Serializing ctreectrl to/from a text file

Http://www.codeguru.com/Cpp/controls/treeview/misc-advanced/article.php/c713/ To serialize the Tree View control override the serialize () function.

Time Series mining-prediction algorithm-three exponential smoothing (holt-winters)-Three exponential smoothing algorithm can save the trend and seasonal information of time series data well

current time of the data value, the less smooth the data, α closer to 0, the smoothed value closer to the previous I data smoothing value, the more smooth data, The value of alpha can often be tried several times to achieve optimal results.The formula for predicting an exponential smoothing algorithm is: Xi+h=si, where I is the coordinates of the current last data record, that is, the predicted time series is a straight line, which does not reflect the trend and seasonality of the time series.T

Time series mining-prediction algorithm-cubic exponential smoothing (Holt-Winters)

accumulate the three exponential smoothing. below is the three exponential smoothing method. SI = α (Xi-pi-k) + (1-α) (Si-1 + ti-1) Ti = half (si-si-1) + (1-gauge) ti-1 Pi = gamma (Xi-Si) + (1-gamma) Pi-k where k is the cycle The formula for smoothing the accumulated cubic index is: XI + H = Si + HTI + pi-K + (H mod k). Note: The data charm p88 is incorrect here, which is corrected according to Wikipedia. The following formula is the three exponentia

Ch7026 debugging pen

I. IC functions Ch7026 is a TV signal generator IC that can output sdtv, HDTV, and vga TV signals. Ii. debugging instructions 1. Because the ch7026 register control is implemented through I2C, We need to debug I2C before debugging. Here I will not elaborate on it, mainly emphasizing the I2C address: the address of the ch7026 device is related to the 5th-pin as. If the grounding address is 76, this is the address with no clearance.ProgramWe need to use 0xec. 2. There are two types of ch70
