      abstract     = {The construction of meta-stable four-dimensional de Sitter
                      vacua in type IIB string compactifications represents an
                      important question and an ongoing area of work. There is
                      considerable support both for stringy de Sitter vacua in the
                      interior of moduli space and for their scarceness in the
                      strict asymptotic regime towards infinite-distance
                      boundaries of the compactification moduli space. Here, we
                      present evidence for the existence of uplifting vacua in the
                      three-form flux-induced scalar potential of the complex
                      structure moduli of type IIB string theory on Calabi-Yau
                      orientifolds in the cross-over region between the interior
                      of the moduli space and its strictly asymptotic
                      infinite-distance regions. Moreover, we also exhibit the
                      existence of long-range axion valleys which, while not yet
                      supporting slow-roll inflation, do show a flattened scalar
                      potential from complex structure moduli backreaction and
                      axion monodromy. We further illustrate how such regions
                      hosting axion valleys may be obtained by using machine
                      learning techniques.},
