<p>This object wraps a dictionary, whos keys are _operations_ that we’d like
|
|
to apply to a parameter array, and whose values are np integer arrays which
|
|
index the parameter array appropriately.</p>
|
|
<p>A model instance will contain one instance of this class for each thing
|
|
that needs indexing (i.e. constraints, ties and priors). Parameters within
|
|
the model constain instances of the ParameterIndexOperationsView class,
|
|
which can map from a ‘local’ index (starting 0) to this global index.</p>
|
|
<p>Here’s an illustration:</p>
|
|
<p>#=======================================================================
|
|
model : 0 1 2 3 4 5 6 7 8 9
|
|
key1: 4 5
|
|
key2: 7 8</p>
|
|
<p>param1: 0 1 2 3 4 5
|
|
key1: 2 3
|
|
key2: 5</p>
|
|
<p>param2: 0 1 2 3 4
|
|
key1: 0
|
|
key2: 2 3
|
|
#=======================================================================</p>
|
|
<p>The views of this global index have a subset of the keys in this global
|
|
(model) index.</p>
|
|
<p>Adding a new key (e.g. a constraint) to a view will cause the view to pass
|
|
the new key to the global index, along with the local index and an offset.
|
|
This global index then stores the key and the appropriate global index
|
|
(which can be seen by the view).</p>

<li>self[:,1].constrain_positive()</li>
|
|
<li>self[0].tie_to(other)</li>

<li>self.untie()</li>

<li>self[:3,:].unconstrain()</li>
|

<li>self[1].fix()</li>

the fixed value, it will be fixed to the new value!</p>

<div><p>Name: The name of the param, can be renamed!
|
|
Value: Shape or value, if one-valued
|
|
Constrain: constraint of the param, curly “{c}” brackets indicate</p>
|
|
<blockquote>
|
|
<div>some parameters are constrained by c. See detailed print
|
|
to get exact constraints.</div></blockquote>
|
|
<p>Tied_to: which paramter it is tied to.</p>
|

|
|
<p>Getting and setting parameters:</p>
|
|
<blockquote>

<div><p>Set all values in param to one:</p>
|
|
<blockquote>
|
|
<div>m.name.to.param = 1</div></blockquote>
|
|
</div></blockquote>
|
|
<p>Handling of constraining, fixing and tieing parameters:</p>
|
|
<blockquote>
|
|
<div><p>You can constrain parameters by calling the constrain on the param itself, e.g:</p>
|
|
<blockquote>
|
|
<div><ul class="simple">
|
|
<li>m.name[:,1].constrain_positive()</li>
|
|
<li>m.name[0].tie_to(m.name[1])</li>
|
|
</ul>
|
|
</div></blockquote>
|
|
<p>Fixing parameters will fix them to the value they are right now. If you change
|
|
the parameters value, the param will be fixed to the new value!</p>
|
|
<p>If you want to operate on all parameters use m[‘’] to wildcard select all paramters
|
|
and concatenate them. Printing m[‘’] will result in printing of all parameters in detail.</p>

<p>The new parameter tie framework. (under development)</p>
|
|
<p>All the parameters tied together get a new parameter inside the <em>Tie</em> object.
|
|
Its value should always be equal to all the tied parameters, and its gradient
|
|
is the sum of all the tied parameters.</p>
|
|
<p>=====Implementation Details=====
|
|
The <em>Tie</em> object should only exist on the top of param tree (the highest parent).</p>
|
|
<p>self.label_buf:
|
|
It uses a label buffer that has the same length as all the parameters (self._highest_parent_.param_array).
|
|
The buffer keeps track of all the tied parameters. All the tied parameters have a label (an interger) higher
|
|
than 0, and the parameters that have the same label are tied together.</p>
|
|
<p>self.buf_index:
|
|
An auxiliary index list for the global index of the tie parameter inside the <em>Tie</em> object.</p>
