  • The CodeX-Aroon Auto-Trading Approach – the AAPL Use Case

    The CodeX-Aroon Auto-Trading Approach – the AAPL Use Case

    We implement the CodeX-Aroon auto-trading strategy to examine the AAPL stock 2022 in terms of stock trends, trading signals, positions, backtesting, and benchmarking against SPY ETF. The Aroon indicator is composed of two lines. An up line which measures the number of periods since a High, and a down line which measures the number of periods since a Low. The indicator is typically applied to 25 periods of data, so the indicator is showing how many periods it has been since a 25-period high or low. When the Aroon Up is above the Aroon Down, it indicates bullish price behavior (cf. 2022-04, -08, -11) When the Aroon Down is above the Aroon Up, it signals bearish price behavior (cf. 2022-02, -03, -05, -06, -09, -10). Crossovers of the two lines can signal trend changes. For example, when Aroon Up crosses above Aroon Down it may mean a new uptrend is starting. The road ahead: this indicator should be incorporated into the comprehensive investment/trading risk management and portfolio optimization workflows.

    DJI Market State Analysis using the Cruz Fitting Algorithm

    Based upon the Cruz stochastic fitting algorithm and the colab code implementing a Hidden Markov Model, let’s predict the DJI stock returns from 1970 to 2022 and detect three states such as bull (green), sideways (yellow) and bear (red) markets. Let’s set the working directory YOURPATH import osos.chdir(‘YOURPATH’) os. getcwd() and import/install the following libraries […]

  • ML/AI Breast Cancer Diagnosis with 98% Confidence

    ML/AI Breast Cancer Diagnosis with 98% Confidence

    We demonstrate the importance of hyperparameter optimization (HPO) for enhancing ML prediction accuracy. Specifically, we will focus on the Random Forest Classifier (RFC) as an ensemble of decision trees. RFC is a supervised ML algorithm that has been applied successfully to the BC binary classification.

  • Breast Cancer ML Classification – Logistic Regression vs Gradient Boosting with Hyperparameter Optimization (HPO)

    Breast Cancer ML Classification – Logistic Regression vs Gradient Boosting with Hyperparameter Optimization (HPO)

    Breast Cancer (BC) is the leading cause of death among women worldwide. The present study optimizes the use of supervised Machine Learning (ML) algorithms for detecting, analyzing, and classifying BC. We compare Logistic Regression (LR) against Gradient Boosting (GB) Classifier within the Hyperparameter Optimization (HPO) loop given by GridSearchCV. We use the publicly available BC dataset from the University of Wisconsin Hospitals, Madison, Wisconsin, USA. Feature engineering yields 9 dominant features Results: AUC(LR)=0.987 > AUC(GBM)=0.975 It is clear that LR has the highest f1-score and POS.

  • BTC-USD Price Prediction with LSTM Keras

    BTC-USD Price Prediction with LSTM Keras

    The objective of this project is to test the deep learning algorithm of real-time BTC-USD price prediction. We trained the 2-layers Long Short Term Memory Neural Network using Bitcoin Historical Data. The trained LSTM model can be used to predict future price movements of bitcoin.  RMSE ~ $64, with the mean price of $20k (Oct ’22), which means the prediction error ~0.3%. The model performance is excellent, with an error of only tens of USD.

  • A Comparative Analysis of Breast Cancer ML/AI Binary Classifications

    A Comparative Analysis of Breast Cancer ML/AI Binary Classifications

    This study is dedicated to #BreastCancerAwarenessMonth2022 #breastcancer #BreastCancerDay @Breastcancerorg @BCAction @BCRFcure @NBCF @LivingBeyondBC @breastcancer @TheBreastCancer @thepinkribbon @BreastCancerNow. One of the most common cancer types is breast cancer (BC), and early diagnosis is the most important thing in its treatment. Recent studies have shown that BC can be accurately predicted and diagnosed using machine learning (ML) technology. Our objective is to compare different supervised ML, deep learning (DL) and data mining techniques for the early detection of BC. The idea is to analyze BC data based on its characteristics and identify the effectiveness of clustering and classification instructions for analyzing and fitting various ML models. We tested the performance of ML models by looking at their accuracies, sensitivities, specificities, and other metrics. Results obtained with the best ML model with most dominant features included showed the highest classification accuracy (~99%), and the proposed approach revealed the enhancement in accuracy performances. These results indicated the potential to open new opportunities in the BC research.
