Gradient Boosted Decision Trees (GBDT) are a powerful machine learning technique used primarily for regression and classification tasks. They combine the predictions of multiple weak learners, usually decision trees, to create a strong predictive model. The core idea is to build models sequentially, each new model attempting to correct the errors made by the previous ones. Have gained much popularity in the machine learning community as the algorithms of choice for ...
In the previous article, we considered the evolution of social groups where they moved freely in the search space. However, here I propose that we change this concept and assume that groups move between sectors, jumping from one to another. All groups have their own centers, which are updated at each iteration of the algorithm. In addition, we introduce the concept of memory both for the group as a whole and for each individual particle in it. Using these changes, our algorithm now allows ...
Looking at the S&P 500 E-mini Futures chart, the Fibonacci extension has reached its 100% fully measured move. So, where are we going from here? Another leg up, or will a deeper correction take place? more...
We see the recent lows in Gold as similar to the April/May 2009 consolidation after the Global Financial Crisis. Also similar to the January 2013 consolidation before an extended -34% price decline took place – ending in December 2015. The primary difference between now and then is that the US Federal Reserve is currently initiating a new round of Quantitative Tightening (QT), raising rates, while battling Inflation. In both the previous ...
The Australian Dollar fell, extending losses this past week. Will a jobs report revive some strength for AUD/USD? Technical and sentiment analysis seems to hint otherwise. Daily price is located far below Ichimoku cloud in the bearish area of the chart. The price is on secondary ranging within 0.6828/0.6967 support/resistance levels waiting for the direction of the strong bearish trend to be resumed or the secondary bear market rally to ...
