It contains an Artificial Neural Net implemented from scratch in Python.

KMeans is an unsupervised Machine Learning Algorithm, which is implemented from scratch here. Iris dataset is used for testing and training

K- Nearest Neighbor Classification Algorithm is widely used for classification problem. Here, the algorithm is implemented from scratch and tested first on a small example of 2 dimensional test data and then on iris dataset.

In Linear Regression, we try to establish relationship between 2 variables by fitting a line. The best fit line is known as regression line and it is represented by a linear equation Y = a*X +b This folder contains Linear Regression implemented from scratch in Python without using any Machine Learning libraries.

Logistic Regression is basically a classification algorithm which is used to estimate discrete values based on given data. The folder contains an ipython notebook depicting the implementation of logistic regression without any helper machine learning libraries.

Naive Bayes is a popular classification algorithm which assumes that one variable is independent of the other. In this example, the ipython notebook implements an email spam classifier.

This folder includes the following

1. An ipython notebook depicting basic implementation of SVM algorithm for learning basis. https://github.com/aribis369/ML-Starter-Pack/blob/master/SVM/SVM.ipynb

2. Optimized SVM using the SMO Algorithm https://github.com/aribis369/ML-Starter-Pack/blob/master/SVM/SVMl.ipynb

3. A pdf for explanation of SMO Algorithm https://github.com/aribis369/ML-Starter-Pack/blob/master/SVM/smo.pdf

The folder also contains .py files of the same and some datasets for illustrating the algorithms.

Anomaly detection is a technique used to identify unusual patterns that do not conform to expected behavior, called outliers. It is used to detect intrusions in system, fraud detection and so on. The folder contains a python file which implements an anomaly detector from scratch.

Collaborative Filtering Algorithm is used in Recommender System. In collaborative filtering, the recommender system recommends items based on how users with similar interests liked it. The python file gives a collaborative filtering algorithm for recommending items to different users based on ratings and trust of reviews.

PCA (Principal Component Analysis) algorithm is used for reducing dimensions. For example, If we want to reduce our data from 3D to 2D, we can use PCA algorithm. An ipython notebook as well as a python script is added in the folder which shows the implementation of this algorithm.

Implementation of gradient descent(an optimizing algorithm) from start.

Recurrent Neural Networks allow information to persist, solving one major drawback of traditional neural nets. LSTMs are designed specially to avoid the long-term dependency problem. Remembering information for long periods of time is fortunately their default behavior, and not something they struggle to learn. A stock preditor using LSTM is implemented here.
