Building a #datascience #machinelearning #algorithm is relatively simple.

8 lines of #python code.

It’s the other process steps that require most of the work – problem definition, #datawrangling, model selection, #optimization, deployment, continuous improvement. Giving an example to build a #randomforest model for predicting US 10year #treasury #bond prices using a few #macroeceonomic data points.

Charts show good accuracy

# 1. Import Bond Price and macroeconomic data for US

# 2. Split the data into dependent y and independent X variables

X = usmacro10yrpriceyielddata.iloc[:, 1:7].values

y = usmacro10yrpriceyielddata.iloc[:, 7].values

# 3. As y is a 1 dimensional array, and the algorithm expects a 2D array

# we need to reshape the array. Using numpy reshape method this can be done easily

y = y.reshape(-1,1)

# 4. Split the data into training and test set

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.25)

# 5. Create the random forest regressor

estimator = RandomForestRegressor(n_estimators=100, criterion=’mse’, min_samples_leaf=1, min_samples_split=2,

max_features=’auto’, random_state=42, n_jobs=-1)

# 6. Fit the estimator to the training data to build the model

estimator.fit(X_train, y_train)

# 7. Using the estimator predict y values using the X test data

y_pred = estimator.predict(X_test)

# 8. Calculate error metrics for predicted y values vs y test data

mse = mean_squared_error(y_test , y_pred)

rmse = np.sqrt(mse)
