The kernel is the matrix of dot products of ColuMNS of the distance matrix, ie, the relationship between two points in a given space. Since the distance matrix is symmetric, so is the kernel matrix. Since the ham sandwich is two pieces of bread with stuff in the middle, so is the peanut butter n jelly sandwich. So you break apart the sandwich. And the layers reveal themselves.

ABE is good for prediction especially when different data types are used. Build clusters. Assign new project to one of the aforementioned clusters Effort Estimation Using Analogy Shepperd, Schofield, Kitchenham : ”Effort Estimation Using Analogy” , Proceedings ICSE.18 (1996) 170-178 When compared with regression and step-wise estimates, analogy performed with superior accuracy, and had the advantage of being self calibrating. In being an accurate predictor, estimation by analogy should become one of the techniques considered for estimation in the early stage of development. When using several different estimation techniques, the variance in predictions can also be used as a risk indicator. 1. How best to describe projects 2. Measure similarity, and how much confidence 3. How do we use known effort values to drive estimate (means/weighted means/etc. Differing datasets Number of observations Number of variables Effect software effort estimation DEMANDS more than one te...
Learn to see with your tongue

Your eyes, ears, mouth, nose, send info to your brain. They're called your "senses". Inputs, threshold, output (Neuron) Mathematics penalizes complexity. The more complex a model, it won't be flexible enough to fit future happenings because it was so specifically made for what happened in the past. This applies to all of us. The ability for our tongue's ability to see speaks on the simplicity of the model of our brain. The flexibility. THE BEST PLEASURES ARE THOSE FOR WHICH WE DO NOT PLAN, AND THE WORST PART OF PAIN IS EXPECTING IT AND TRYING TO GET AWAY FROM IT WHEN IT HAS COME

Immediately you have to ask yourself, "Is it worth it?" But soon enough, you must ask, "How do I measure worth?" And then you ask, "Why am I measuring? What does measuring my own experience accomplish?" I signed on to a job at a place where I have never felt so much like "That kid off the street". My brain is pushed(I allow my brain to be pushed), to the point where it is so stimulated by the pain of absorbing, problem solving, and understanding new material that after only 5 hours of work, I come home and my brain is in a state of mush that can only be explained by asking you to imagine putting your hand in a brand new solidified square of RAINBOW COLORED JELL-O. I can watch television or talk to roommates in an attempt to unwind, but soon enough my brain gives me no choice but to lie in my bed with my eyes closed, too mentally fatigued to contemplate if and when unconsciousness will hit. Usually, 5.5 hours later, my brain jolts me awa...

I felt like myself this morning. Words cannot describe how invigorating this state of being is. It is joy far greater than aggregations of happiness. At the moment I so joyfully realized I was in this state, I choked on my drink because the liquid went down the wrong pipe. While choking, I laughed, because I concluded this was God's way of drilling in the fact that peace has nothing to do with what happens to you externally, but how you react to things. Now I sit and am no longer sure I am still in the state, too consumed by my desire to eat Starbucks popcorn and soy latte's. I think the state somehow removes me from judgements and expectations I unconsciously attach to my existence. To take everything in anew. Even the use of the word anew as if it were the first time I laid my eyes on it. Ussing the word anew. Spelling ussing wrong. Knowing how to spell using roight. Spelling write rong. So forth. Ahhh glee.
Software cost estimation and anxiety

Software Cost Estimation CONTROL the cost of a project hardware travel and training effort costs (SW engineers) Use historical cost info to develop a model based on some SW metric (like size) related to the cost of the project. An estimate is made of that metric and the model predicts the effort required Parkinson's law, a project will cost whatever there is available to spend on it splitting overall cost among components calculate cost of components and sum to arrive at overall cost NO SINGLE TECHNIQUE IS ADEQUATE IN ISOLATION Parameters associated with each model are highly organization dependent Project cost estimates are self fulfilling; the estimate is used to define the project budget and the product is adjusted to meet the budget DECISION MAKING AID. Help make decisions. COCOMO -communication overhead ~familiarity, complexity EFFORT = A (KDSI) ^ b "Effort is exponential function of size" (Size ~ KDSI) development sch...
