In the context of finance, a portfolio is a collection of different financial assets (securities) such as stocks, bonds, exchange traded funds (ETFs), mutual funds, and/or cash. According to Markowitz (1952), the process of selecting a portfolio may be divided into two stages:
Uncertainty about the future performance of securities is the main contributor to portfolio deterioration. Because we do not possess a crystal ball to observe…
Convolutional neural networks are a special type of neural network that is used for modeling data with strong spatial correlations such as images, multivariate time-series, earth science studies (seismic classification and regression), among many other applications. Convolutional networks have gone under significant changes since 1998 and in this series of articles I aim to reproduce the famous model architecture champions such as LeNet, AlexNet, ResNet etc. My aim is to share my findings and studies with wider audiences and deliver reproducible Python notebooks.
Part 1: Lenet-5 and MNIST classification in Tensorflow:
Part 2: AlexNet classification on ImageNet and Tensorflow:

A time series is a series of data points indexed in time order. Time series resolution is the frequency that data is recorded. For example, heart rate measurements (in units of beats per minute) occur at 0.5 second intervals, so that the length of each series is exactly 15 minutes. Stock data resolution can have different resolution depending on frequency of which data is recorded like: second, minute, hour etc.

There are a plethora of stock alert systems available for free or for a nominal price. However, I found most of these alert system too simplistic (e.g. daily price movement, magnitude, etc.). Maybe I was not lucky enough to find better alert system so I decided to write an alert system on my own using Python and Windows Task Scheduler. The idea is to create a sophisticated alert system that triggers every day at market close (or open depending on your applications), finds stocks that fit your criteria, and send an email including stock symbols.
In the first part of this article (Link) we overview terminologies of upstream data, and data required to build this case study. In this part, we are going into details of how to build the dashboard. Just to refresh your memory, we are going to build following dashboard:
This panel contains number of wells in top counties. Since wells are scatter over entire region, here I limited my bar plot to counties with at least 700 wells. To accomplish this i am going to use d3.nest()
command as demonstrated below. d3.nest
is applied to EfData
by pairing county location key…
In this tutorial I am going to show you how to build a dashboard with JavaScripts and D3.js to visualize upstream oil and gas data. But before that I am going to explain some terminologies, required data, and step by step implementation. This tutorial is going to serve you as a guide on how to build consumable visualizations for clients.
The data and codes can be found on my Github Page.
You can create your own visualizations and share it with audiences here. …
Script to create this study is stored at my Github Page.
Fama (1970) introduced efficient market hypothesis (EMH), stating the prices of securities fully reflect available information. Therefore, investors buying securities in an efficient market should expect to obtain an equilibrium rate of return. Later he introduced three different form of market efficiency: weak, semi-strong, and strong. Anomalies are empirical results that seem to be inconsistent with maintained theories of asset-pricing behavior. One class of market anomalies is seasonality and changes in market trend during different seasons. Seasonality in stock returns is a closely related to week-form of market efficiency…
