Completed the Week 1 of Improving Deep Neural Networks: Hyperparameter tuning, Regularization and Optimization.
Watched some tutorials on how to do web scaping using Beautiful Soup in order to collect data for building a model.
Lecture 2 of 18 of Caltech's Machine Learning Course - CS 156 by Professor Yaser Abu-Mostafa. Learned about Hoeffding Inequality.
Lec 3 of Bloomberg ML course introduced some of the core concepts like input space, action space, outcome space, prediction functions, loss functions, and hypothesis spaces.

Found an amazing channel on youtube 3Blue1Brown. It has a playlist called Essence of Linear Algebra. Started off by completing 4 videos which gave a complete overview of Vectors, Linear Combinations, Spans, Basis Vectors, Linear Transformations and Matrix Multiplication.
Link to the Playlist here.
Continuing with the playlist completed Next 4 Videos discussing topics 3D Transformations, Determinants, Inverse Matrix, Column Space, Null Space and Non-Square Matrices.
Link to the Playlist here.
In the playlist of 3Blue1Brown completed another 3 Videos from the essence of linear algebra. Topics covered were Dot Product and Cross Product.
Link to the Playlist here.
Completed the whole Playlist today, Videos from 12 - 14. Really an amazing playlist to refresh the concepts of Linear Algebra. Topics covered were the change of basis, Eigenvectors and Eigenvalues, and Abstract Vector Spaces.
Link to the Playlist here.
Completing the playlist - Essence of Linear Algebra by 3blue1brown a suggestion popped up by youtube regarding a series of videos again by the same channel 3Blue1Brown. Being already Impressed by the previous series on Linear algebra I dived straight into it. Completed about 5 videos on topics such as Derivatives, Chain Rule, Product Rule, and derivative of exponential.
Link to the Playlist here.
Watched 2 Videos on topic Implicit Diffrentiation and Limits from the playlist Essence of Calculus.
Link to the Playlist here.
Watched the remaining 4 videos covering topics Like Integration and Higher order derivatives.
Link to the Playlist here.

An Amazing Video on neural networks by 3Blue1Brown youtube Channel. This video give a good understanding of Neural Networks and uses Handwritten digit dataset for expaling the concept. Link To the video.
Part two of neural networks by 3Blue1Brown youtube Channel, this video explains the concepts of Gradient Descent in an interesting way. 169 Must watch and Highly Recommended. Link To the video.
Part three of neural networks by 3Blue1Brown youtube Channel, In this video the talk is mostly about the partial derivatives and backpropagation. Link To the video.
Moved to Unsupervised Learning and studied about Clustering. Working on my website check it out avikjain.me Also Found A wonderful animation that can help to easily understand K - Means Clustering Link
